Abstract
Summary. Mouse embryos flushed from the reproductive tract on Day 4 or 5 post coitum degranulated peritoneal mast cells in vitro. The degranulating activity of embryos developed with age of embryos: it was absent with Day-3 embryos, present with Day-4 embryos and was increased with Day-5 embryos. Day-4 embryos cultured for 24 h also exhibited degranulating activity. Such activity was even greater for embryos cultured for 48 h. As the degranulating activity of the incubated embryos increased, it was accompanied by an increase in the degranulating activity of the culture medium.
