Abstract

The extracellular matrix (i.e. mesogloea) of Cnidaria presents unique features due to the absence of acidic mucopolysaccharides (Katzman and Jeanloz, 1970; Bocquet et al., 1972) and of morphologically well-defined native collagen fibers. In Actinia equina (Anthozoa, Hexacorallia), the cnidarian collagen molecule was identified as consisting of 3 identical α chains (Nordwig and Hayduk, 1969; Nordwig et al., 1973). This structure, based on a single gene origin, was considered as the possible ancestral form of the collagen molecule. However, more recently Kimura et al. (1983) found more than one kind of a chain in the collagen component of a jellyfish (Scyphomedusae), although he did not characterize them as belonging to specific molecular species of collagen. This paper reports a partial characterization of the mesogloeal collagen of an octocorallian anthozoa: the sea-pen Veretillum cynomorium, and presents new evidence for heterochain composition of the cnidarian collagen.
