Summary
Two fibroblast-like cell lines were obtained from fins of adults of the medaka,Oryzias latipes, and serially cultured at 27° C. One cell line, which was derived from a fish of the orange-red variety, reached to population doubling level (PDL) 434 on Day 840 by 120 passages. The other, which was derived from a fish of the inbred strain HB32C, reached to PDL 294 on Day 551 by 80 passages. Any symptom of crisis was not detected. The cell lines were named OL-17 and OL-32, respectively. Population doubling time was 29 h for OL-17 cells, and 32 h for OL-32 cells. Density-dependent inhibition of growth was clear in OL-32 cells, but not so obvious in OL-17 cells. Modal chromosome number of OL-17 cells was 50, and that of OL-32 cells was 47 (2N=48). Plating efficiency of OL-17 cells was about 10%, whereas that of OL-32 cells was about 5%. The use of conditioned medium (80% concentration) increased the plating efficiency of OL-32 cells to more than 25%.
