Gene expression analysis for GAPDH, CD29, CD34, CD44, CD90 and MHC-II, of BM-MSCs at passage 3. Gel electrophoresis of PCR products showed the expression of GAPDH (183 bp), CD29 (234 bp), CD44 (193 bp) and CD90 (155 bp). No expression of CD34 and MHC-II was detected. RT had mRNA instead of cDNA template in PCR to exclude DNA contamination. RT: RNA template; NTC: non-template (negative) control.
