The follicle cells which surround the oocytes of starfish are known to both release the hormone 1-methyladenine and to respond to it by an active movement which forms a component of the spawning response to the hormone. In Patiria miniata these flagellated cells are located peripheral to the oocyte and have long cytoplasmic processes which penetrate the vitelline layer to the egg surface to form an adhering zonule-like junction. Within the follicle cell cytoplasm are located elongate filamentous bands which appear to represent a component of the contractile mechanism that mediates follicle cell response to 1-methyladenine. These bands do not resemble the filaments of vertebrate smooth muscle cells (quantity, distribution and size of filaments; lack of dense bodies in the filament mass), nor the contractile units of the superficial epithelium of lower vertebrate follicles.
已知围绕海星卵母细胞的卵泡细胞既能释放1 - 甲基腺嘌呤激素，又能通过一种活跃运动对其作出反应，这种运动是对该激素的产卵反应的一个组成部分。在微小扁樱海星中，这些有鞭毛的细胞位于卵母细胞周围，具有长长的细胞质突起，这些突起穿过卵黄膜到达卵表面，形成类似黏着小带的连接。在卵泡细胞的细胞质内有细长的丝状带，这些带似乎代表了介导卵泡细胞对1 - 甲基腺嘌呤反应的收缩机制的一个组成部分。这些带既不像脊椎动物平滑肌细胞的细丝（细丝的数量、分布和大小；细丝团中缺乏致密体），也不像低等脊椎动物卵泡表面上皮的收缩单位。
