Abstract:

BACKGROUND: Following ischemic/hypoxic brain injury, neurogenesis and neurofunctional recovery are closely related to vascular formation and plasticity in ischemic region. Vascular endothelial progenitor cells participate in vascular formation and repair in postnatal ischemic tissue, promote the recanalization of blood flow and the supply of nutritive substances such as oxygen, providing microenvironment for neurofunctional recovery.
OBJECTIVE: To evaluate the feasibility, efficacy and safety of use of autologous vascular endothelial progenitor cells in the treatment of ischemic/hypoxic brain injury and investigate a new method for improving the neurological function of patients with ischemic/hypoxic brain injury.
METHODS: A computer-based online retrieval of PubMed, ScienceDirect, Springerlink and CNKI databases was performed for papers describing use of vascular endothelial progenitor cells in the treatment of ischemic/hypoxic brain injury using the key words “EPCs, endothelial progenitor cell, stroke” in English and Chinese. In the same research filed, papers that published recently or in high impact factor journals were selected. A total of 43 papers were suitable for final analysis.
RESULTS AND CONCLUSION: Following ischemic/hypoxic brain injury, neurogenesis and neurofunctional recovery are closely related to vascular formation and plasticity in ischemic region. Vascular endothelial progenitor cells participate in vascular formation and repair in postnatal ischemic tissue, promote the recanalization of blood flow and the supply of nutritive substances such as oxygen, providing microenvironment for neurofunctional recovery. The use of autologous vascular endothelial progenitor cells in the treatment of ischemic/hypoxic brain injury is feasible, safe and effective. Nevertheless, a larger number of biological and animal experiments are needed for providing theoretical evidence for clinical application of autologous vascular endothelial progenitor cells.
