Establishment of a cell line derived from top-minnow (Gambusia patruelis).
A cell line, derived from top-minnow (Gambusia patruelis), has been transferred for 114 times in Leibovitz L-15 medium plus 10% FCS (GM-L-15) at a temperature of 31 degrees C and designated as TM. The results of a chromosome analysis of 100 cells at the metaphase stage, show a bimodal distribution of the chromosome number ranged from 21 to 68 with a modal number of 38. At a low seeding density, the plating efficiency of TM cells was 11-12.4%. TM cells are susceptible to EVE, EVA, EVEX, IPNV and LV-1 at 18 degrees C. The result of a sterility test showed that the TM cell line was free of bacterial, fungal and mycoplasmic contamination. The presence of numerous microvilli on the surface of TM cells in the micrographs of normal TM cell. The microvilli are replaced by blebs at the late stage of cytokinesis of the cells.
