ABSTRACT
Objective To study the effects of muscular trumatic fluid on the biological properties of muscle-derived stem cells (MDSCs) in rats.Methods MDSCs were isolated and purified by the preplate technique,muscle injury was made for the extraction of muscular traumatic fluid.Bradford colorimetric was used to detect the protein content in the muscular traumatic fluid,and the fluid with the highest protein was used to co-culture with MDSCs.Methyl thiazolyl tetrazolium (MTT) assay and wound model of monolayer of cells were used to observe the effects of wound fluids on the proliferation and mobility of MDSCs.The expressions of α-SMA and Vimentin were tested by immunohistochemistry and Western blot technique.Results MTT assay showed that wound fluid with concentration of 10% could most significantly increase the proliferation of MDSCs.The increased expressions of α-SMA and Vimentin were found in MDSCs after cultrue with muscular traumatic fluid in vitro,and the time-dependent relation exists.Conclusions Wound environment can directly participate in the muscle regeneration by inducing the proliferation,mobility of MDSCs;on the other hand,MDSCs can differentiate into fibrotic cells under stimulation of muscular traumatic fluid.
