1. 1. The behaviour of ATPase activity during embrionic development of chick embryo epidermis has been studied in the absence or presence of a single inoculation of EGF at the fifth day from fertilization (0-day). 2. 2. EGF strongly decreases ATPase activity by affecting Na+ /K+ ATPase. This effect occurs only if begun at 0-day. 3. 3. This effect is due to the EGF induced decrease of -SH groups that are active part of Na+/K+ ATPase.
