Association of serum levels of inflammatory cytokines with retinopathy of prematurity in preterm infants. Front Pediatr 2024; 11:1195904. [PMID: 38259597 PMCID: PMC10800500 DOI: 10.3389/fped.2023.1195904] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/29/2023] [Accepted: 12/19/2023] [Indexed: 01/24/2024] Open
Abstract
Introduction Retinopathy of prematurity (ROP) is a retinal vascular developmental disease associated with risks factors such as supplementary oxygen use or low birth weight/early gestational age. Multiple studies have reported associations between ROP and systemic inflammation. In this study, we investigated serum cytokines associated with ROP development and severity and assessed their applicability as potential biomarkers of ROP. Methods This prospective study was conducted at an institutional referral center between 2019 and 2021. To measure the serum levels of 40 inflammatory cytokines in eligible premature patients, we collected their serum samples during the enrollment of patients or the intravitreal injection of anti-vascular endothelial growth factor (VEGF) agents and after 2 and 4 weeks. Results Fifty patients were enrolled. In patients with type 1 ROP who received anti-VEGF agents (n = 22), the levels of serum intercellular adhesion molecule-1 decreased significantly (p < 0.05) at 4 weeks compared with the baseline level, whereas those of serum granulocyte-macrophage colony-stimulating factor increased significantly (p < 0.05). In patients with ROP who did not require any treatment (n = 14), no significant change was noted in the level of any of the 40 inflammatory cytokines. In control infants without ROP (n = 14), the serum levels of tumor necrosis factor-α, interleukin (IL)-15, and IL-12p40 increased significantly (p < 0.05) at 4 weeks. The changes in the levels of serum inflammatory cytokines did not vary significantly among the aforementioned three groups. A generalized estimating equation indicated that zone 1 ROP, stage 3 ROP, older postmenstrual age, respiratory distress syndrome, necrotizing enterocolitis, and sepsis were associated with the changes in serum cytokine levels. Conclusions Although significant changes (compared with baseline) were observed in the serum levels of certain inflammatory cytokines in patients with type 1 ROP and infants without ROP, no significant difference in cytokine level fluctuations were noted among the three groups. Changes in serum inflammatory cytokine levels may not predict ROP development or severity. Additional comprehensive studies are warranted to establish their definitive role and significance in ROP, emphasizing the need for continued research in this area.

Abstract
AIMS Narrowing or occlusion of arteries that supply the limbs can evolve to critical limb ischemia. M-CSF promotes proliferation, differentiation and survival of monocytes and macrophages, and polarization of macrophages to M2-subtype, which are essential elements for vessel formation and tissue repair. Based on these properties of M-CSF, we hypothesize that transfection of M-CSF into ischemic limbs may promote vessel formation and repair of ischemic limbs. MAIN METHODS Hindlimb ischemia was surgically induced in 10-12 weeks old Balb/c and gene therapy was performed with intramuscular application of either uP-MCSF or uP plasmids (100 μg). Macrophage and monocyte subpopulations were assessed by flow cytometry and blood flow was monitored by Laser Doppler Perfusion Imaging (LDPI). Thirty days after transfection, we assessed gastrocnemius mass and muscle force, subsequently collecting the muscle for histology. KEY FINDINGS We successfully developed the uP-MCSF plasmid, which increases M-CSF expression in the muscle transiently. Thirty days after uP-MCSF gene therapy in ischemic muscles, the treated group presented: improved muscle force, reduced fibrosis and increased arteriogenesis, although LDPI analysis did not show any significant difference in blood flow among groups. Noteworthy, we observed a temporary increase in MHCIIhighCD206high macrophages after uP-MCSF transfection. SIGNIFICANCE M-CSF gene therapy improved ischemic muscle functionality by promoting arteriogenesis and decreasing fibrosis, likely through increased MHCIIhighCD206high macrophages and not via classically known M2-macrophages.

Abstract
Segmental recanalization of chronically occluded arteries was observed in patients with chronic limb-threatening ischemia (CLTI) treated with Filgrastim, a granulocyte colony stimulating factor, every 72 h for up to a month, and an infra-geniculate programmed compression pump (PCP) for 3 h daily. Molecular evidence for fibrinolysis and neovascularization was sought. CLTI patients were treated with PCP alone (N = 19), or with Filgrastim and PCP (N = 8 and N = 6, at two institutions). Enzyme-Linked Immunosorbent Assay was used to measure the plasma concentration of plasmin and of fibrin degradation products (FDP), and the serum concentration of proteins associated with neovascularization. In the PCP-alone group, blood was sampled on Day 1 (baseline) and after 30 days of daily PCP. In the Filgrastim and PCP group, blood was drawn on Day 1, and 1 day after the 5th and the 10th Filgrastim doses. Each blood draw occurred before and after 2 h of supervised PCP. Significant (p < 0.01) PCP independent increases in the plasma concentration of plasmin (>10-fold) and FDP (>5-fold) were observed 1 day after both the 5th and the 10th Filgrastim doses, compared to Day 1. Significant (p < 0.05) increases in the concentration of pro-angiogenic proteins (e.g., HGF, MMP-9, VEGF A) were also observed. Filgrastim at this novel dosimetry induced fibrinolysis without causing acute hemorrhage, in addition to inducing a pro-angiogenic milieu conducive to NV. Further clinical testing is warranted at this novel dosimetry in CLTI, as well as in other chronically ischemic tissue beds. Trial registration. https://clinicaltrials.gov/ct2/show/NCT02802852.

Systemic Administration of G-CSF Accelerates Bone Regeneration and Modulates Mobilization of Progenitor Cells in a Rat Model of Distraction Osteogenesis. Int J Mol Sci 2021; 22:ijms22073505.

Abstract
Granulocyte colony-stimulating factor (G-CSF) was shown to promote bone regeneration and mobilization of vascular and osteogenic progenitor cells. In this study, we investigated the effects of a systemic low dose of G-CSF on both bone consolidation and mobilization of hematopoietic stem/progenitor cells (HSPCs), endothelial progenitor cells (EPCs) and mesenchymal stromal cells (MSCs) in a rat model of distraction osteogenesis (DO). Neovascularization and mineralization were longitudinally monitored using positron emission tomography and planar scintigraphy. Histological analysis was performed and the number of circulating HSPCs, EPCs and MSCs was studied by flow cytometry. Contrary to control group, in the early phase of consolidation, a bony bridge with lower osteoclast activity and a trend of an increase in osteoblast activity were observed in the distracted callus in the G-CSF group, whereas, at the late phase of consolidation, a significantly lower neovascularization was observed. While no difference was observed in the number of circulating EPCs between control and G-CSF groups, the number of MSCs was significantly lower at the end of the latency phase and that of HSPCs was significantly higher 4 days after the bone lengthening. Our results indicate that G-CSF accelerates bone regeneration and modulates mobilization of progenitor cells during DO.

