Abstract
This study analyzed the effect of bone marrow mesenchymal stem cells (BMSC) homing with chemotaxis transplantation of SDF-1a on the repair of corneal damage. The SDF-1a with varied concentration was added. They were divided into A group, B group, C group, D group and control group followed
by analysis of corneal cell survival by MTT, apoptosis by flow cytometry, and Trkb level by immunohistochemical staining. There was an increasing tendency on the quantity of chemotactic cells (P <0.05) with a highest quantity in C group. The recruitment of BMSC could be prompted
by SDF-1a and the chemotactic effect was the best when SDF-1a concentration was 100 ng/ml. The survival rate and Trkb protein level in experimental groups was higher than that in control group with highest survival rate and Trkb level in C group. In conclusion, corneal injury repair is prompted
by BMSC homing with chemotaxis transplantation of SDF-1a, indicating that it might be used as a novel approach to promote corneal injury repair.

Unraveling the potential of endothelial progenitor cells as a treatment following ischemic stroke. Front Neurol 2022; 13:940682.

Abstract
Ischemic stroke is becoming one of the most common causes of death and disability in developed countries. Since current therapeutic options are quite limited, focused on acute reperfusion therapies that are hampered by a very narrow therapeutic time window, it is essential to discover novel treatments that not only stop the progression of the ischemic cascade during the acute phase, but also improve the recovery of stroke patients during the sub-acute or chronic phase. In this regard, several studies have shown that endothelial progenitor cells (EPCs) can repair damaged vessels as well as generate new ones following cerebrovascular damage. EPCs are circulating cells with characteristics of both endothelial cells and adult stem cells presenting the ability to differentiate into mature endothelial cells and self-renew, respectively. Moreover, EPCs have the advantage of being already present in healthy conditions as circulating cells that participate in the maintenance of the endothelium in a direct and paracrine way. In this scenario, EPCs appear as a promising target to tackle stroke by self-promoting re-endothelization, angiogenesis and vasculogenesis. Based on clinical data showing a better neurological and functional outcome in ischemic stroke patients with higher levels of circulating EPCs, novel and promising therapeutic approaches would be pharmacological treatment promoting EPCs-generation as well as EPCs-based therapies. Here, we will review the latest advances in preclinical as well as clinical research on EPCs application following stroke, not only as a single treatment but also in combination with new therapeutic approaches.

Ginkgolide B Targets and Inhibits Creatine Kinase B to Regulate the CCT/TRiC-SK1 Axis and Exerts Pro-Angiogenic Activity in Middle Cerebral Artery Occlusion Mice. Pharmacol Res 2022; 180:106240.

Abstract
Promoting angiogenesis in the ischemic penumbra is a well-established method of ischemic stroke treatment. Ginkgolide B (GB) has long been recognized for its neuroprotective properties following stroke. As previously reported, it appears that stroke-induced neurogenesis and angiogenesis interact or are dependent on one another. Although the pharmacodynamic effect of GB on cerebral blood flow (CBF) following ischemic stroke has been reported, the molecular mechanism underlying this effect remains unknown. As such, this study sought to elucidate the pharmacodynamic effects and underlying mechanisms of GB on post-stroke angiogenesis. To begin, GB significantly increased the proliferation, migration, and tube formation capacity of mouse cerebral hemangioendothelioma cells (b.End3) and human umbilical vein endothelial cells (HUVEC). Additionally, GB significantly improved angiogenesis after oxygen-glucose deprivation/reperfusion (OGD/R) in endothelial cells. The dynamics of CBF, brain microvascular neovascularization and reconstruction, and brain endothelial tissue integrity were examined in middle cerebral artery occlusion (MCAO) mice following GB administration. Through label-free target detection techniques, we discovered for the first time that GB can specifically target Creatine Kinase B (CKB) and inhibit its enzymatic activity. Additionally, we demonstrated through network pharmacology and a series of molecular biology experiments that GB inhibited CKB and then promoted angiogenesis via the CCT/TRiC-SK1 axis. These findings shed new light on novel therapeutic strategies for neurological recovery and endothelial repair following ischemic stroke using GB therapy.

