TAZ is upregulated during osteogenesis while it is downregulated during adipogenesis in human ADSCs. a Osteogenic differentiation of ADSCs was induced in vitro and monitored by Alizarin Red and von Kossa staining at the indicated time points (days 7, 14, 21, and 28 after induction). Scale bar = 50 μm. b,c Transcriptional coactivator with PDZ-binding motif (TAZ) protein was significantly increased during the osteogenic differentiation process of ADSCs, concomitant with markedly upregulated expression of the osteogenic markers runt-related transcription factor 2 (Runx2), osteopontin (OPN), and osteocalcin (OCN). Representative images of Western blots from three independent experiments are shown. d The mRNA levels of TAZ and the osteogenic markers were significantly increased during ADSC osteogenic differentiation in vitro as measured by quantitative RT-PCR. e Adipogenic differentiation of ADSCs was induced in vitro and determined by Oil Red O staining at the indicated time points (days 7, 14, and 21 after induction). Scale bar = 50 μm. f TAZ protein was significantly downregulated during the adipogenic differentiation process of ADSCs. Representative images of Western blots from three independent experiments are shown. g The mRNA levels of TAZ decreased while the adipogenic marker increased during ADSC adipogenic differentiation in vitro as measured by quantitative RT-PCR. Data shown here are mean ± SD from three independent experiments; #P ˃ 0.05, *P < 0.05, **P < 0.01, by ANOVA.
