Acute lymphoblastic leukaemia cells in the diffusion chamber: change of surface phenotype during the culture period

Summary. Peripheral blast cells from patients with acute lymphoblastic leukaemia were cultured in the diffusion chamber system. On different harvesting days the cALL antigen, surface immunoglobulin and T‐cell antigen were investigated by direct immunofluorescence. Each cell type investigated showed a different response throughout culture, the commonest change observed being development into the B‐cell axis.
