Fig. 1. Transient expression of G4/5 in pre-lam5 in the PBM of epidermal wounds. Excisional wounds in mouse skin were healing for 7 days (a and c), or about 14 days (b and d). Cryostat sections of the wounds were probed with rabbit Mab R5808-f1 against mouse G5 in laminin {alpha}3 (a and b), or rat Mab against mouse lam5 (P3C8, c and d). Migrating leading cells in the partially healed wound expressed G4/5 (a) and lam5 (c), whereas closed wounds downregulated G4/5 (b) but maintained lam5 (d) (leading cells in outgrowth indicated with arrow; provisional BM indicated by arrowheads).
