[Characteristics of a mastocytoma cell line adapted to in-vitro culture].

A cell line adapted to in vitro culture was obtained starting from ascites type mastocytoma cells which were maintained by successive transplantation in mice. The cells make colonies in liquid culture medium as well as on agar plate. In comparison under microscope and of behaviour in abdominal cavity of mice, no difference was detected between cells of this cell line and those of original one.