Abstract
Diabetes mellitus (DM) remains one of the most important risk factors for peripheral artery disease (PAD), with approximately 20% of DM patients older than 40 years old are affected with PAD. The current standard management for severe PAD is endovascular intervention with or without surgical bypass. Unfortunately, up to 40% of patients are unable to undergo these revascularization therapies due to excessive surgical risk or adverse vascular side effects. Stem cell therapy has emerged as a novel therapeutic strategy for these ‘no-option’ patients. Several types of stem cells are utilized for PAD therapy, including bone marrow mononuclear cells (BMMNC) and peripheral blood mononuclear cells (PBMNC). Many studies have reported the safety of BMMNC and PBMNC, as well as its efficacy in reducing ischemic pain, ulcer size, pain-free walking distance, ankle-brachial index (ABI), and transcutaneous oxygen pressure (TcPO2). However, the capacity to establish the efficacy of reducing major amputation rates, amputation free survival, and all-cause mortality is limited, as shown by several randomized placebo-controlled trials. The present literature review will focus on comparing safety and efficacy between BMMNC and PBMNC as cell-based management in diabetic patients with PAD who are not suitable for revascularization therapy.

Abstract
BACKGROUND Circulating mesenchymal stem cells contribute to bone repair. Their incorporation in fracture callus is correlated to their bioavailability. In addition, Granulocyte-colony stimulating factor induces the release of vascular and mesenchymal progenitors. We hypothesized that this glycoprotein stimulates fracture healing, and analyzed the effects of its administration at low doses on bone healing. METHODS 27 adult male Sprague-Dawley rats underwent mid-femur osteotomy stabilized by centromedullar pinning. In a post (pre) operative group, rats were subcutaneously injected with 5 μg/kg per day of Granulocyte-colony stimulating factor for 5 days after (before) surgery. In a control group, rats were injected with saline solution for 5 days immediately after surgery. A radiographic consolidation score was calculated. At day 35, femurs were studied histologically and underwent biomechanical tests. FINDINGS 5 weeks after surgery, mean radiographic scores were significantly higher in the Preop group 7.75 (SD 0.42) and in the Postop group 7.67 (SD 0.52) than in the control group 6.75 (SD 0.69). Biomechanical tests showed femur stiffness to be more than three times higher in both the Preop 109.24 N/mm (SD 51.86) and Postop groups 100.05 N/mm (SD 60.24) than in control 32.01 N/mm (SD 15.78). Mean maximal failure force was twice as high in the Preop group 68.66 N (SD 27.78) as in the control group 34.21 N (SD 11.79). Histological results indicated a later consolidation process in control than in treated groups. INTERPRETATION Granulocyte-colony stimulating factor injections strongly stimulated early femur fracture healing, indicating its potential utility in human clinical situations such as programmed osteotomy and fracture.

Abstract
Spinal cord injury (SCI) is a common medical condition with a poor prognosis for recovery and catastrophic effects on a patient's quality of life. Available treatments for SCI are limited, and the evidence suggesting their harmful side effects is more consistent than any suggestion of clinical benefit. Developing novel safe and effective therapeutic options for SCI is crucial. Granulocyte colony-stimulating factor (G-CSF) is a hematopoietic cytokine with known multifaceted effects on the central nervous system. Herein, we review the accumulating preclinical evidence for the beneficial effects of G-CSF on functional and structural outcomes after SCI. Meanwhile we present and discuss multiple mechanisms for G-CSF's neuroprotective and neuroregenerative actions through the results of these studies. In addition, we present the available clinical evidence indicating the efficacy and safety of G-CSF administration for the treatment of acute and chronic traumatic SCI, compression myelopathy, and SCI-associated neuropathic pain. Our review indicates that although the quality of clinical evidence regarding the use of G-CSF in SCI is inadequate, the encouraging available preclinical and clinical data warrant its further clinical development, and bring new hope to the longstanding challenge that is treatment of SCI.

Abstract
BACKGROUND AND OBJECTIVES It has been presumed that unknown cells and growth factors in bone marrow might promote angiogenesis, so angiogenesis effect could be enhanced by autologous whole bone marrow (WBM) stem cell transplantation. We compared capillary ratio induced by autologous WBM and bone marrow-mononuclear cells (BM-MNCs) to evaluate the anigiogenic effect of auotologous WBM. In addition, the combined effect of WBM transplantation and granulocyte colony-stimulating factor (G-CSF) injection was examined in an ischemic canine model. METHODS AND RESULTS After creating ischemic limb model, autologous WBM and isolated BM-MNCs were transplanted into the ischemic muscle. In other experiments, autologous WBM with recombinant human G-CSF (rhG-CSF) and autologous WBM without rhG-CSF were transplanted into the ischemic muscle. In this study, normal saline was injected into the contralateral sites in each ischemic model as a control group. After 8 weeks of transplantation, angiography and muscle harvest were performed, and then the anigiographic findings and capillary density, as assessed by immunohistochemical staining, were investigated and analyzed. In comparison with the control group, BM-MNCs and WBM transplantation groups showed higher ratios of the capillary density (1.5±0.01 times, p<0.001 and 1.6±0.15 times, p=0.005, respectively). Between the BM-MNCs and WBM transplantation groups, the capillary ratio was 1.2 folds higher in the WBM group than that in the BM-MNCs group, but there was no significantly different (p=0.116). The angiogensis ratios of both the WBM without G-CSF group and the WBM with G-CSF groups were higher (1.6±0.15 times, p=0.004 and 1.8 ±0.01 times, p=0.005, respectively) than that of the control groups. In comparison with the WBM without G-CSF group, the WBM with G-CSF transplantation group revealed a 1.1 folds higher angiogenesis ratio, but there was no statistically significant difference (p=0.095). CONCLUSIONS Autologous WBM transplantation is a simpler method and it is not inferior for inducing therapeutic angiogenesis as compared with isolated BM-MNCs transplantation. In addition to autologous WBM transplantation, intravenous G-CSF injection enhances the angiogenic effect of autologous WBM in an ischemic limb.

