Size-Optimized Microspace Culture Facilitates Differentiation of Mouse Induced Pluripotent Stem Cells into Osteoid-Rich Bone Constructs

Figure 3

Microspace size influences the osteogenic marker gene expression of OI-iPSC constructs. The expression of osteogenic marker genes in Elp400, Elp500, and Elp900 was determined by real-time RT-PCR. (a and b) The gene expression of osteogenic-related transcriptional factors including (a) Runx2 and (b) Osterix (Osx) was determined at day 10 of osteogenic induction. (c–f) After maintenance for 20 days, the expression of bone ECM-related genes-related genes such as (c) Collagen 1a1 (Col1a1), (d) Bone sialoprotein (Bsp), (e) Osteopontin (Opn), and (f) Osteocalcin (Ocn) was evaluated. 18s rRNA expression was used as an internal control. Different letters indicate significant differences between groups (, ANOVA with Tukey’s multiple comparison test). The data represent the ().
