Fig. 2 PLLn outgrowth is normal in Schwann cell-deficient mutants. (A,B) At 28 hpf, axons and Schwann cells of heterozygous siblings (A) and axons of erbb2^st61 mutants (B) are located within the epidermis (ep) (n=3 in A and n=6 in B), and are associated with pre-neuromast cells (pn). (A′,B′) Higher magnification of the boxed regions in A,B, respectively. Arrowheads indicate the location of the epidermal basement membrane. Scale bars: 5 μm in A,B; 1 μm in A′,B′. Schwann cells are pseudocolored green and axons in red. Abbreviations: ep, epidermis; m, muscle; pn, pre-neuromast cell.
