In the mature planula two major kinds of derivatives differentiate from interstitial cells: a single type of bipolar ganglion cell and four types of nematoblasts. Of the latter only three types (desmonemes, stenoteles, and microbasic heterotrichous b-mastigophores with inclusions) complete differentiation in the planula; only a few nematocytes with bullet-shaped capsules (microbasic heterotrichous b-mastigophores with inclusions) were ever found in the planula.
In the planula the interstitial cells, nematoblasts, and neuroblasts emigrate from the endoderm to the ectoderm.
