A Procedure for Explanting the 72-Hour Chick Embryo. ∗

Abstract

Summary

We have developed a technique for explanting the 72-hour embryo and the entire area vasculosa onto a solid albumenagar medium. With this technique, we were able to maintain such explanted embryos for periods up to 24 hours and longer. Explanted embryos were used for detailed studies of radiation effects on the microcirculation. Considerable expansion of the area vasculosa was observed in explants maintained for 24 hours.
