Clonal growth and self-renewal of human myeloid leukemia cell lines (BRM and DD) in serum-free semi-solid culture.
Primary and secondary colony formation of two new human myeloid leukemia cell lines (BRM and DD) were studied in serum-free semisolid cultures. The results indicate that bovine serum albumin and transferrin were essential for clonal growth in chemically defined medium. Insulin contributed only moderately beneficial effects. Initial cell density was also a major modulator of plating efficiency. Positive cooperation between the leukemia cells was shown by using autologous conditioned media. This is the first serum-free culture method that allows self-renewal of human myeloid leukemia cell lines in terms of secondary colony formation in methylcellulose cultures.
