Abstract
OBJECTIVE In prevous studies, we established a new animal model, KLF5+/- ;Fli-1+/- mice, in which fundamental pathologic features of systemic sclerosis (SSc) are broadly recapitulated. SSc vasculopathy is believed to occur as a result of impaired vascular remodeling, but its detailed mechanism of action remains unknown. To address this, the present study investigated the properties of dermal microvascular endothelial cells (DMECs), bone marrow-derived endothelial progenitor cells (BM-EPCs), and bone marrow-derived mesenchymal stem cells (BM-MSCs), a precursor of pericytes, in KLF5+/- ;Fli-1+/- mice. METHODS Neovascularization and angiogenesis were assessed in KLF5+/- ;Fli-1+/- mice by in vivo Matrigel plug assay and in vitro tube formation assay, respectively. The properties of mouse BM-EPCs and BM-MSCs were assessed with in vitro studies. Dermal vasculature was visualized in vivo by injecting the mice with fluorescein isothiocyanate-conjugated dextran. RESULTS Neovascularization was diminished in skin-embedded Matrigel plugs from KLF5+/- ;Fli-1+/- mice. DMECs from KLF5+/- ;Fli-1+/- mice showed defective tubulogenic activity, decreased expression of VE-cadherin and CD31, and an imbalance in the expression of Notch1/Dll4, suggesting that angiogenesis and anastomosis are disturbed. KLF5+/- ;Fli-1+/- mouse BM-MSCs exhibited enhanced proliferation and migration and increased collagen production following stimulation with transforming growth factor β1, indicating that these cells differentiate preferentially into myofibroblasts rather than pericytes. KLF5+/- ;Fli-1+/- mouse BM-EPCs displayed a transition toward mesenchymal cells, suggesting that vasculogenesis is impaired. Wound healing was delayed in KLF5+/- ;Fli-1+/- mice (mean ± SD healing time 15.67 ± 0.82 days versus 13.50 ± 0.84 days; P = 0.0017), and the vascular network was poorly developed in wound scar tissue. CONCLUSION The characteristics observed in the KLF5+/- ;Fli-1+/- mouse model - specifically, impaired neovascularization and vascular maturation - are similar to those observed in human SSc, and could be at least partially attributable to the induction of SSc-like properties in DMECs, BM-EPCs, and BM-MSCs. These findings indicate the critical contribution of Klf5 and Fli1 deficiency in vascular cells and related cell precursors to the development of SSc vasculopathy.

Abstract
Traumatic soft tissue defects such as bedsores, chronic skin ulcers, limb necrosis, osteonecrosis and other ischemic orthopedic diseases are the most clinically intractable and common problems in orthopedics due to unsatisfactory conventional treatments. The present study designed poly(ethylene glycol; PEG) hydrogels with covalently binded arginylglycylaspartic acid (RGD). Endothelial progenitor cells (EPCs) were encapsulated in the modified hydrogel along with vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF). Results demonstrated that the modified hydrogel displayed good mechanical properties appropriate for a sustained release carrier. RGD modification significantly promoted EPC biocompatibility. VEGF and bFGF encapsulation enhanced the adhesion of EPCs, promoted the production of extracellular matrix and facilitated EPC proliferation. In addition, bFGF and VEGF induced angiogenesis. The combination of growth factors and EPCs in the hydrogel displayed a strong synergy to improve biocompatibility. The present results provided a potential novel treatment approach for soft tissue defects such as bone exposure, chronic skin ulcers, bedsores, limb necrosis, osteonecrosis and other ischemic diseases.

Abstract
Abstract
Peripheral artery diseases include all arterial diseases with the exception of coronary and aortic involvement, more specifically diseases of the extracranial carotids, upper limb arteries, mesenteric and renal vessels, and last but not least, lower limb arteries. Mononuclear stem cells, harvested from various sites (bone marrow, peripheral blood, mesenchymal cells, adipose-derived stem cells) have been studied as a treatment option for alleviating symptoms in peripheral artery disease, as potential stimulators for therapeutic angiogenesis, thus improving vascularization of the ischemic tissue. The aim of this manuscript was to review current medical literature on a novel treatment method — cell therapy, in patients with various peripheral vascular diseases, including carotid, renal, mesenteric artery disease, thromboangiitis obliterans, as well as upper and lower limb artery disease.

