In the present study, we demonstrate that quail junctional endoblast fragments have powerful embryo-inducing potencies when placed on the deep side of the upper layer (UL) of the anti-sickle region of unincubated chicken blastoderms. Moreover, in most cases the inducing potencies of the autochthonous Rauber's sickle-endophyll complex were inhibited at distance. Also, junctional endoblast still in situ in an early streak embryo strongly inhibits the inducing capacities of a Rauber's sickle - endophyll complex apposed on the deep side of the upper layer of the cranial part of the area pellucida. So junctional endoblast, besides embryo inducing potencies also seems to dominate and to inhibit at distance the gastrulation potencies of an ectopically placed or autochthonous Rauber's sickle - endophyll complex. |