Abstract
Diabetes compromises the bone marrow (BM) microenvironment and reduces the number of circulating CD34(+) cells. Diabetic autonomic neuropathy (DAN) may impact the BM, because the sympathetic nervous system is prominently involved in BM stem cell trafficking. We hypothesize that neuropathy of the BM affects stem cell mobilization and vascular recovery after ischemia in patients with diabetes. We report that, in patients, cardiovascular DAN was associated with fewer circulating CD34(+) cells. Experimental diabetes (streptozotocin-induced and ob/ob mice) or chemical sympathectomy in mice resulted in BM autonomic neuropathy, impaired Lin(-)cKit(+)Sca1(+) (LKS) cell and endothelial progenitor cell (EPC; CD34(+)Flk1(+)) mobilization, and vascular recovery after ischemia. DAN increased the expression of the 66-kDa protein from the src homology and collagen homology domain (p66Shc) and reduced the expression of sirtuin 1 (Sirt1) in mice and humans. p66Shc knockout (KO) in diabetic mice prevented DAN in the BM, and rescued defective LKS cell and EPC mobilization. Hematopoietic Sirt1 KO mimicked the diabetic mobilization defect, whereas hematopoietic Sirt1 overexpression in diabetes rescued defective mobilization and vascular repair. Through p66Shc and Sirt1, diabetes and sympathectomy elevated the expression of various adhesion molecules, including CD62L. CD62L KO partially rescued the defective stem/progenitor cell mobilization. In conclusion, autonomic neuropathy in the BM impairs stem cell mobilization in diabetes with dysregulation of the life-span regulators p66Shc and Sirt1.

Abstract
Clinical trials have failed to demonstrate an effective preventative or therapeutic strategy for bronchopulmonary dysplasia (BPD), a multifactorial chronic lung disease in preterm infants frequently complicated by pulmonary hypertension (PH). Mesenchymal stem cells (MSCs) and their secreted components have been shown to prevent BPD and pulmonary fibrosis in rodent models. We hypothesized that treatment with conditioned media (CM) from cultured mouse bone marrow-derived MSCs could reverse hyperoxia-induced BPD and PH. Newborn mice were exposed to hyperoxia (FiO2=0.75) for two weeks, were then treated with one intravenous dose of CM from either MSCs or primary mouse lung fibroblasts (MLFs), and placed in room air for two to four weeks. Histological analysis of lungs harvested at four weeks of age was performed to determine the degree of alveolar injury, blood vessel number, and vascular remodeling. At age six weeks, pulmonary artery pressure (PA acceleration time) and right ventricular hypertrophy (RVH; RV wall thickness) were assessed by echocardiography, and pulmonary function tests were conducted. When compared to MLF-CM, a single dose of MSC-CM-treatment (1) reversed the hyperoxia-induced parenchymal fibrosis and peripheral PA devascularization (pruning), (2) partially reversed alveolar injury, (3) normalized lung function (airway resistance, dynamic lung compliance), (4) fully reversed the moderate PH and RVH, and (5) attenuated peripheral PA muscularization associated with hyperoxia-induced BPD. Reversal of key features of hyperoxia-induced BPD and its long-term adverse effects on lung function can be achieved by a single intravenous dose of MSC-CM, thereby pointing toward a new therapeutic intervention for chronic lung diseases.

Abstract
Neo-vessel formation in ischemic tissues relies on numerous growth factors and cell fractions for the formation of mature, stable, functional vasculature. However, the efforts to regenerate tissues typically rely on the administration of a single growth factor or cells alone. Conversely, polymeric matrices have been investigated extensively to deliver multiple growth factors at pre-determined rates to form stable blood vessels in ischemic tissues. We report on a novel sequential delivery system of a fibrin hydrogel containing ionic-albumin microspheres that allows for the controlled release of two growth factors. The use of this system was investigated in the context of therapeutic angiogenesis. Material properties were determined based on degree of swelling measurements and degradation characteristics. Release kinetics of model angiogenic polypeptides FGF-2 and G-CSF were determined using ELISA and the bioactivity of released protein was evaluated in human endothelial cell cultures. The release of growth factors from ionic-albumin microspheres was significantly delayed compared to the growth factor released from fibrin matrices in the absence of spheres. The scaffolds were implanted in a murine critical limb ischemia model at two concentrations, 40 ng (low) and 400 ng (high), restoring 92% of the blood flow in a normally perfused limb using a fibrin hydrogel releasing FGF-2 containing albumin-PLL microspheres releasing G-CSF (measured by LDPI at the high concentration), a 3.2-fold increase compared to untreated limbs. The extent of neo-vessel formation was delineated by immunohistochemical staining for capillary density (CD-31+) and mature vessel formation (α-SMA+). In conclusion, our study demonstrated that the release kinetics from our scaffold have distinct kinetics previously unpublished and the delivery of these factors resulted in hindlimb reperfusion, and robust capillary and mature vessel formation after 8 weeks compared to either growth factor alone or bolus administration of growth factor.

Abstract
In contrast to CD3(+)/CD31(-) cells, CD3(+)/CD31(+) cells aid in endothelial repair and revascularization. There are limited data regarding the functional differences between circulating CD3(+)/CD31(+) and CD3(+)/CD31(-) cells that may contribute to their divergent cardiovascular effects. The aim of the present study was to characterize functional differences between CD3(+)/CD31(+) and CD3(+)/CD31(-) cells. To address this aim, migratory capacity, proangiogenic cytokine release and apoptotic susceptibility of CD3(+)/CD31(+) and CD3(+)/CD31(-) cells were determined. Human CD3(+)/CD31(+) and CD3(+)/CD31(-)cells from peripheral blood were isolated using magnetic-activated cell sorting. CD3(+)/CD31(+) cells demonstrated significantly higher ( approximately 60%) migratory capacity to the chemokines SDF-1alpha (655+/-99 vs. 273+/-54 AU) and VEGF (618+/-99 vs. 259+/-57 AU) vs. CD3(+)/CD31(-) cells. Release of angiogenic cytokines G-CSF, interleukin-8 and matrix metallopeptidase-9 were all approximately 100% higher (P<0.05) in CD3(+)/CD31(+) than CD3(+)/CD31(-) cells. CD3(+)/CD31(+) cells exhibited significantly higher intracellular concentrations of active caspase-3 (2.61+/-0.60 vs. 0.34+/-0.09 ng/mL) and cytochrome-c (21.8+/-1.4 vs. 13.7+/-1.0 ng/mL). In summary, CD3(+)/CD31(+) cells have greater migratory and angiogenic cytokine release capacity, but are more susceptible to apoptosis compared with CD3(+)/CD31(-) cells. Enhanced migratory capacity and angiogenic cytokine release may contribute to the vasculogenic properties of this unique T cell subpopulation.

