To date, the small size and slow growth of eosinophil colonies in vitro has hampered study of cloned eosinophils. We found enhanced eosinophol colony size and numbers in methylcellulose cultures of bone marrow cells utilizing defined supplemented bovine calf serum (DSBCS) in combination with EL4 conditioned medium (EL4-CM). At days 9, 16 and 23 significantly more eosinophil colonies and more cells/colony were present in cultures incubated with DSBCS/EL4-CM than in cultures incubated with fetal calf serum/EL4-CM. The ability to generate large numbers of eosinophils in vitro should facilitate study of cloned eosinophils.
