Regeneration of the caudal fin in adult zebrafish at different ages. A: Caudal fin growth at 48 hpa. 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 in regenerating fins at 48 hpa in zebrafish at different ages. The expression levels of msxb and fgf20a in 4-month-old animals were normalized to 1, respectively. Data represents the means ± SE. n = 4 for each measurement. n.s., not significant.