Abstract
Bone marrow mononuclear cell (BM-MNC) therapy has emerged as a potential therapy for the treatment of stroke. We performed a systematic review of published studies using BM-MNC therapy in patients with ischaemic stroke (IS). Literature was searched using MEDLINE, PubMed, EMBASE, Trip Database, Cochrane library and clinicaltrial.gov to identify studies on BM-MNC therapy in IS till June, 2016. Data were extracted independently by two reviewers. STATA version 13 was used for carrying out meta-analysis. We included non-randomized open-label, single-arm and non-randomized comparative studies or randomized controlled trials (RCTs) if BM-MNCs were used to treat patients with IS in any phase after the index stroke. One randomized trial, two non-randomized comparative trials and four single-arm open-label trials (total seven studies) involving 227 subjects (137 patients and 90 controls) were included in the systematic review and meta-analysis. The pooled proportion for favourable clinical outcome (modified Rankin Scale score ≤2) in six studies involving 122 subjects was 29% (95% CI 0.16-0.43) who were exposed to BM-MNCs and pooled proportion for favourable clinical outcome of 69 subjects (taken from two trials) who did not receive BM-MNCs was 20% (95% CI 0.12-0.32). The pooled difference in the safety outcomes was not significant between both the groups. Our systematic review suggests that BM-MNC therapy is safe up to 1 year post-intervention and is feasible; however, its efficacy in the case of IS patients is debatable. Well-designed randomized controlled trials are required to provide more information on the efficacy of BM-MNC transplantation in patients with IS.

Abstract
The spontaneous immortalization of cells in vitro is a rare event requiring genomic instability, such as alterations in chromosomes and mutations in genes. In the present study, we report a spontaneously immortalized liver sinusoidal endothelial cell (LSEC) line generated from mouse liver. These immortalized LSECs showed typical LSEC characteristics with the structure of transcellular fenestrations, the expression of von Willebrand factor (VWF) and the ability to uptake DiI-acetylated-low density lipoprotein (DiI-Ac-LDL). However, these immortalized LSECs lost the ability to form capillary-like structures, and showed clonal and multilayer growth without contact inhibition. Moreover, their proliferation rate increased with the increase in the number of passages. In addition, these cells obained the expression of CD31 and desmin, and showed an upregulation of p53 protein expression; however, their karyotype was normal, and they could not form colonies in soft agar or tumors in SCID mice. In conclusion, in the present study, we successfully established a spontaneously immortalized LSEC line.

Abstract
Bone marrow cells for the treatment of ischemic brain injury may depend on the secretion of a large number of neurotrophic factors. Bone marrow regenerative cells are capable of increasing the secretion of neurotrophic factors. In this study, after tail vein injection of 5-fluorouracil for 7 days, bone marrow cells and bone marrow regenerative cells were isolated from the tibias and femurs of rats, and then administered intravenously via the tail vein after focal cerebral ischemia. Immunohistological staining and reverse transcription-PCR detection showed that transplanted bone marrow cells and bone marrow regenerative cells could migrate and survive in the ischemic regions, such as the cortical and striatal infarction zone. These cells promote vascular endothelial cell growth factor mRNA expression in the ischemic marginal zone surrounding the ischemic penumbra of the cortical and striatal infarction zone, and have great advantages in promoting the recovery of neurological function, reducing infarct size and promoting angiogenesis. Bone marrow regenerative cells exhibited stronger neuroprotective effects than bone marrow cells. Our experimental findings indicate that bone marrow regenerative cells are preferable over bone marrow cells for cell therapy for neural regeneration after cerebral ischemia. Their neuroprotective effect is largely due to their ability to induce the secretion of factors that promote vascular regeneration, such as vascular endothelial growth factor.

Abstract
Stroke is a disease of the elderly. However, most of the preclinical studies about the treatment of stroke with bone marrow-derived cells have used young animals. Here, it was assessed whether the sensorimotor recovery promoted by the treatment of the brain ischemia with the bone marrow mononuclear cells (BMMCs) is influenced by age and/or gender. Unilateral cortical ischemia by thermocoagulation was made in the primary motor and sensorimotor cortices in young and middle-aged rats of both genders. Twenty four hours after ischemia, animals received intravenous injection of BMMCs or vehicle. Each combination of age and gender received BMMCs from donor with the same combination. Survival rate and ischemic lesion size were quantified. Sensorimotor recovery was evaluated by the cylinder and adhesive tests. The results showed that the treatment with BMMCs resulted in sensorimotor recovery of both young and middle-aged ischemic rats. No important effect of gender was found, but age was a significant factor. Middle-aged animals had increased mortality and lesion sizes. In the adhesive test, middle-aged animals had lower BMMCs-induced sensorimotor recovery. The results suggest that the treatment of stroke with the BMMCs should be beneficial for males and females in the elderly.

