## Abstract Little information is available concerning enzyme activity in primordial germ cells (PGCs) of the early chick embryo. The present study is designed to examine the disposition of alkaline and acid phosphatase activity in the PGCs during their migration into the developing gonads of the e
It is known that chick primordial germ cells (PGCs) in early embryonic development migrate via the blood vascular system to colonize the gonadal anlagen. Classically, two factors have been involved in the extravasation of PGCs from the blood stream: chemotactic and mechanical factors. An accurate kn
Experiments were conducted to elucidate the factor that influences the concentration of circulating primordial germ cells (cPGCs) in two-day old chick embryos. The concentration of cPGCs was observed to be highest at stage 14 (66.9 Β± 23.2 Β΅l) and decreased thereafter. However, considerable egg to eg
