Hsp70 expression is modulated in MSCs under stress conditions. FACS data show time-dependent upregulation of (a) surface (s) Hsp70 and (b) cytoplasmatic (cy) Hsp70 by stress factors. Means with SEM of three experiments are shown. ^* P <0.1, ^** P <0.05, ^*** P <0.01, Student’s t test. c Western blots of Hsp70 in normoxic and stressed MSCs at day 42. d WB shows Hsp70 upregulation in primary stromal cells (day 42). e RT-PCR of inducible (hsp70) and constitutive (hsc70) forms of Hsp70, gapdh (loading control)