Abstract
Background. Radiotherapy is commonly used to treat breast and thoracic cancers but it also causes delayed microvascular damage and increases the risk of cardiac mortality. Endothelial cell proliferation and revascularization are crucial to restore microvasculature damage and maintain function of the irradiated heart. We have therefore examined the potential of bone marrow-derived endothelial progenitor cells (BM-derived EPCs) for restoration of radiation-induced microvascular damage. Material & Methods. 16 Gy was delivered to the heart of adult C57BL/6 mice. Mice were injected with BM-derived EPCs, obtained from Eng(+/+) or Eng(+/-) mice, 16 weeks and 28 weeks after irradiation. Morphological damage was evaluated at 40 weeks in transplanted mice, relative to radiation only and age-matched controls. Results. Cardiac irradiation decreased microvascular density and increased endothelial damage in surviving capillaries (decrease alkaline phosphatase expression and increased von Willebrand factor). Microvascular damage was not diminished by treatment with BM-derived EPCs. However, BM-derived EPCs from both Eng(+/+) and Eng(+/-) mice diminished radiation-induced collagen deposition. Conclusion. Treatment with BM-derived EPCs did not restore radiation-induced microvascular damage but it did inhibit fibrosis. Endoglin deficiency did not impair this process.

Abstract
Endothelial progenitor cell (EPC) transplantation induces the formation of new blood-vessel networks to supply nutrients and oxygen, and is feasible for the treatment of ischemia and cardiovascular diseases. However, the role of EPCs as a source of proangiogenic cytokines and consequent generators of an extracellular growth factor microenvironment in three-dimensional (3D) microvessel formation is not fully understood. We focused on the contribution of EPCs as a source of proangiogenic cytokines on 3D microvessel formation using an in vitro 3D network model. To create a 3D network model, EPCs isolated from rat bone marrow were sandwiched with double layers of collagen gel. Endothelial cells (ECs) were then cultured on top of the upper collagen gel layer. Quantitative analyses of EC network formation revealed that the length, number, and depth of the EC networks were significantly enhanced in a 3D model with ECs and EPCs compared to an EC monoculture. In addition, conditioned medium (CM) from the 3D model with ECs and EPCs promoted network formation compared to CM from an EC monoculture. We also confirmed that EPCs secreted vascular endothelial growth factor (VEGF). However, networks cultured with the CM were shallow and did not penetrate the collagen gel in great depth. Therefore, we conclude that EPCs contribute to 3D network formation at least through indirect incorporation by generating a local VEGF gradient. These results suggest that the location of EPCs is important for controlling directional 3D network formation in the field of tissue engineering.

Abstract
Ex vivo expansion of endothelial progenitor cells (EPCs) may be a promising strategy to overcome the clinical problem of limited cell numbers. As the culture medium is the key for the cell characteristics, the effects of different culture media on EPCs were investigated in the present study. Rat bone marrow mononuclear cells were cultured in different media, including M-199 media with 20% fetal bovine serum (FBS) and bovine pituitary extract (M1); M-199 media with 10% FBS, 20 ng/ml vascular endothelial growth factor (VEGF) and 10 ng/ml basic fibroblast growth factor (bFGF; M2) or epidermal growth medium (EGM)-2MV media. The cell morphology and biological functions, such as proliferation, adhesion, migration, tube formation and nitric oxide (NO) production were subsequently assayed in vitro. Moreover, endothelial biomarkers and apoptosis were also analyzed. The results showed that endothelial‑like cells appeared in all of the culture systems. First‑passage cells, namely early EPCs, tended to form colonies in M2 and EGM-2MV media but showed a fusiform shape in M1 media. The 3rd or 4th generation EPCs, namely late EPCs, cultured in EGM-2MV media exhibited increased adhesion, migration, tube formation and NO production as compared with EPCs in M1 or M2 media. Furthermore, late EPCs cultured in EGM-2MV expressed higher levels of endothelial cell markers, such as von Willibrand factor (vWF)and CD31, but relatively greater levels of apoptosis were observed. In conclusion, cell culture conditions, for example the medium used, affects the biological properties of bone marrow-derived early and late EPCs.

