Explanting chick embryo duodenal tissue elicits an increase in the activities of alkaline phosphatase and maltase, an effect which is greatly enhanced by the addition of thyroxine. A large part of the elevated enzyme activity is released into the culture medium, from which it can be sedimented by centrifugation at 200 000 X g. The resulting pellet contains(More)
If duodenal tissue from 14-day chick embryos is cultured in chemically defined medium, more than twice as many goblet cells appear within 48 hours as in intact embryos during the same time. The increase in goblet cell number is further accelerated by 10(-9) molar thyroxine but is prevented by 10(-6) molar hydrocortisone. The results suggest that(More)
