Fig. 4From: Synthesis of aligned porous polyethylene glycol/silk fibroin/hydroxyapatite scaffolds for osteoinduction in bone tissue engineeringA ALP staining of rat BMSCs cultured on scaffolds without osteogenic induced media for 7 and 14 days (scale bar = 200 μm). B Semi-quantitative ALP staining data were analyzed by Image J software. C Osteogenesis-related mRNA expression (bone sialoprotein, BSP; osteocalcin, OCN; osteoprotegerin, OPG; runt-related transcription factor 2, RUNX2) of BMSCs after 7, 14, and 21 days of culture on different scaffoldsBack to article page
