In this paper, the different ages of the chicken and quail embryonic retina cell aggre-gates are used to examine the aggregation, histogenesis, and the induction of glutamine syn-thetase (GS) elicited by hydrocortisone. The results show that the GS inducibility in theretina cells increases at a slow rate, then rises sharply on the 9th day, and after 9 days,the GS inducibility of aggregates decreases with the increase of embryonic age. The observedvalue of induced GS activity in the chick retina cells coaggregate with quail embryonic retinacells is less than the expected value. Bispecific cell coaggregrates were observed when the9-day chicken embryonic retina cells and the 7(1/2)-day quail embryonic retina cells were com-bined and coaggregated, the chicken and quail cells formed three retinal rosettes. When the9-day chicken embryonic retina cells were commingled with the 13-day quail embryonic retinacells, in the coaggregates, only one retinal rosette was formed.
