Abstract: | Summary Physiological peak doses of 20-hydroxyecdysone were added to organ cultures of young pupal accessory glands of maleTenebrio molitor. During subsequent culture in vitro or in vivo, the glands accumulated adult-specific antigens. Control organ cultures showed no such antigen accumulation. In this system, ecdysteroid controls not only cell cycles but also differentiation.21 October 1986This research was supported in part by a National Institutes of Health Research Service Award F32 AM7515 (KAG) and NIH grants GM26140 and AI15662 (GMH). We thank Toshinobu Yaginuma for help in developing the transplantation technique. |
