Abstract
BACKGROUND Alveolar echinococcosis (AE) is a lethal zoonosis caused by the fox tapeworm Echinococcus multilocularis. The disease is difficult to treat, and an effective therapeutic drug is urgently needed. Echinococcus multilocularis-associated angiogenesis is required by the parasite for growth and metastasis; however, whether antiangiogenic therapy is effective for treating AE is unclear. METHODS The in vivo efficacy of sunitinib malate (SU11248) was evaluated in mice by secondary infection with E. multilocularis. Enzyme-linked immunosorbent assays (ELISAs) were used to evaluate treatment effects on serum IL-4 and vascular endothelial growth factor A (VEGFA) levels after SU11248 treatment. Gross morphological observations and immunohistochemical staining were used to evaluate the impact of SU11248 on angiogenesis and the expression of pro-angiogenic factors VEGFA and VEGF receptor 2 (VEGFR2) in the metacestode tissues. Furthermore, the anthelmintic effects of SU11248 were tested on E. multilocularis metacestodes in vitro. The effect of SU11248 on the expression of VEGFA, VEGFR2, and phosphorylated VEGFR2 (p-VEGFR2) in liver cells infected with protoscoleces in vitro was detected by western blotting, reverse transcription quantitative polymerase chain reaction (RT-qPCR), and enzyme-linked immunosorbent assay (ELISA). The influence of SU11248 on endothelial progenitor cell (EPC) proliferation and migration was determined using CCK8 and transwell assays. RESULTS In vivo, SU11248 treatment markedly reduced neovascular lesion formation and substantially inhibited E. multilocularis metacestode growth in mice. Further, it exhibited high anti-hydatid activity as efficiently as albendazole (ABZ), and the treatment resulted in reduced protoscolex development. In addition, VEGFA, VEGFR2, and p-VEGFR2 expression was significantly decreased in the metacestode tissues after SU11248 treatment. However, no effect of SU11248 on serum IL-4 levels was observed. In vitro, SU11248 exhibited some anthelmintic effects and damaged the cellular structure in the germinal layer of metacestodes at concentrations below those generally considered acceptable for treatment (0.12-0.5 μM). Western blotting, RT-qPCR, and ELISA showed that in co-cultured systems, only p-VEGFR2 levels tended to decrease with increasing SU11248 concentrations. Furthermore, SU11248 was less toxic to Reuber rat hepatoma (RH) cells and metacestodes than to EPCs, and 0.1 μM SU11248 completely inhibited EPC migration to the supernatants of liver cell and protoscolex co-cultures. CONCLUSIONS SU11248 is a potential candidate drug for the treatment of AE, which predominantly inhibits parasite-induced angiogenesis. Host-targeted anti-angiogenesis treatment strategies constitute a new avenue for the treatment of AE.

Abstract
Crosstalk between nerves and bone is essential for bone repair, for which Schwann cells (SCs) are crucial in the regulation of the microenvironment. Considering that exosomes are critical paracrine mediators for intercellular communication that exert important effects in tissue repair, the aim of this study is to confirm the function and molecular mechanisms of Schwann cell-derived exosomes (SC-exos) on bone regeneration and to propose engineered constructs that simulate SC-mediated nerve-bone crosstalk. SCs promoted the proliferation and differentiation of bone marrow mesenchymal stem cells (BMSCs) through exosomes. Subsequent molecular mechanism studies demonstrated that SC-exos promoted BMSC osteogenesis by regulating the TGF-β signaling pathway via let-7c-5p. Interestingly, SC-exos promoted the migration and tube formation performance of endothelial progenitor cells. Furthermore, the SC-exos@G/S constructs were developed by bioprinting technology that simulated SC-mediated nerve-bone crosstalk and improved the bone regeneration microenvironment by releasing SC-exos, exerting the regulatory effect of SCs in the microenvironment to promote innervation, vascularization, and osteogenesis and thus effectively improving bone repair in a cranial defect model. This study demonstrates the important role and underlying mechanism of SCs in regulating bone regeneration through SC-exos and provides a new engineered strategy for bone repair.

