Fig. 7. Developmental profile of F3/contactin expression in the cerebellum of wild-type (a,c,e,g,i,k,m,o,q,s,u,w) and TAG/F3 (b,d,f,h,j,l,n,p,r,t,v,y) mice shown at postnatal days 0 (a,b; k-n), 3 (c,d; o-r), 8 (e,f; s,t), 11 (g,h; u,v) and 16 (i,j; w,y). (A) Low and (B) high power images. In B, parts k, l, o, p correspond to lobules II and III; parts m, n, q, r correspond to lobules VI and VII. Different levels of TAX-1 promoter activity were observed in these lobules (Fig. 2B). Sections were immunostained with F3/contactin antibodies and counterstained with Hematoxylin (blue). Scale bars: (a-j) 200 µm; (k-v) 40 µm; (w-y) 100 µm.
