Expression of msxb and fgf20a during fin regeneration in adult zebrafish (between 6 and 8 months old). A: In situ hybridization of msxb and fgf20a at 0, 24, 48, 72, and 96 hpa, respectively. Dashed lines indicate the plane of amputation. Scale bar = 1 mm. B, C: Real-time RT-PCR analysis of the expression of msxb and fgf20a at different times during regeneration. The expression levels of msxb and fgf20a at 0 hpa (control) were normalized to 1, respectively. Data represents the means ± SE. n = 4 for each measurement. n.s., not significant; *P < 0.05.