Abstract
Circulating endothelial progenitor cells (EPCs) in the peripheral blood (PB) have physiological roles in the maintenance of the existing vascular beds and rescue of vascular injury. In this study, we have evaluated the properties of Lin⁻/VEGF-R2⁺ progenitor cells isolated from the mouse bone marrow (BM) and further studied their distribution and integration in an animal model of laser-induced retinal vascular injury. Lin⁻/VEGF-R2⁺ cells were enriched from C57BL/6 mice BM using magnetic cell sorting with hematopoietic lineage (Lin) depletion followed by VEGF-R2 positive selection. Lin⁻/VEGF-R2⁺ BM cells were characterized using flow cytometry and immunocytochemistry and further tested for colony formation during culture and tube formation on Matrigel®. Lin⁻/VEGF-R2⁺ BM cells possessed typical EPC properties such as forming cobble-stone shaped colonies after 3 to 4 weeks of culture, CD34⁺ expression, take up of Dil-acLDL and binding to Ulex europaeus agglutinin. However, they did not form tube-like structures on Matrigel®. The progenitor cells retained their phenotype over extended period of culture. After intravitreal transplantation in eyes subjected to the laser-induced retinal vascular injury, some Lin⁻/VEGF-R2⁺ cells were able to integrate into the damaged retinal vasculature but the level of cell integration seemed less efficient when compared with previous reports in which EPCs from the human PB were employed. Our results indicate that Lin⁻/VEGF-R2⁺ cells isolated from the mouse BM share some similarities to EPCs from the human PB but most of them are at a very early stage of maturation and remain quiescent during culture and after intravitreal transplantation.

Abstract
Previous studies have shown sensorimotor recovery by treatment with bone marrow mononuclear cells (BMMCs) after focal brain ischemia. However, sensorimotor tests commonly used are designed to examine motor patterns that do not involve skill or training. We evaluated whether BMMCs treatment was able to recover forelimb skilled movements. Reaching chamber/pellet retrieval (RCPR) task was used, in which animals had to learn to grasp a single food pellet and lead it to its mouth. We also evaluated therapeutic effect of this training on unskilled sensorimotor function. Adult male Wistar rats suffered unilateral cortical ischemia by thermocoagulation in motor and somesthetic primary areas. A day later, they received i.v. injection of 3×10(7) BMMCs or vehicle (saline), forming four experimental groups: BMMCs+RCPR; saline+RCPR; BMMCs and saline. Cylinder and adhesive tests were applied in all experimental groups, and all behavioral tests were performed before and along post-ischemic weeks after induction of ischemia. Results from RCPR task showed no significant difference between BMMCs+RCPR and saline+RCPR groups. In cylinder test, BMMCs-treated groups showed significant recovery, but no significant effect of RCPR training was observed. In adhesive test, BMMCs treatment promoted significant recovery. Synergistic effect was found since only together they were able to accelerate recovery. The results showed that BMMCs treatment promoted increased recovery of unsophisticated sensorimotor function, but not of skilled forepaw movements. Thus, BMMCs might not be able to recover all aspects of sensorimotor functions, although further studies are still needed to investigate this treatment in ischemic lesions with different locations and extensions.

Abstract
Transplantation of autologous bone marrow mononuclear cells (BMMCs) has been proven safe in animal and human studies. However, there are very few studies in stroke patients. In this study, intra-arterial autologous BMMCs were infused in patients with moderate to severe acute middle cerebral artery infarcts. The subjects of this study included 20 patients with early or late spontaneous recanalization but with persistent deficits, in whom treatment could be initiated between 3 and 7 days after stroke onset. Mononuclear cells were isolated from bone marrow aspirates and infused at the proximal middle cerebral artery of the affected hemisphere. Safety analysis (primary endpoint) during the 6-month follow-up assessed death, any serious clinical events, neurological worsening with ≥ 4-point increase in National Institutes of Health Stroke Scale (NIHSS) scores, seizures, epileptogenic activity on electroencephalogram, and neuroimaging complications including new ischemic, hemorrhagic, or neoplastic lesions. Satisfactory clinical improvement (secondary endpoint) at 90 days was defined according to the pretreatment NIHSS scores as follows: modified Rankin Scale score of 0 in patients with NIHSS <8, modified Rankin Scale scores of 0-1 in patients with NIHSS 8-14, or modified Rankin Scale scores 0-2 in patients with NIHSS >14. Good clinical outcome was defined as mRS ≤2 at 90 days. Serial clinical, laboratory, electroencephalogram, and imaging evaluations showed no procedure-related adverse events. Satisfactory clinical improvement occurred in 6/20 (30%) patients at 90 days. Eight patients (40%) showed a good clinical outcome. Infusion of intra-arterial autologous BMMCs appears to be safe in patients with moderate to severe acute middle cerebral artery strokes. No cases of intrahospital mortality were seen in this pilot trial. Larger prospective randomized trials are warranted to assess the efficacy of this treatment approach.

