Abstract

Among the invertebrates, the cephalopods seem to have one of the most “evolved” collagens, as collagen molecules composed of two different chains (type I-like collagen) were isolated from skin (Kimura and Matsuura, 1974; Kimura et al., 1981) and intermuscular septa (Takema and Kimura, 1982). However, it is not so far known if cephalopod connective tissues possess the heterogeneity of collagen molecular types which is typical of vertebrates. To contribute to the characterization of collagenic compounds in different tissues and organs, we have studied, with morphological and biochemical meth-thods, the neural sheath of the stellate ganglion of Sepia officinalis.
