Methods Density gradient centrifugalization combined with adherence method were used to segregate and cultivate rat MSCs. MSCs cultivated to the 3 rd passage were characterized using flow cytometry technique. TGF-β1 with 1, 2 and 5 μg/L were pretreated on MSCs for 8 h, then serum and oxygen deprivation were used to cause analogous ischemia of MSCs in vitro. AnnexinV/PI flow cytometry technique was used to evaluate apoptosis and survival of MSCs.