Abstract
AIM Bone marrow endothelial progenitor cells (BMEPCs) are believed to be a promising cell source for regenerative medicine; however, their electrophysiology properties have not been fully clarified, which is important to the clinical application of BMEPCs. The current study was designed to determine the transmembrane ion currents and mRNA expression levels of related ion channel subunits in rat BMEPCs. METHODS Bone marrow mononuclear cells were isolated by density gradient separation and cultured in EPC medium. The transmembrane ion currents were determined using whole-cell patch-voltage clamp technique, and the levels of mRNA and protein expressions of functional ionic channels were measured using RT-PCR and western immunoblot analysis. RESULTS We observed two types of ionic currents in undifferentiated rat BMEPCs. One was Ca(2+) -activated potassium current (I(kca) ), which was seen in approx. 90% of cells when 1 μm Ca(2+) was employed in pipette solution, and it was predominantly inhibited by intermediate-conductance I(kca) inhibitor clotrimazole. The other one was volume-sensitive chloride current (I(cl) ), which was detected in 85.7% of cells when BMEPCs were subjected to K(+) -free hypotonic extracellular solution, whose currents could be inhibited by 5-nitro-2-(3-phenylpropylamino) benzoic acid (NPPB). The corresponding ion channel genes and proteins, KCNN4 for I(kca) and Clcn3 for I(cl) , were confirmed by RT-PCR and western immunoblot analysis of BMEPCs. CONCLUSION Our results demonstrated for the first time that rat BMEPCs expressed intermediate-conductance Ca(2+) -activated potassium currents and volume-sensitive chloride currents, and corresponding genes and proteins of these two channels are KCNN4 and Clcn3 respectively.

Abstract
The use of bone marrow mononuclear cells (BMMCs) has been shown as a putative efficient therapy for stroke. However, the mechanisms of therapeutic action are not yet completely known. Mannose receptor (MR) is a subgroup of the C-type lectin receptor superfamily involved in innate immune response in several tissues. Although known primarily for its immune function, MR also has important roles in cell migration, cell debris clearance and tissue remodeling during inflammation and wound healing. Here we analyzed MR expression in brains of rats one week after induction of unilateral focal cortical ischemia by thermocoagulation in blood vessels of sensorimotor cortex. Additionally, we evaluated possible changes in such expression in cortices of rats subjected to ischemia plus treatment with BMMCs. Our results showed high expression of MR in an unknown GFAP(+) cell type and in phagocytic macrophages/microglia within the lesion boundary zone whereas in the non-injured (contralateral) cortical parenchyma, low levels of MR expression were observed. Moreover, therapy with BMMCs induced overexpression of MR in ipsilateral (injured) cortex. Previous studies from our group have shown functional recovery and decreased neurodegeneration in BMMC-treated rats in the same model of focal cortical ischemia. Thus, we suggest that ischemic injury induces large increase in MR expression as part of a mechanism for clearance of damage-associated molecular patterns (DAMPs). In addition, induction of MR overexpression by BMMCs might increase the efficiency of clearance, being one of the protective mechanisms of these cells.

Abstract
Bone-marrow-derived endothelial progenitor cells (BM-EPCs) contribute to postnatal neovascularization and therefore are of great interest for cell therapies to treat ischemic diseases. However, their origin and characteristics are still in controversy. In this paper, we identified the origin/lineage of the BM-EPCs that were isolated from bone marrow mononuclear cells and differentiated with the induction of bone-marrow endothelial-cellconditioned
medium (ECCM). BM-EPCs were characterized in terms of phenotype, lineage potential, and their functional properties. Endothelial cell colonies derived from BM-EPC were cultured with ECCM for 3 months. Cultured EPC colony cells expressed endothelial cell markers and formed the capillary-like network in vitro. EPC colony cells expressed differential proliferative capacity; some of the colonies exhibited a high proliferative potential (HPP) capacity up to 20 population doublings. More importantly, these HPP-EPCs expressed hematopoietic marker CD45, exhibited endocytic activities, and preserved some of the myeloid cell activity. In addition, the HPP-EPCs secrete various growth factors including VEGF and GM-CSF into the culture medium. The results demonstrate that these EPCs were primarily derived from hematopoietic origin of early precursor cells and maintained high proliferative potential capacity, a feature with a significant potential in the application of cell therapy in ischemic diseases.

