Isolated, mononucleated, cross-striated muscle of a medusa can be activated by collagenase treatment to transdifferentiate completely to various new cell types and to regenerate autonomously the sexual (without gametes) and feeding organ of the animal. Under these circumstances all isolated muscle fragments produce smooth muscle cells and a glandular cell type (y-cells). When culture conditions are appropriate, endoderm is also formed, followed by regeneration of a complex organ of seven or eight new non-muscle cell types, including nematocytes, digestive, secretory, gland, interstitial, and presumably nerve cells.
水母分离出的单核横纹肌可通过胶原酶处理被激活,从而完全转分化为各种新的细胞类型,并自主再生该动物的有性生殖器官(无配子)和摄食器官。在这些情况下,所有分离出的肌肉片段都会产生平滑肌细胞和一种腺细胞类型(γ细胞)。当培养条件适宜时,还会形成内胚层,随后再生出一个由七八种新的非肌肉细胞类型组成的复杂器官,包括刺细胞、消化细胞、分泌细胞、腺细胞、间质细胞以及推测的神经细胞。
