Gene expression analysis of adipose tissue-derived mesenchymal stem cells (aMSCs) by means of semi-quantitative RT-PCR. Legend: − not expressed; + target gene expression <25% of β actin expression; ++ target gene expression 25–50% of β actin expression; +++ target gene expression >50% β actin expression. Results are the average of analysis of three different aMSC populations.
