  Fig. 1. krt62.L and fgf8 expression in froglet blastema. (A–C) Blastema in the early bud stage. (D–F) Blastema in the mid bud stage. (G–I) Blastema in the late bud stage. (J–L) Early spike stage. (M–O) Spike 2 months after amputation. (A, D, G, J, M) Alcian blue, eosin and Alizarin red staining. (B, E, H, K, N) fgf8 expression was visualized by in situ hybridization. (C, F, I, L, O) krt62.L expression was visualized by in situ hybridization. Scale bar in A and B1 = 1000 µm. Scale bar in B2 = 100 µm. Scale bar in E2 = 200 µm. Scale bar in H1 = 400 µm. A, D, G, J and M are the same magnification. B1, C1, E1, F1 and L1 are the same magnification. B2, C2, H2, I2, L2 and O2 are the same magnification. E2, F2 and N are the same magnification. H1, I1, K and O1 are the same magnification.

  Fig. 4. Denervation effect on krt62.L expression. (A, C, E, G) Histology. (B, D, F, H) krt62.L expression. (A, B, E, F) Sham operated limbs (control). (C, D, G, H) Denervation procedure was performed 11 days after limb amputation. (C, D) The blastema was grown for 3 days after denervation. krt62.L expression domain expanded from the basal to the surface layer. (G, H) The blastema was grown for 7 days after denervation. krt62.L expression had almost vanished from the blastema epithelium. Scale bar in A= 500 µm. Scale bar in B= 300 µm. Scale bar in B′= 100 µm.