Abstract
BACKGROUND The dysfunction of vascular endothelial cells plays a key role in starting arterial restenosis. The circulating endothelial progenitor cells (EPCs) can be mobilised by cytokines and are recruited to sites of injury, where they may participate in intima repair and the recovery of endothelial function. In the present study, we examined the hypothesis that mobilisation of EPCs by exogenous recombinant human granulocyte-colony stimulating factor (rhG-CSF) can promote vascular proliferation, reduce vascular inflammation and decrease the rate of restenosis. METHODS Male rats were randomly divided into the rhG-CSF and control groups. The animals were injected daily with 30 microg/kg rhG-CSF or 0.9% NaCl subcutaneously for 7 days, then the animals underwent balloon angioplasty of the common carotid artery. The animals were euthanased at 2 or 4 weeks after injury, and the carotid arteries were harvested and processed for immunohistochemistry, scanning electron microscopy (SEM), morphometric analysis of endothelialisation and neointimal formation at 1 hour, and 3, 7, 14 and 28 days after injury. Immunohistochemistry for proliferation cell nuclear antigen (PCNA) and reverse transcriptase polymerase chain reaction (RT-PCR) for endothelial nitric oxide synthase (eNOS) mRNA were also conducted for evaluating the proliferation of cells of the vessel wall and the possible mechanism of the repairing. RESULTS Four weeks after balloon damage, SEM showed increased re-endothelialisation of the denuded vessels in the G-CSF treated animals compared with the control animals [(60.6 +/- 7.3)% versus (41.6 +/- 3.3)%, p < 0.01]. Re-endothelialisation was paralleled by a decrease in inflammation in the vessel wall. Histological examination showed that neointimal formation, vascular smooth muscle cells and fibrous tissue of the G-CSF group were less than those of the control group. Morphometry showed the lumen area of the G-CSF group was larger than that of the control group, and the neointimal area and percent of intimal hyperplasia were significantly smaller than those of the control group. Immunohistochemical staining for PCNA positive cells was less in the G-CSF treated animals compared with the control animals (42.9% versus 72.8%, p < 0.01). CONCLUSION rhG-CSF-induced mobilisation of EPCs regenerated endothelium and inhibited neointimal hyperplasia after vascular injury. This cytokine therapy may be a feasible strategy for the promotion of re-endothelialisation after angioplasty.

Abstract
OBJECTIVE To investigate a potential immunomodulatory effect of the 60-kd heat-shock protein (Hsp60) on experimental spontaneous Sjögren's syndrome (SS). METHODS Seven-week-old nonobese diabetic (NOD) mice were immunized with eukaryotic Hsp60 or an Hsp60-derived peptide (amino acid residue [aa] 437-460). At 21 weeks of age, nondiabetic mice were investigated for salivary gland inflammation, exocrine function, and extraglandular disease manifestations. In addition, biomarker profiles comprising 87 analytes in serum and 75 in saliva were analyzed. RESULTS In mice immunized with Hsp60 and aa 437-460, SS-related histopathologic features were significantly reduced compared with NOD controls. In addition, 50% of Hsp60-injected mice and 33% of aa 437-460-injected mice retained normal exocrine function. Both treatments induced similar changes in biomarker profiles. Notably, levels of circulating interferon-gamma-inducible 10-kd protein (IP-10) and eotaxin were decreased significantly after treatment. Anti-type 3 muscarinic acetylcholine receptor (anti-M3R) IgG1, interleukin-10, and leptin discriminated best between the different treatment groups. Successful prevention of hyposalivation was accompanied by quantitative alterations in 36 biomarkers, of which 19 mediators of inflammation declined to levels comparable with those found in BALB/c mice. Low secreted vascular endothelial growth factor A was the most accurate predictor of successful prevention of hyposalivation. Low salivary granulocyte chemotactic protein 2 was identified as the best predictor of normal secretory function across the strains. CONCLUSION Immunization with Hsp60 and its peptide aa 437-460 led to inhibition of SS in NOD mice. Comprehensive analyses revealed specific biomarker signatures capable of predicting treatment group and treatment outcome. Molecules involved in inflammatory chemotaxis, neovascularization, and regulatory pathways caused the differences displayed by the biomarker profiles.

Abstract
In this study the effects of granulocyte-colony stimulating factor (G-CSF) on angiogenesis and the survival of ischaemic skin flaps are evaluated. Thirty adult Wistar rats were equally randomised into three groups. Caudal-based, ischaemic skin flaps of 10 x 3 cm were designed on the back and injected with saline in group 1 and with 100 microg/kg G-CSF in groups 2 and 3. The injections were performed just prior to flap elevation in groups 1 and 2 and 2 days earlier in group 3. Peripheral leukocyte counts, tissue myeloperoxidase enzyme assays, necrotic to total flap area ratio (NA/TA) calculations, flap tissue inflammation gradings, immunohistochemical vessel counts, and electron microscopic evaluation of endothelial cells were performed on the 8th day. No significant difference was encountered between the groups in terms of the leukocyte counts, myeloperoxidase enzyme assays and inflammation gradings (P > 0.05), demonstrating the absence of an increased inflammatory response within the flap tissue. The surviving flap portions were observed to be increased with the application of G-CSF. The mean NA/TA results (when measured in situ) were 0.44+/-0.13 for group 1, 0.30+/-0.17 for group 2, and 0.22+/-0.16 for group 3. The difference between groups 1 and 3 was statistically significant (P = 0.009). The mean vessel count was 3.53+/-1.20 in group 1, 7.36+/-1.41 in group 2 and 7.43+/-0.92 in group 3. The differences between groups 1 and 2 and groups 1 and 3 were statistically significant (P < or = 0.001). Early apoptotic changes were encountered in the endothelial cells of group 1, while activated and proliferating endothelial cells were seen in groups 2 and 3 with electron microscopy. G-CSF promotes angiogenesis by increasing the number of activated and proliferating endothelial cells within the ischaemic flaps by the resettlement of G-CSF-stimulated endothelial progenitor cells into the ischaemic tissue. The overall result is an improved survival of ischaemic skin flaps. These effects are more pronounced when G-CSF is introduced 2 days prior to flap elevation.

Abstract
In the light of the enthusiasm to use of recombinant human granulocyte colony-stimulating factor (G-CSF) for immunomodulation and neuroprotection, it should be remembered that the current knowledge is based on a century of laborious research. G-CSF is a pleiotropic cytokine playing a major role as regulator of haematopoiesis. Although the precise mechanisms of G-CSF are not known, there is growing evidence supporting the notion that G-CSF also exerts profound immunoregulatory effect in adaptive immunity and has a neuroprotective role in both cerebral ischemia and neurodegeneration. Here, we describe the immunomodulation and the neuroprotection that can be achieved with G-CSF, and summarize possible mechanisms of G-CSF as a potential therapeutic agent in autoimmune diseases and neurological disorders. Our understanding of these novel sites of action of G-CSF has opened therapeutic avenues for the treatment of autoimmune diseases and neurological disorders, and has translated the beneficial effects of G-CSF from basic experiments to clinical patients.

