Abstract: | Summary Pairs of eye-antennal discs, attached to the cephalic ganglia, were cultured in vitro with a concentration of -ecdysone optimal for imaginal differentiation. The eye-antennal discs fused to form a vesicle inside which the antennae were partially everted, and on the inner surface of which imaginal structures differentiated. The epithelium of the discs was continuous, and an integrated pattern of bristles and hairs differentiated in vitro. In particular, the median ocellus, a unified structure derived partially from each disc, differentiated normally. |
