Quantitative PCR measurements of type I collagen (α1 and α2 chain) gene expression levels in MSCA-1⁺ JPCs cultured under DMEM (serum-containing) and MC conditions (serum-free). (a) mRNA levels of type I collagen (α1 chain) and (b) (α2 chain) in relation to the housekeeping gene GAPDH are illustrated in untreated (co) and osteogenically induced (ob, for 10 days) MSCA-1⁺ cells. Statistical significances are indicated by asterisks: .