Abstract
We investigated bone marrow mononuclear cells (BM-MNCs) and peripheral blood mononuclear cells (PB-MNCs) for therapeutic angiogenesis in the ischemic hindlimb. BM-MNCs were isolated and injected into ischemic skeletal muscles in mice. Laser Doppler and histological evaluation were performed after the surgical procedure. Fifteen patients suffering from critical lower limb ischemia received subcutaneous injections of recombinant human granulocyte colony-stimulating factor (G-CSF) to mobilize progenitor cells, and PB-MNCs were harvested and transplanted directly into the ischemic limb. Endothelial cells derived from BM-MNCs were plated, then induced to form three-dimensional networks by invading a Matrigel. Four weeks after implantation of BM-MNCs, laser Doppler analysis showed that the blood flow ratio was significantly increased (0.67 +/- 0.02 vs. 0.44 +/- 0.02). Alkaline phosphatase and immunohistochemical analyses showed that capillary density was significantly increased (95.25 +/- 0.07% vs. 39.6 +/- 0.04%). Two months after implantation of PB-MNCs, in both subgroups, ankle-brachial index values, walking distance, pain scale, and transcutaneous oxygen pressure (TcO(2)) were significantly improved (p < 0.005). A total of six of 15 limb ulcers of transplanted patients were healed after cell transplantation. BM-MNC implantation was able to induce functional angiogenesis in mice ischemic hindlimb. This clinical trial shows that G-CSF-based PB-MNC transplantation is a feasible treatment for the ischemic hindlimb.

Abstract
In addition to their multilineage potential, mesenchymal stem cells (MSCs) also have a wide range of functionality. Not only can MSCs reconstruct a tissue, but they also have the ability to control or cure other cells and can reconstruct a coordinating function. The opportunity to control other cells depends on MSCs being able to secrete factors like cytokines and chemokines. Therefore, we focused on asking, Which factors can be secreted by human MSCs? To answer this question, we analyzed the secreting profile of in vitro-expanded MSCs by using cytokine arrays. The media concentrations of 44 of the 120 analyzed cytokines were significantly increased by MSCs. Conversely, concentrations of 40 cytokines given with the sera were significantly decreased. The data presented here provide an overview about a large range of factors that were secreted by MSCs under cell culture conditions. These data indicate that MSCs demonstrate all previously described functions in cellular interactions without an external stimulus. The MSCs secreted angiogenic, immunosuppressive, anti-apoptotic, and proliferation-stimulating factors.

Abstract
For end-stage liver disease, liver transplantation provides the only definite cure; however, many patients die while in the waiting list for donation. Various stem cell populations have been described to contribute to liver regeneration and there is accumulating evidence for the participation of hematopoietic stem cells (HSCs) in this process. We here report two cases treated with boost infusions of autologous mobilized HSCs to regenerate cirrhotic liver. The procedure was safe and well tolerated. Both patients showed a lasting amelioration in the clinical course of the disease during the 30 months of follow-up. These results suggest that the procedure may be considered in a clinical study setting as a bridging therapy until organ transplantation becomes available or to reverse a decompensated cirrhosis to a compensated one. Additional studies in this area will be required to document efficacy and evaluate toxicity.

Abstract
INTRODUCTION Macrophage colony stimulating factor (M-CSF) is a key factor for monocyte and macrophage survival and proliferation. M-CSF has been implicated in cardiac healing and repair after myocardial infarction. METHODS AND RESULTS We show by immunohistochemistry and Western blotting analysis that M-CSF protein is present in human heart tissue. Cultured human adult cardiac myocytes (HACM) and human adult cardiac fibroblasts (HACF) isolated from human myocardial tissue constitutively express M-CSF. When HACM and HACF were treated with tumor necrosis factor-alpha (TNF-alpha) M-CSF protein production and M-CSF mRNA expression, determined by ELISA or by using RT-PCR, respectively, was significantly increased. To determine a possible role of nuclear factor kappaB (NF-kappaB) and activating protein 1 (AP-1) in M-CSF regulation, blockers to both pathways and an adenovirus overexpressing a dominant negative (dn) form of IkappaB kinase 2 (IKK2) were used. Only the NF-kappaB blocker dimethylfumarate and the dn IKK2, but not januskinase inhibitor-1 (JNK-I), were able to block the TNF-alpha-induced increase in M-CSF production in these cells, suggesting that the induction of M-CSF through TNF-alpha is mainly dependent on the activation of the NF-kappaB pathway. The monocyte activation marker CD11b was significantly increased after incubating U937 cells with conditioned medium from HACM or HACF as determined by FACS analysis. CONCLUSIONS Our in vitro data taken together with our immunohistochemistry data suggest that human cardiac cells constitutively express M-CSF. This expression of M-CSF in the human heart and its upregulation by TNF-alpha might contribute to monocyte and macrophage survival and differentiation.

Abstract
Peripheral arterial disease (PAD) is a major health problem, especially when associated with severe hypertension. Administration of autologous bone marrow cells (BMCs) is emerging as a novel intervention to induce neoangiogenesis in ischemic limb models and in patients with PAD. This study evaluates the neovascularization capacity of BMCs alone or in combination with metabolic cotreatment (0.8% vitamin E, 0.05% vitamin C, and 5% of L-arginine) in a rat model of ischemic hindlimbs of spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY). Molecular mechanisms were investigated in bone marrow-derived endothelial progenitor cells (BM-EPC) derived from rats. BMC therapy increased blood flow and capillary densities and Ki67 proliferative marker, and it decreased interstitial fibrosis. These effects were amplified by metabolic cotreatment, an intervention that induces vascular protection at least partly through the nitric oxide (NO)/endothelial nitric oxide synthase (eNOS) pathway, reduction of systemic oxidative stress, and macrophage activation. In addition, BMC therapy alone and, more consistently, in combination with metabolic treatment, ameliorated BM-EPC functional activity via decreased cellular senescence and improved homing capacity by increasing CXCR4-expression levels. These data suggest potential therapeutic effects of autologous BMCs and metabolic treatment in hypertensive PAD patients.