Abstract
BACKGROUND & AIMS Cell therapy has been used to attenuate liver injury. Here we evaluated whether genetic engineering of either bone marrow-derived mononuclear cells (MNC) or endothelial progenitor cells (EPC) many enhance their hepatoprotective properties. METHODS Mice with ConA-induced hepatitis or with lethal fulminant hepatitis resulting from administration of an adenovirus encoding CD40L (AdCD40L) received an intra-splenic injection of saline or 2 × 10(6) unmodified MNC or EPC or the same cells transduced ex vivo with an adenovirus expressing luciferase (MNCLUC and EPCLUC) or encoding the hepatoprotective cytokine cardiotrophin-1 (CT-1) (MNCCT-1 and EPCCT-1). We analyzed the extent of liver damage, the intensity of inflammatory reaction, and animal survival. RESULTS Luciferase immunohistochemistry showed that after injection into the spleen, the engineered cells migrated efficiently to the damaged liver. In mice with ConA hepatitis EPCCT-1, but not other forms of cell therapy, significantly decreased serum transaminases and induced more intense histological improvement than other treatments. This superior therapeutic effect was associated with upregulation of cytoprotective molecules including IGF-I and EGF, lower expression of proinflammatory cytokines, IL-1b and TNFα, and decreased granzyme B levels. In AdCD40L-induced lethal fulminant hepatitis, EPCCT-1 also exceeded other cell therapies in attenuating the expression of proinflammatory mediators and hepatic injury enabling 35.7% survival while mortality was 100% in the other treatment groups. CONCLUSIONS Genetic engineering of EPC to overexpress CT-1 enhances the hepatoprotective properties of EPC and constitutes a therapy that deserves consideration for acute liver failure.

Abstract
Bone marrow-derived cells have been postulated as a source of multipotent mesenchymal stem cells (MSC). However, the whole fraction of MSC remains heterogeneous and the expansion of primitive subset of these cells is still not well established. Here, we optimized the protocol for propagating the low-adherent subfraction of MSC which results in long-term expansion of population characterized by CD45(-)CD14(+)CD34(+) phenotype along with expression of common MSC markers. We established that the expanded MSC are capable of differentiating into endothelial cells highly expressing angiogenic markers and exhibiting functional properties of endothelium. Moreover, we found these cells to be multipotent and capable of giving rise into cells from neuronal lineages. Interestingly, the expanded MSC form characteristic cellular spheres in vitro indicating primitive features of these cells. In sum, we isolated the novel multipotent subpopulation of CD45(-)CD14(+) CD34(+) bone marrow-derived cells that could be maintained in long-term culture without losing this potential.

Abstract
PURPOSE to study the feasibility of in vivo MR imaging in evaluation of endothelial progenitor cells (EPCs) on the progress of neointimal hyperplasia after carotid artery injury in mice. METHODS fifteen Kunming mice were injured in left carotid artery by removal of endothelium with a flexible wire 7 days after splenectomy. EPCs were collected by in vitro culture of spleen-derived mouse mononuclear cells (MNCs) in endothelial basal medium. After artery injury, the mice received EPCs (n= 6), phosphate buffered solution (PBS) (n= 6), and DiI-Ac-LDL labeled EPCs (n= 3) intravenously. In vivo serial MR imaging were performed at different time points after artery injury, and vessel-wall thickness and vessel-wall area at injury site were measured on MR imaging. RESULTS transfused Dil-Ac-LDL-labeled EPCs were found at the injury site by histopathological analyses. Vessel wall of injured artery was observed and quantitatively analyzed with MR imaging. Vessel-wall thickness was .487 ± .122 mm in the non-EPCs transfusion group and .294 ± .051 mm in the EPCs transfusion group 15 days after artery injury (P= .005). While vessel-wall area was .860 ± .182 mm(2) in the non-EPCs transfusion group and .468 ± .141 mm(2) in the EPCs transfusion group 15 days after artery injury (P= .002). Therefore, the neointimal hyperplasia of injured artery in the EPCs transfusion group was lesser than that in the non-EPCs transfusion group. CONCLUSION neointimal hyperplasia can be reduced by intravenous transfusion of EPCs and analyzed on in vivo MR imaging after vascular injury.

