[The characteristic of the coelomic fluid and coelomic epithelium cell populations of starfish Asterias rubens L., capable to attach and spread on various substrates].

Cultivation is one of the methods modeling processes occurring in vivo. The success of cultivation, in particular, is defined by a substratum choice. We studied the ability of coelomocytes and coelomic epithelial cells to attach and spread to fibronectin, laminin, polylysine, and glass. Qualitative composition of heterogeneous populations of coelomocytes and epithelial cells was determined after staining the cells with rhodamine-phalloidin and DAPI, and changes in the composition of populations evaluated in response to injury. Seven relative classes of coelomocytes has been identified, three of which has been shown to participate in the formation of clot during primary repair of wounds. There was a change in the proportion of these cells, attached to specific ligands in response to the injury. In coelomic epithelium 8 relative classes of cells has been identified, two of which are likely to be candidates for the role of progenitor cells for coelomocytes--coelomocyte-like and small epithelial cells with high nuclear-cytoplasmic ratio. The enrichment with the small cells in population of attached coelomic epithelium cells has been revealed when seeding on laminin. Continued viability of epithelial cells has been shown when cultured on laminin during 2 months.