Abstract
To understand impaired angiogenesis in diabetic wounds, polyvinyl tubes were implanted subcutaneously in rats to form a granulation tissue for 2 weeks and the granulation tissue was studied after inducing diabetes with streptozotocin. By 1 week of diabetes, the granulation tissue was bloody and thinner than controls, its medial layer was depleted of microvessels, and the surviving vessels appeared dehisced. Vascular endothelial growth factor (VEGF) in the diabetic granulation tissue was reduced by 50% compared with control granulation tissue. After 3 days of diabetes, the diabetic tissue showed a greater degree of apoptosis in the microvessels. Chemotactic factors [stromal cell-derived factor-1alpha and chemokine receptor-4 (CXCR-4)], responsible for attracting bone marrow cells, showed equal intensity in control and diabetic tissues. As expected, progenitor endothelial CD-34 cells were observed in abundance in both the control and the diabetic granulation tissues. However, although the CD-34-positive cells appeared mostly to be integrated in the blood vessels of the control tissue, fewer such cells were present in the blood vessels of the diabetic tissues, suggesting that CD-34 failed to integrate into new blood vessels. Infusion of VEGF in the granulation tissue of diabetic rats for 1 week resulted in complete prevention of the microvascular defect compared with the contralateral granulation tissue that showed the typical diabetic changes. It was concluded that diabetes causes reduction of VEGF in the wound, resulting in loss of blood vessels by apoptosis and possible failure of CD-34 cells to integrate into the vessel structure.

Abstract
OBJECTIVE Granulocyte colony-stimulating factor (G-CSF) mobilizes bone marrow mononuclear cells into the peripheral circulation. Stromal cell-derived factor-1 (SDF-1) enhances the homing of progenitor cells mobilized from the bone marrow and augments neovascularization in ischemic tissue. We hypothesize that SDF-1 will boost the pro-angiogenic effect of G-CSF. METHODS AND RESULTS NIH 3T3 cells retrovirally transduced with SDF-1alpha gene (NIH 3T3/SDF-1) were used to deliver SDF-1 in vitro and in vivo. Endothelial progenitor cells (EPCs) co-cultured with NIH 3T3/SDF-1 cells using cell culture inserts migrated faster and were less apoptotic compared to those not exposed to SDF-1. NIH 3T3/SDF-1 (10(6) cells) were injected into the ischemic muscles immediately after resection of the left femoral artery and vein of C57BL/6J mice. G-CSF (25 mug/kg/day) was injected intraperitioneally daily for 3 days after surgery. Blood perfusion was examined using a laser Doppler perfusion imaging system. The perfusion ratio of ischemic/non-ischemic limb increased to 0.57+/-0.03 and 0.50+/-0.06 with the treatment of either SDF-1 or G-CSF only, respectively, 3 weeks after surgery, which was significantly higher than the saline-injected control group (0.41+/-0.01, P<0.05). Combined treatment with both SDF-1 and G-CSF resulted in an even better perfusion ratio of 0.69+/-0.08 (P<0.05 versus the single treatment groups). Mice were sacrificed 21 days after surgery. Immunostaining and Western blot assay of the tissue lysates showed that the injected NIH 3T3/SDF-1 survived and expressed SDF-1. CD34(+) cells were detected with immunostaining, capillary density was assessed with alkaline phosphatase staining, and the apoptosis of muscle cells was viewed using an in situ cell death detection kit. More CD34(+) cells, increased capillary density, and less apoptotic muscle cells were found in both G-CSF and SDF-1 treated group (P<0.05 versus other groups). CONCLUSION Combination of G-CSF-mediated progenitor cell mobilization and SDF-1-mediated homing of EPCs promotes neovascularization in the ischemic limb and increases the recovery of blood perfusion.

Abstract
Despite their names, the cytokines granulocyte- and granulocyte-macrophage-colony stimulating factor (G-CSF and GM-CSF respectively) have actions far beyond simply stimulating the proliferation of neutrophil and monocyte lineage cells. A comprehensive body of evidence now exists demonstrating that G-CSF and GM-CSF effectively mobilize bone-marrow-derived progenitor cells into the peripheral circulation. These mobilized progenitor cells can be conveniently harvested for use in reconstituting bone marrow by transplantation after myelo-ablative treatment of hematological malignancies. In addition, much evidence has recently emerged to suggest that these cytokines may have multiple direct and indirect beneficial cardiovascular effects--including neovascularization of ischemic myocardium and reducing the extent of myocardial damage after infarction. Based on this knowledge and a strong safety record in hematological applications, a number of early clinical trials have evaluated the use of G-CSF or GM-CSF in patients with both acute and chronic myocardial ischemia. Although the interpretation of these trials is complicated by heterogeneity in study design, small patient numbers and methodological concerns related to appropriate selection and blinding of patients, the results of ongoing larger phase II/III trials should soon be available to determine if these agents will be useful additions to the cardiovascular armamentarium.

Abstract
BACKGROUND Endothelial progenitor cells (EPCs) have been identified among hematopoietic tissue-derived progenitor cells that are mobilized into the peripheral blood (PB) as a result of tissue injury. It therefore seems likely that circulating EPCs have therapeutic potential by aiding in the neovascularization of ischemic tissue. This study provides clinical data on the availability of circulating EPCs at steady state and after recombinant human granulocyte-colony-stimulating factor (rHuG-CSF) mobilization and their collection by leukapheresis. STUDY DESIGN AND METHODS Eight healthy donors underwent rHuG-CSF treatment over 4 days, followed by leukapheresis. Blood samples taken before rHuG-CSF treatment and before apheresis as well as apheresis-collected samples were analyzed by flow cytometry and by real time reverse transcription-polymerase chain reaction for cells expressing EPC-specific surface markers and tissue markers, respectively, and for EPC colony-forming cells. RESULTS The median PB concentration of CD34+133+ vascular endothelial growth factor receptor-2 (VEGFR-2)-+ EPCs increased 8-fold from steady state to mobilized, and the concentration of CD34+133-VEGFR-2+ EPCs increased by 10-fold. This mobilization pattern was similar to that of hematopoietic CD34+, CD133+, and CD34+117+ progenitor cells. The increase in the median circulating colony-forming unit EPC concentration was 10-fold over baseline. The median absolute number of CD34+133+VEGFR-2+ cells collected by large-volume leukapheresis was 0.8 x 10(6) per kg of body weight. In addition, a small subset of immature CD133+34- cells coexpressing VEGFR-2 was identified in mobilized PB and in the apheresis collection. EPC-specific cells contained in the apheresis product were also identified as expressing mRNA for the CD31 antigen, Tie-2, and VEGFR-2. CONCLUSION Circulating EPCs represent a novel blood cell component that can be collected by apheresis in large quantities and can be used clinically, either unmanipulated or EPC-selected, for therapeutic vasculogenesis.