Abstract
Heterogeneity of endothelial cell (EC) populations reflects their diverse functions in maintaining tissue's homeostasis. However, their phenotypic, molecular, and functional properties are not entirely mapped. We use the Tie2-CreERT2;Rosa26-tdTomato reporter mouse to trace, profile, and cultivate primary ECs from different organs. As paradigm platform, we use this strategy to study bone marrow endothelial cells (BMECs). Single-cell mRNA sequencing of primary BMECs reveals that their diversity and native molecular signatures is transitorily preserved in an ex vivo culture that conserves key cell-to-cell microenvironment interactions. Macrophages sustain BMEC cellular diversity and expansion and preserve sinusoidal-like BMECs ex vivo. Endomucin expression discriminates BMECs in populations exhibiting mutually exclusive properties and distinct sinusoidal/arterial and tip/stalk signatures. In contrast to arterial-like, sinusoidal-like BMECs are short-lived, form 2D-networks, contribute to in vivo angiogenesis, and support hematopoietic stem/progenitor cells in vitro. This platform can be extended to other organs' ECs to decode mechanistic information and explore therapeutics.

Abstract
Cell-based therapeutics bring great hope in areas of unmet medical needs. Mesenchymal stem cells (MSCs) have been suggested to facilitate neovascularization mainly by paracrine action. Endothelial progenitor cells (EPCs) can migrate to ischemic sites and participate in angiogenesis. The combination cell therapy that includes MSCs and EPCs has a favorable effect on ischemic limbs. However, the mechanism of combination cell therapy remains unclear. Herein, we investigate whether stromal cell-derived factor (SDF)-1 secreted by MSCs contributes to EPC migration to ischemic sites via CXCR4/Phosphoinositide 3-Kinases (PI3K)/protein kinase B (termed as AKT) signaling pathway. First, by a "dual-administration" approach, intramuscular MSC injections were supplemented with intravenous Qdot® 525 labeled-EPC injections in the mouse model of hind limb ischemia. Then, the mechanism of MSC effect on EPC migration was detected by the transwell system, tube-like structure formation assays, western blot assays in vitro. Results showed that the combination delivery of MSCs and EPCs enhanced the incorporation of EPCs into the vasculature and increased the capillary density in mouse ischemic hind limb. The numbers of CXCR4-positive EPCs increased after incubation with MSC-conditioned medium (CM). MSCs contributed to EPC migration and tube-like structure formation, both of which were suppressed by AMD3100 and wortmannin. Phospho-AKT induced by MSC-CM was attenuated when EPCs were pretreated with AMD3100 and wortmannin. In conclusion, we confirmed that MSCs contributes to EPC migration, which is mediated via CXCR4/PI3K/AKT signaling pathway.

Abstract
Endothelial progenitor cells (EPCs) have been broadly studied for several years due to their outstanding regenerative potential. Moreover, these cells might be a valuable source of genetic information for the preservation of endangered animal species. However, a controversy regarding their characterization still exists. The aim of this study was to isolate and compare the rabbit peripheral blood- and bone marrow-derived EPCs with human umbilical vein endothelial cells (HUVECs) in terms of their phenotype and morphology that could be affected by the passage number or cryopreservation as well as to assess their possible neuro-differentiation potential. Briefly, cells were isolated and cultured under standard endothelial conditions until passage 3. The morphological changes during the culture were monitored and each passage was analyzed for the typical phenotype using flow cytometry, quantitative real–time polymerase chain reaction (qPCR) and novel digital droplet PCR (ddPCR), and compared to HUVECs. The neurogenic differentiation was induced using a commercial kit. Rabbit cells were also cryopreserved for at least 3 months and then analyzed after thawing. According to the obtained results, both rabbit EPCs exhibit a spindle-shaped morphology and high proliferation rate. The both cell lines possess same stable phenotype: CD14−CD29+CD31−CD34−CD44+CD45−CD49f+CD73+CD90+CD105+CD133−CD146−CD166+VE-cadherin+VEGFR-2+SSEA-4+MSCA-1−vWF+eNOS+AcLDL+ALDH+vimentin+desmin+α-SMA+, slightly different from HUVECs. Moreover, both induced rabbit EPCs exhibit neuron-like morphological changes and expression of neuronal markers ENO2 and MAP2. In addition, cryopreserved rabbit cells maintained high viability (>85%) and endothelial phenotype after thawing. In conclusion, our findings suggest that cells expanded from the rabbit peripheral blood and bone marrow are of the endothelial origin with a stable marker expression and interesting proliferation and differentiation capacity.

