Figure 1From: Induction of superficial zone protein (SZP)/lubricin/PRG 4 in muscle-derived mesenchymal stem/progenitor cells by transforming growth factor-β1 and bone morphogenetic protein-7Phenotype of the cultured rat muscle-derived mesenchymal stem/progenitor cells (MDMSCs). The MDMSCs were STRO-1 and CD166 positives, and negatives for Alkaline Phosphatase (ALP), CD29, CD34, and CD45. The blue line represents the corresponding control isotype.Back to article page
