This study describes the temporal pattern of posterior positional identity in mouse limb bud cells. To do this wedges of tissue from the posterior edge of mouse limb buds at various stages (limb stages: Wanek et al., 1989b. J. Exp. Zool. 249, 41-49) were grafted to the anterior edge of a host chick embryo wing bud. Grafts of mouse posterior cells are able to induce the formation of supernumerary digits every time when they are taken from buds from stage 3 through stage 6. At stage 7, the… CONTINUE READING
