Insight into stem cells, microenvironment and methods for promoting blood circulation and removing stasis / 中国组织工程研究

ABSTRACT

BACKGROUND:There is a certain association between stem cels, microenvironment and methods for promoting blood circulation and removing stasis. OBJECTIVE:To propose a perspective of“kidney properties”of promoting blood circulation and removing stasis by elaborating the correlation and interactions of stem cels and microenvironment with methods for promoting blood circulation and removing stasis. METHODS:A computer-based search of Chinese Journal Ful-text Database, Wanfang and PubMed was performed for articles published form 2009 to 2015 addressing improving stem cel proliferation and differentiation by promoting blood circulation and removing stasis as wel as microenvironments. The keywords were “bone mesenchymal stem cels, transformation, differentiation, blood-activation and stasis-resolved method, microenvironment” in Chinese and English, respectively. Finaly, 32 literatures were reviewed. RESULTS AND CONCLUSION:Stem cels homing to the damaged tissue trigger an“environment-dependent differentiation”,that is, stem cels candifferentiate into myocardial cels, vascular endothelial cels and other injured tissues and cels under local special microenvironments. Microenvironment as an assembly for integrating dynamic, microscopic changes as wel as development of a variety of indices is of great importance for stem cel survival, proliferation and differentiation. Recipes for promoting blood circulation and removing stasis are involvedto regulate multi-steps and multi-targets during stem cel homing. Theoreticaly, this review attempts to investigate correlation among stem cels, microenvironment and methods for promoting blood circulation and removing stasis in association with previous preclinical and clinical findings. Here, we further refine the view of “kidney properties” of promoting blood circulation and removing stasis and clarify that stem cels as the material basis of “kidney properties”of promoting blood circulation and removing stasis is the main executor for promoting blood circulation and removing stasis. This paper is of a certain value for fuly revealing the scientific connotation of the theory of promoting blood circulation and removing stasis.
