A metamorphosis-inducing factor was isolated from medium conditioned by either metamorphosing larvae or 3-day postmetamorphic primary polyps. The factor has a molecular weight ≥ 8 kDa and is heatlabile. It does not induce metamorphosis of isolated posterior fragments and is therefore not identical to the internal signal described by Schwoerer-Böhning et al. (1990). The biological significance of the substance is currently unclear, therefore its inducing activity may be a side effect.
一种变态诱导因子是从变态幼虫或变态后3天的初级息肉所分泌的培养基中分离出来的。该因子分子量≥8 kDa，且对热不稳定。它不会诱导分离出的后部片段发生变态，因此与施沃勒 - 伯宁等人（1990年）所描述的内部信号不同。目前尚不清楚该物质的生物学意义，因此其诱导活性可能是一种副作用。
