The morphogenesis of the special layer and the interstitial cells of Cajal (ICC) related to the plexus muscularis profundus (PMP) of mouse intestinal muscle coat has been studied in foetuses at term, neonates not yet fed, suckling animals, weaning animals and adult animals. In foetuses at term, the special layer is absent, but presumed myoblasts of this layer are recognized in the tela submucosa facing the developing circular layer. The ICC, too, are not differentiated and presumed ICC-blasts are tentatively identified in submucosal cells related to nerve fibers. These nerve fibers are considered to belong to the developing PMP. In neonates, the special layer, ICC and PMP are recognizable, but are made up of poorly differentiated elements. In suckling animals, these three structures develop but become almost fully differentiated only at the end of the weaning period, whereas the other components of the muscular coat are already developed.
对足月胎儿、未进食的新生儿、哺乳期动物、断奶期动物和成年动物的小鼠肠肌层深层神经丛（PMP）相关的特殊层和Cajal间质细胞（ICC）的形态发生进行了研究。在足月胎儿中，特殊层不存在，但在面向发育中的环形层的黏膜下层中可识别出该层的假定成肌细胞。ICC也未分化，在与神经纤维相关的黏膜下层细胞中初步鉴定出假定的ICC前体细胞。这些神经纤维被认为属于发育中的PMP。在新生儿中，特殊层、ICC和PMP是可识别的，但由分化不良的成分组成。在哺乳期动物中，这三种结构发育，但仅在断奶期末几乎完全分化，而肌层的其他成分已经发育。