Neovascularization and tissue regeneration by endothelial progenitor cells in ischemic stroke. Neurol Sci 2021; 42:3585-3593.

Abstract
Endothelial progenitor cells (EPCs) are immature endothelial cells (ECs) capable of proliferating and differentiating into mature ECs. These progenitor cells migrate from bone marrow (BM) after vascular injury to ischemic areas, where they participate in the repair of injured endothelium and new blood vessel formation. EPCs also secrete a series of protective cytokines and growth factors that support cell survival and tissue regeneration. Thus, EPCs provide novel and promising potential therapies to treat vascular disease, including ischemic stroke. However, EPCs are tightly regulated during the process of vascular repair and regeneration by numerous endogenous cytokines that are associated closely with the therapeutic efficacy of the progenitor cells. The regenerative capacity of EPCs also is affected by a range of exogenous factors and drugs as well as vascular risk factors. Understanding the functional properties of EPCs and the factors related to their regenerative capacity will facilitate better use of these progenitor cells in treating vascular disease. Here, we review the current knowledge of EPCs in cerebral neovascularization and tissue regeneration after cerebral ischemia and the factors associated with their regenerative function to better understand the underlying mechanisms and provide more effective strategies for the use of EPCs in treating ischemic stroke.

Non-Mitogenic Fibroblast Growth Factor 1 Enhanced Angiogenesis Following Ischemic Stroke by Regulating the Sphingosine-1-Phosphate 1 Pathway. Front Pharmacol 2020; 11:59. [PMID: 32194396 PMCID: PMC7063943 DOI: 10.3389/fphar.2020.00059] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/13/2019] [Accepted: 01/22/2020] [Indexed: 12/11/2022] Open
Abstract
Ischemic strokes account for about 80% of all strokes and are associated with a high risk of mortality. Angiogenesis of brain microvascular endothelial cells may contribute to functional restoration following ischemia. Fibroblast growth factor 1 (FGF1), a member of FGF superfamily, involved in embryonic development, angiogenesis, wound healing, and neuron survival. However, the mitogenic activity of FGF1 is known to contribute to several human pathologies, thereby questioning the safety of its clinical applications. Here, we explored the effects and mechanism of action of non-mitogenic FGF1 (nmFGF1) on angiogenesis in mice after ischemia stroke and an oxygen-glucose deprivation (OGD)-induced human brain microvascular endothelial cells (HBMECs) injury model. We found that intranasal administration nmFGF1 significantly promoted angiogenesis in mice after stroke, and significantly increased the formation of matrigel tube and promoted scratch migration in a dose-dependent manner in OGD-induced HBMECs in vitro. However, the co-administration of an FGF receptor 1 (FGFR1)-specific inhibitor PD173074 significantly reversed the effects of nmFGF1 in vitro, suggesting that nmFGF1 functions via FGFR1 activation. Moreover, nmFGF1 activated sphingosine-1-phosphate receptor 1 (S1PR1, S1P1) in mice after stroke in vivo. S1P1 protein antagonist VPC23019 and agonist FTY720 were used to confirm that nmFGF1 promotes angiogenesis in vitro partially through the S1P1 pathway. OGD induced downregulation of S1P1 expression. The S1P1 antagonist VPC23019 blocked the stimulatory effects of nmFGF1, whereas the S1P1 agonist FTY720 exerted effects comparable with those of nmFGF1. Furthermore, PD173074 reversed the effect of nmFGF1 on upregulating S1P1 signaling. In conclusion, nmFGF1 enhanced angiogenesis in mice following stroke and OGD-induced HBMECs through S1P1 pathway regulation mediated via FGFR1 activation. This new discovery suggests the potential therapeutic role of nmFGF1 for the treatment of ischemic strokes.
