海星（Asterina pectinifera）的神经提取物中含有的性腺刺激物质（GSS）作用于卵巢，产生一种负责卵母细胞成熟的活性物质，即减数分裂诱导物质（MIS）。在Sephadex上通过凝胶过滤成功地从GSS中分离出MIS。MIS部分也具有诱导产卵的活性。海星睾丸在GSS作用下也产生MIS。在6种海星中发现了MIS的产生。虽然GSS具有一定的物种特异性，但在MIS中没有观察到这种特异性。
The gonad‐stimulating substance (GSS) contained in nerve extract of the starfish, Asterina pectinifera, acts on the ovary to produce an active substance responsible for oocyte maturation, meiosis‐inducing substance (MIS). MIS was successfully separated from GSS by gel‐filtration on Sephadex. The MIS fraction had also spawning‐inducing activity. Starfish testis also produced MIS under the influence of GSS. MIS production was shown in six starfish species. Although some species specificity characterizes GSS, this was not observed in MIS.