Abstract
In several experimental studies of cerebral ischaemia, G-CSF (granulocyte colony-stimulating factor) exerted neuroprotective effects through different mechanisms, including mobilization of haemopoietic stem cells, anti-apoptosis, neuronal differentiation, angiogenesis and anti-inflammation. Hence, G-CSF not only inhibits neuron death, but also generates ‘new’ neural tissue formation. A small pilot trial reports on the safety and feasibility of G-CSF therapy in stroke patients. According to this evidence, we can speculate that G-CSF, being used either alone or in combination with another agent, should have a dual activity beneficial both to acute neuronal protection and long-term plasticity after cerebral ischaemia, thus proposing that G-CSF is an ideal new drug for stroke and neurodegenerative diseases.

Abstract
OBJECTIVES Periarticular osteoporosis and joint destruction are major complications in rheumatoid arthritis (RA), caused by osteoclast-mediated bone resorption. However, the mechanisms of monocyte/osteoclast maturation and role of RA endothelial cells (RAECs) in the control of osteoclastogenesis remain unclear. The present study was designed to determine the most important factors that influence monocyte accumulation and osteoclast formation among the many factors produced by RAEC. METHODS We analysed the expression profiles of various genes in human endothelial cells from various organs (RA synovium, umbilical vein, skin, liver sinusoid, renal glomerulus and brain) using oligonucleotide microarrays. Specifically, up-regulated gene in RAECs was assessed by real-time quantitative polymerase chain reaction, enzyme-linked immunosorbent assay and immunostaining of RA synovia. Migration of monocytes was assessed by the chemotactic chamber EZ-TAXIScan. Tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cell (MNC) formation was observed by microscopy. RESULTS Among many epithelial-expressed factors, macrophage colony-stimulating factor (M-CSF) gene was abundantly expressed specifically in RAECs. Genes of fibroblast growth factor-2, interleukin-6 and osteoprotegerin were also overexpressed in RAECs. Migration of monocytes and osteoclast formation in co-cultures promoted by culture supernatants of RAECs were inhibited by M-CSF neutralizing antibody. CONCLUSIONS M-CSF produced by RAECs is involved in osteoclastogenesis from monocytes, migration and TRAP-positive MNC formation.

Abstract
OBJECTIVE Since the macrophage colony-stimulating factor (M-CSF) has been shown to stimulate differentiation and proliferation of monocyte/macrophage lineage and to be involved in the process of neointimal formation after vascular injury, we tested the effects of M-CSF on the recruitment of bone marrow-derived progenitor cells in neointimal formation after vascular injury in mice. METHODS AND RESULTS Wire-mediated vascular injury was produced in the femoral artery of C57BL/6 mice. Recombinant human M-CSF [500 microg/(kg x day)] or saline (control) was administered for 10 consecutive days, starting 4 days before the injury. Treatment with M-CSF accelerated neointimal formation in the early phase after injury, and this neointimal lesion mainly consisted of bone marrow-derived cells. M-CSF treatment had no effect on the mobilization of endothelial progenitor cells (EPCs: CD34+/Flk-1+) and reendothelialization after injury. The stromal cell-derived factor-1 (SDF-1) was markedly expressed in the neointima and media after injury, whereas CXCR4+ cells were observed in the neointima. Further, a novel CXCR4 antagonist, AMD3100, significantly attenuated the M-CSF-induced neointimal formation. CONCLUSIONS These findings suggest that M-CSF accelerated neointimal formation after vascular injury via the SDF-1-CXCR4 system, and the inhibition of this system has therapeutic potential for the treatment of cardiovascular diseases.

Abstract
BACKGROUND Lung regeneration is an innovative strategy that may cure pulmonary emphysema. The bone marrow (BM) harbors pulmonary stem cells. Hematopoietic cytokine-driven mobilization of BM cells may thus support lung regeneration. OBJECTIVES The aim of this study was to determine whether systemic administration of macrophage colony-stimulating factor (M-CSF) leads to the regeneration of lungs in a murine model of elastase-induced emphysema. METHODS C57BL/6J mice were administered elastase intratracheally. Four weeks later, in the absence or presence of elastase treatment, mice were intraperitoneally given either M-CSF or saline on days 1-5 each week for 3 weeks. Lung tissue was harvested 24 h after the last injection. RESULTS M-CSF administration without prior elastase did not affect the mean linear intercept, surface area, or surface area/lung volume. In contrast, M-CSF administration following elastase injury caused a greater increase in the mean linear intercept and greater decreases in surface area and surface area/lung volume than saline administration following elastase, indicating that M-CSF aggravated emphysema. This aggravation of emphysema was accompanied by accumulation of pulmonary alveolar macrophages (AMs) expressing metalloproteinase (MMP)-9 and MMP-12. M-CSF stimulated AMs to express MMPs in vitro. CONCLUSIONS These results suggest that M-CSF administration does not support lung regeneration but rather aggravates the lung destruction associated with elastase injury.

Abstract
BACKGROUND Autologous recellularization of decellularized heart valve scaffolds is a promising challenge in the field of tissue-engineered heart valves and could be boosted by bone marrow progenitor cell mobilization. The aim of this study was to examine the spontaneous in vivo recolonization potential of xenogeneic decellularized heart valves in a lamb model and the effects of granulocyte colony-stimulating factor mobilization of bone marrow cells on this process. METHODS Decellularized porcine aortic valves were implanted in 12 lambs. Six lambs received granulocyte colony-stimulating factor (10 microg x kg(-1) x d(-1) for 7 days, granulocyte colony-stimulating factor group), and 6 received no granulocyte colony-stimulating factor (control group). Additionally, nondecellularized porcine valves were implanted in 5 lambs (xenograft group). Angiographic and histologic evaluation was performed at 3, 6, 8, and 16 weeks. RESULTS Few macroscopic modifications of leaflets and the aortic wall were observed in the control group, whereas progressive shrinkage and thickening of the leaflets appeared in the granulocyte colony-stimulating factor and xenograft groups. In the 3 groups progressive ovine cell infiltration (fluorescence in situ hybridization) was observed in the leaflets and in the adventitia and the intima of the aortic wall but not in the media. Neointimal proliferation of alpha-actin-positive cells, inflammatory infiltration, adventitial neovascularization, and calcifications were more important in the xenograft and the granulocyte colony-stimulating factor groups than in the control group. Continuous re-endothelialization appeared only in the control group. CONCLUSION Decellularized xenogeneic heart valve scaffolds allowed partial autologous recellularization. Granulocyte colony-stimulating factor led to accelerated heart valve deterioration similar to that observed in nondecellularized xenogeneic cardiac bioprostheses.

