Pulses of ammonia and methylamine induce down-regulation of nematocyte and nerve cell populations in Hydrozoa (Hydra; Hydractinia)
Hydrozoa replace used-up nematocytes (cnidocytes) by proliferation and differentiation from interstitial stem cells (i cells). Repeated pulsed exposure ofHydra to elevated levels of unprotonated ammonia leads to successive loss of the various types of nematocytes: first of the stenoteles, then of th...