Abstract
Traumatic injuries are a leading cause of death and disability in both military and civilian populations. Given the complexity and diversity of traumatic injuries, novel and individualized treatment strategies are required to optimize outcomes. Cellular therapies have potential benefit for the treatment of acute or chronic injuries, and various cell-based pharmaceuticals are currently being tested in preclinical studies or in clinical trials. Cellular therapeutics may have the ability to complement existing therapies, especially in restoring organ function lost due to tissue disruption, prolonged hypoxia or inflammatory damage. In this article we highlight the current status and discuss future directions of cellular therapies for the treatment of traumatic injury. Both published research and ongoing clinical trials are discussed here.

Abstract
Objective To investigate the effect of echinococcus granulosus protoscolices on the differentiation of bone marrow mesenchymal stem cells (BMSCs) into fibroblasts. Methods Femur bone marrow of 4-week-old C57BL/6 mice was taken and BMSCs were isolated and cultured by adherent culture. Echinococcus granulosus protoscolices was extracted from the liver of sheep infected with echinococcus granulosus. The experiment was divided into two groups. The experimental group was co-cultured with the 3rd generation BMSCs and the echinococcus granulosus protoscolices, and the control group was the 3rd generation BMSCs. Before and after co-culture, the morphology of BMSCs and the activity of echinococcus granulosus protoscolices were observed by inverted microscope. After cultured for 1, 3, 5, and 7 days, the mRNA expressions of transforming growth factor β 1 (TGF-β 1), collagen type Ⅰ, and collagen type Ⅲ were detected by real-time fluorescent quantitative PCR, the protein expressions of TGF-β 1, collagen type Ⅰ, collagen type Ⅲ, Smad7, and phosphorylated Smad2/3 were detected by Western blot, and the contents of collagen type Ⅰ and collagen type Ⅲ in the supernatant of the two groups were detected by ELISA. Results After 7 days of co-culture, the morphology of BMSCs changed into fusiform and irregular triangle, which was closer to the mouse fibroblasts. The relative mRNA expressions of TGF-β 1, collagen type Ⅰ, and collagen type Ⅲ in the experimental group were significantly higher than those in the control group; the relative protein expressions of TGF-β 1, collagen type Ⅰ, collagen type Ⅲ, and phosphorylated Smad2/3 in the experimental group were significantly higher than those in the control group, and the relative protein expression of Smad7 in the experimental group was significantly lower than that in the control group; the contents of collagen type Ⅰ and collagen type Ⅲ in the supernatant of the experimental group were significantly higher than those in the control group. The differences between the two groups were significant ( P<0.05). Conclusion Echinococcus granulosus protoscolices may promote the secretion of collagen type Ⅰ, collagen type Ⅲ, and TGF-β 1 by TGF-β 1/Smad signal pathway, which can promote the fibrosis of BMSCs that related to the formation of fibrocystic wall by echinococcosis.

Abstract
As the impairment of myocardial microenvironments due to coronary
microembolization (CME) compromises the treatment effect of percutaneous
coronary intervention and leads to adverse prognosis, we hypothesized that
endothelial progenitor cells (EPCs) transplantation could improve cardiac
function in the condition of CME. Low- (2 × 105) and high- (2 × 106) dose rat bone
marrow-derived EPCs were transplanted in a model of CME. To develop a CME model,
rats were injected with autologous micro-blood-clots into the left ventricle.
Echocardiograph was examined before and 1, 7, and 28 days after EPC
transplantation; serum cardiac troponin I (cTNI), von Willebrand factor (vWF),
and cardiac microRNA expression were examined one day after EPCs
transplantation. Heart morphology and vascular endothelial growth factor (VEGF),
vWF, and basic fibroblast growth factor (bFGF) expression were examined one day
after EPC transplantation. After 10 days of culture inductions, BM-EPCs have high purity as confirmed by
flow cytometry. Cardiac function reflected by left ventricular ejection fraction
significantly decreased after CME treatment and rescued by low-dose EPC.
Compared to the sham group, cTNI and vWF serum levels increased significantly
after CME treatment and rescued by low-dose EPC and high-dose EPC. Low-dose EPC
treatment decreased myocardial necrosis and fibrosis and elevated cardiac
expression of VEGF and vWF, while decreasing the cardiac expression of bFGF.
Low-dose EPC treatment significantly suppressed cardiac expression of
microRNA-19a but significantly enhanced microRNA-21, microRNA-214, and
microRNA-486-3p expression. In conclusion, our results indicate that low-dose
EPC transplantation may play a proangiogenic, antifibroblast, antifibrosis, and
antinecrosis role and enhance cardiac function in a rat model of CME through a
microRNA-related pathway.

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.
