Fig. 4From: Comparative evaluation of mesenchymal stromal cells from umbilical cord and amniotic membrane in xeno-free conditionsAMMSCs in PL showed similar chondrogenic differentiation potential with UCMSCs. a The chondrogenic differentiation of AMMSCs and UCMSCs was confirmed by Alcian Blue staining of glycosaminoglycans. Magnification × 100. b Comparative investigation of chondrogenic differentiation capability of UCMSCs and AMMSCs was assessed by quantitative analysis of SOX-9 and collagen II mRNA expression.