Abstract
Background—
Granulocyte colony-stimulating factor (G-CSF) treatment was shown to inhibit neointimal formation of balloon-injured vessels, whereas neither the identification of progenitor cells involved in G-CSF–mediated endothelial regeneration with a bone marrow (BM) transplant experiment nor the functional properties of regenerated endothelium have been studied.
Methods and Results—
Recombinant human G-CSF (100 μg/kg per day) was injected daily for 14 days starting 3 days before balloon injury in the rat carotid artery. Neointimal formation of denuded vessels on day 14 was markedly attenuated by G-CSF (39% versus the control;
P
<0.05). Endothelial cell–specific immunostaining revealed an enhancement of re-endothelialization (1.8-fold increase versus the control;
P
<0.05) and inhibition of extravasation of Evans Blue dye (47%;
P
=0.02). The regenerated endothelium exhibited acetylcholine-mediated vasodilatation in NO-dependent manner. G-CSF increased the circulating c-Kit+/Flk-1+ cells (9.1-fold;
P
<0.02), which showed endothelial properties in vitro (acetylated low-density lipoprotein uptake and lectin binding) and incorporated into the regenerated endothelium in vivo. A BM replacement experiment with green fluorescent protein (GFP)–overexpressing cells showed that BM-derived GFP+/CD31+ endothelial cells occupied 39% of the total luminal length in the G-CSF–mediated neo-endothelium (2% in the control).
Conclusion—
The G-CSF–induced mobilization of BM-derived c-Kit+/Flk-1+ cells contributes to endothelial regeneration, and this cytokine therapy may be a feasible strategy for the promotion of re-endothelialization after angioplasty.

Abstract
Recently we reported that macrophage colony-stimulating factor (M-CSF) can mobilize endothelial progenitor cells (EPCs) from the bone marrow into the peripheral blood, resulting in an increase in the number of blood vessels and augmentation of blood flow in the ischemia-induced legs. M-CSF accelerates neovascularization of ischemic lesions resulting from the mobilization of EPCs. In the present paper, we analyze the mechanisms underling the mobilization of EPCs by M-CSF. M-CSF augments the production of vascular endothelial growth factor (VEGF) from the bone marrow cells, especially from myeloid lineage cells. In vivo administration of anti-VEGF antibody abrogates both the acceleration of the recovery of blood flow in the ischemia-induced limbs by M-CSF and the augmentation of the mobilization of EPCs induced by M-CSF. These results suggest that the M-CSF contributes to rapid recovery of blood flow in ischemic lesions by mobilization of EPCs from the bone marrow through augmentation of VEGF production in the bone marrow and that the VEGF is mainly produced by myeloid lineage cells.

Abstract
Lower-limb ischemia is a major health problem. Because of the absence of effective treatment in the advanced stages of the disease, amputation is undertaken to alleviate unbearable symptoms. Novel therapeutic approaches include the intramuscular use of autologous bone marrow cells (BMCs). Because tissue ischemia is associated with an overwhelming generation of oxygen radicals and negative effects due to perturbed shear-stress, metabolic intervention with antioxidants and l-arginine could potentially induce beneficial effects beyond those achieved by BMCs. The protective effect of autologous BMCs and vascular protection by metabolic cotreatment (1.0% vitamin E added to the chow and 0.05% vitamin C and 6% l-arginine added to the drinking water) were examined in ischemia-induced angiogenesis in the mouse hindlimb, a model of extensive acute peripheral arterial occlusion. i.v. BMC therapy improved blood flow and increased capillary densities and expression of Ki-67, a proliferation-associated protein. This beneficial effect was amplified by metabolic cotreatment, an intervention inducing vascular protection, at least in part, through the nitric oxide pathway, reduction of systemic oxidative stress, and macrophage activation. Therefore, although a cautious approach is mandatory when experimental findings are extended to human diseases, autologous BMCs together with metabolic intervention could be an effective clinical treatment for peripheral arterial disease.

Abstract
Recently, we have demonstrated that bone marrow stem cells can differentiate into retinal nerve cells. In the present study, we show a new and efficient strategy for transplanting bone marrow stem cells into the retina. When bone marrow stem cells were injected into the vitreous cavity of untreated eyes, only very few cells were found in the retina 2 weeks after injection. In contrast, when laser photocoagulation was performed just before the injection of bone marrow stem cells, a large number of the injected cells survived 2 weeks after injection and the cells expressed neural cell-specific or retinal nerve cell-specific antigens. Moreover, we still detected bone marrow stem cell-derived retinal nerve cells in the retina 1 year after injection in the retina.

Abstract
OBJECTIVE To assess the application of autologous transplantation of granulocyte colony-stimulating factor (G-CSF)-mobilized peripheral blood mononuclear cells (PBMNCs) in the treatment of critical limb ischemia (CLI) of diabetic patients and to evaluate the safety, efficacy, and feasibility of this novel therapeutic approach. RESEARCH DESIGN AND METHODS Twenty-eight diabetic patients with CLI were enrolled and randomized to either the transplant group or the control group. In the transplant group, the patients received subcutaneous injections of recombinant human G-CSF (600 microg/day) for 5 days to mobilize stem/progenitor cells, and their PBMNCs were collected and transplanted by multiple intramuscular injections into ischemic limbs. All of the patients were followed up after at least 3 months. RESULTS At the end of the 3-month follow-up, the main manifestations, including lower limb pain and ulcers, were significantly improved in the patients of the transplant group. Their laser Doppler blood perfusion of lower limbs increased from 0.44 +/- 0.11 to 0.57 +/- 0.14 perfusion units (P < 0.001). Mean ankle-brachial pressure index increased from 0.50 +/- 0.21 to 0.63 +/- 0.25 (P < 0.001). A total of 14 of 18 limb ulcers (77.8%) of transplanted patients were completely healed after cell transplantation, whereas only 38.9% of limb ulcers (7 of 18) were healed in the control patients (P = 0.016 vs. the transplant group). No adverse effects specifically due to cell transplantation were observed, and no lower limb amputation occurred in the transplanted patients. In contrast, five control patients had to receive a lower limb amputation (P = 0.007, transplant vs. control group). Angiographic scores were significantly improved in the transplant group when compared with the control group (P = 0.003). CONCLUSIONS These results provide pilot evidence indicating that the autologous transplantation of G-CSF-mobilized PBMNCs represents a simple, safe, effective, and novel therapeutic approach for diabetic CLI.
