Some Biological and Biochemical Properties of the Polarizing Factor in Hydra

Nature volume 204, pages 492–493 (1964)Cite this article

Abstract

TRIPP1 proposed a growth pattern for Hydra which was later confirmed by Brien2 and Burnett and Garofalo3. Beneath the hypostome of Hydra a growth region exists where cell proliferations constantly occur. Cell divisions in this area force adjacent cells distally to the tentacle tips and proximally to the basal disk. When cells reach the extremity of the body column they die and are sloughed off. Thus, the animal is capable of continual growth without a change in form.
