Growth of rainbow trout hemopoietic cells in methylcellulose and methods of monitoring their proliferative response in this matrix

  • Published:

Abstract

A technique for the clonal culture of rainbow trout leukocytes in a methylcellulose matrix can be used to identify growth factors and other substances affecting cell proliferation and development in fish. Methylcellulose supports colony formation by rainbow trout leukocytes isolated from the major hemopoietic organ, the pronephros. The addition of rainbow trout serum dramatically increased the number of colonies formed, scored by counting colonies. As an alternative measure of cell proliferation, 3H-thymidine incorporation by cells can be easily measured in methylcellulose cultures. This method requires only small amounts of test substances, is rapid, and is superior for assessing the growth-stimulating ability of some substances, such as bacterial lipopolysaccharide, which stimulated growth but not the formation of discreet colonies by rainbow trout cells.
