Fig. 5. ELPC-induced mechanism in chondrogenic differentiation.
a The mRNA expression of p53 in the ELPC-treated ASCs. ***p < 0.001 compared to the control. n = 3. b The protein expression of p53 in the ELPC-treated ASCs. *p < 0.01, **p < 0.05 compared to the control. n = 3. c The ASCs treated with ELPC for 24 h were separated into the nuclear and cytosolic fractions. p53 was quantified and normalized to Lamin B2 and α-tubulin in the nucleus and cytosol, respectively. Cont Control, D DMSO-treated ASCs. *p < 0.01 **p < 0.05 ***p < 0.001 compared to the control. n = 3. d The translocation of p53 was confirmed by immunofluorescence staining. p53 was detected by FITC green fluorescence. The nucleus was stained with DAPI (blue). Scale bar: 30 μm. e, f The protein expression levels of Sox9 and Type II collagen in the ELPC-treated ASCs were investigated 24 h after transfection with 50 nM p53 siRNA. ***p < 0.001 compared to the control, #p < 0.05 compared to the ELPC-treated ASCs. $p < 0.001 compared to the reagent- and ELPC-treated ASCs. n = 3.