Abstract
Increasing evidence shows that administration of bone marrow mononuclear cells (BMMCs) is a potential treatment for various ischemic diseases, such as ischemic stroke. Although angiogenesis has been considered primarily responsible for the effect of BMMCs, their direct contribution to endothelial cells (ECs) by being a functional elements of vascular niches for neural stem/progenitor cells (NSPCs) has not been considered. Herein, we examine whether BMMCs affected the properties of ECs and NSPCs, and whether they promoted neurogenesis and functional recovery after stroke. We compared i.v. transplantations 1 x 10(6) BMMCs and phosphate-buffered saline in mice 2 days after cortical infarction. Systemically administered BMMCs preferentially accumulated at the postischemic cortex and peri-infarct area in brains; cell proliferation of ECs (angiogenesis) at these regions was significantly increased in BMMCs-treated mice compared with controls. We also found that endogenous NSPCs developed in close proximity to ECs in and around the poststroke cortex and that ECs were essential for proliferation of these ischemia-induced NSPCs. Furthermore, BMMCs enhanced proliferation of NSPCs as well as ECs. Proliferation of NSPCs was suppressed by additional treatment with endostatin (known to inhibit proliferation of ECs) following BMMCs transplantation. Subsequently, neurogenesis and functional recovery were also promoted in BMMCs-treated mice compared with controls. These results suggest that BMMCs can contribute to the proliferation of endogenous ischemia-induced NSPCs through vascular niche regulation, which includes regulation of endothelial proliferation. In addition, these results suggest that BMMCs transplantation has potential as a novel therapeutic option in stroke treatment.

Abstract
OBJECTIVES The aim of this study was to determine an optimal culture method for porcine bone marrow-derived endothelial progenitor cells (EPCs). MATERIALS AND METHODS Mononuclear cells (MNCs) were isolated by density centrifugation and differentiated into EPCs in in vitro. At first-passage, EPCs were cultured at different cell densities (5 x 10(3), 1 x 10(4), 2 x 10(4) or 5 x 10(4)/cm(2)) and in basic medium (EGM, medium 199, DMEM or 1640) supplemented with FBS (2%, 5%, 10% or 20%) and different combinations of cytokines (VEGF, VEGF + bFGF, VEGF + bFGF + EGF, or VEGF + bFGF + EGF + IGF), the experiment being based on L(64) (4(21)) orthogonal design. RESULTS AND CONCLUSIONS This demonstrated that the optimal culture method for our EPCs displayed higher expansion and migration rates as compared to other groups, by analysis of variance; that is, cultured at 1 x 10(4)/cm(2) in M199 supplemented with 10% FBS and VEGF + bFGF + IGF + EGF. Furthermore, percentage of positive cells stained by Dil-ac-LDL and FITC-UEA-1 was more than 65%, and as shown by immunohistochemistry, these cells also stained positively for CD133, CD34 and KDR. The present study indicates that the number and function of porcine EPCs significantly increased when using our optimized culture parameters.

Abstract
OBJECTIVE The impact of diabetes on the bone marrow (BM) microenvironment was not adequately explored. We investigated whether diabetes induces microvascular remodeling with negative consequence for BM homeostasis. METHODS AND RESULTS We found profound structural alterations in BM from mice with type 1 diabetes with depletion of the hematopoietic component and fatty degeneration. Blood flow (fluorescent microspheres) and microvascular density (immunohistochemistry) were remarkably reduced. Flow cytometry verified the depletion of MECA-32(+) endothelial cells. Cultured endothelial cells from BM of diabetic mice showed higher levels of oxidative stress, increased activity of the senescence marker beta-galactosidase, reduced migratory and network-formation capacities, and increased permeability and adhesiveness to BM mononuclear cells. Flow cytometry analysis of lineage(-) c-Kit(+) Sca-1(+) cell distribution along an in vivo Hoechst-33342 dye perfusion gradient documented that diabetes depletes lineage(-) c-Kit(+) Sca-1(+) cells predominantly in the low-perfused part of the marrow. Cell depletion was associated to increased oxidative stress, DNA damage, and activation of apoptosis. Boosting the antioxidative pentose phosphate pathway by benfotiamine supplementation prevented microangiopathy, hypoperfusion, and lineage(-) c-Kit(+) Sca-1(+) cell depletion. CONCLUSIONS We provide novel evidence for the presence of microangiopathy impinging on the integrity of diabetic BM. These discoveries offer the framework for mechanistic solutions of BM dysfunction in diabetes.

