Effect of SDA-collagen type I on the expression of alkaline phosphatase (ALP) and osteocalcin (OC) in bone marrow mesenchymal stem cells (BMSCs) after 14-day treatment (in osteogenic induction medium). (a) mRNA expression as assayed via real-time PCR. Data shown are normalized means + SD relative to β-actin mRNA levels (). denotes a significant difference (). (b) Representative Western blots of ALP and OC protein expression (). Results were quantified via densitometry with the maximum grey value set to 1. All blots were run under the same experimental conditions.
