Protection of MSCs against hypoxia and serum deprivation-induced apoptosis by preconditioning with rhHsp90α
Rat MSC viability was evaluated by MTT assay. Cell viability was calculated as the percentage of viable cell number of each sample divided by that of the normoxia and serum-contained control. Cell viability of MSCs preconditioned with rhHsp90α at the dosage of 0.1–10 μmol/L was significantly increased compared to that of control (* P<0.05)