Abstract
Intervention in the RAAS (renin-angiotensin-aldosterone system) is one of the leading pharmacotherapeutic strategies, among others, used for the treatment of cardiovascular disease to improve the prognosis after myocardial infarction and to reduce hypertension. Recently, regenerative progenitor cell therapy has emerged as a possible alternative for pharmacotherapy in patients after myocardial infarction or ischaemic events elsewhere, e.g. in the limbs. Angiogenic cell therapy to restore the vascular bed in ischaemic tissues is currently being tested in a multitude of clinical studies. This has prompted researchers to investigate the effect of modulation of the RAAS on progenitor cells. Furthermore, the relationship between hypertension and endothelial progenitor cell function is being studied. Pharmacotherapy by means of angiotensin II type 1 receptor antagonists or angiotensin-converting enzyme inhibitors has varying effects on progenitor cell levels and function. These controversial effects may be explained by involvement of multiple mediators, e.g. angiotensin II and angiotensin-(1-7), that have differential effects on mesenchymal stem cells, haematopoietic progenitor cells and endothelial progenitor cells. Importantly, angiotensin II can either stimulate endothelial progenitor cells by improvement of vascular endothelial growth factor signalling, or invoke excessive production of reactive oxygen species causing premature senescence of these cells. On the other hand, angiotensin-(1-7) stimulates haematopoietic cells and possibly also endothelial progenitor cells. Furthermore, aldosterone, bradykinin and Ac-SDKP (N-acetyl-Ser-Asp-Lys-Pro) may also affect progenitor cell populations. Alternatively, the variability in effects of angiotensin II type 1 receptor and angiotensin-converting enzyme inhibition on cardiovascular progenitor cells might reflect differences between the various models or diseases with respect to circulating and local tissue RAAS activation. In the present review we discuss what is currently known with respect to the role of the RAAS in the regulation of cardiovascular progenitor cells.

Treatment with bone marrow mononuclear cells induces functional recovery and decreases neurodegeneration after sensorimotor cortical ischemia in rats. Brain Res 2009; 1266:108-20.

Abstract
We evaluated the beneficial effect of treatment with bone marrow mononuclear cells(BMMC) in a rat model of focal ischemia induced by thermocoagulation of the blood vessels in the left sensorimotor cortex. BMMC were obtained from donor rats and injected into the femoral vein one day after ischemia. BMMC-treated animals received approx. 3×10⁷ cells and control animals received PBS. Animals were evaluated for functional sensorimotor recovery weekly with behavioral tests and for changes in neurodegeneration and structural plasticity with histochemical and immunostaining techniques, respectively. The BMMC-treated group showed a significant recovery of function in the cylinder test 14, 21 and 28 days after ischemia. In the beam test, both groups showed improvement, with a tendency for faster recovery in the BMMC-treated group. In the adhesive test, both groups did not show significant recovery of function. FJC+ cell counting revealed significant decrease in the neurodegeneration in the periphery of the lesion in the BMMC-treated group. The analyses by immunoblotting revealed no significant difference in the expression of GAP-43 and synaptophysin between the groups. Thus, our results showed beneficial effects of the treatment with BMMC, which promoted significant functional recovery and decreased neurodegeneration. These results suggest that the therapy with BMMC is effective and might be a protocol of treatment for stroke in humans, alternative to the therapy proposed with the bone marrow-derived mesenchymal stem cells.

Abstract
Endothelial progenitor cells (EPCs) are derived from the bone marrow (BM) and peripheral blood (PB), contributing to tissue repair in various pathological conditions via the formation of new blood vessels, that is, neovascularization. EPCs can be mobilized into the circulation in response to growth factors and cytokines released following stimuli such as vascular trauma, wounding and cancer. EPCs are involved in vasculogenesis during embryogenesis, but are now recognized to have a significant bearing upon disease outcome through their contribution to neovascularization in a variety of pathological states in adulthood. EPCs exist in very small numbers, especially in circulating blood in adults where they only account for 0.01% of all cells. We discuss the contribution and potential therapeutic applications of EPCs in disease, also noting the prognostic value of PB EPC numbers, especially in heart disease and cancer.

Abstract
OBJECTIVE To test whether the GM-CSF accelerates the proliferation of bone marrow endothelial progenitor cells (BM EPCs). METHODS BM EPCs were induced by endothelial cell conditioned medium (EC-CM). The effect of different concentrations of GM-CSF on the proliferation of BM EPCs was evaluated by the formation of EC-cols, MTT assay, and cell cycle assay. The single progenitor cell growth curves were quantified. RESULTS The data indicated that GM-CSF accelerated the proliferation of BM EPCs both in colony numbers and colony size. MTT confirmed the effect of GM-CSF on accelerating the proliferation of BM EPCs. The single colony experiments showed that EC-cols expressed different proliferation capacity, suggesting that the EC-cols with different proliferation potentials might have been derived from different levels of immature progenitors. The cell cycle assay showed that the rate of cells entering into S phase was 9.3% in the group treated with GM-CSF and 2.1% in the controls. Furthermore, these cells displayed the specific endothelial cell markers and formed capillary-like structures. CONCLUSIONS GM-CSF accelerates proliferation of BM EPCs. The potential beneficial of GM-CSF in the application of treating vascular ischemic patients is promising.
