Fig. 1From: Establishing a deeper understanding of the osteogenic differentiation of monolayer cultured human pluripotent stem cells using novel and detailed analysesAnalyses of cell viability and telomerase activity for hPSCs during 35 days of osteogenic differentiation. a A schematic diagram of the experimental protocol. b, c After osteogenic induction for various days (0, 3, 7, 14, 21, 28 and 35), the cell viability of hESCs (b) and hiPSCs (c) was detected using the CCK8 reagent. d, e The telomerase activities of hESCs (d) and hiPSCs (e) were measured by a quantitative method based on a quartz crystal microbalance (QCM). *Represents p < 0.05 (n = 3)Back to article page
