Abstract
Neurosecretory granules of Hydra littoralis were isolated by differential centrifugation. Excised midsegments of hydra that were exposed to the fraction containing neurosecretory granules developed additional heads at any site, as they regenerated. Hence neurosecretory granules may contain a factot that regulates or stimulates growth in normal and regenerating hydra.This publication has 5 references indexed in Scilit:
