Summary of bone marrow colony formation in semisolid agar from patients with acquired PAP (n = 4) and concurrent normal controls (n = 5). Duplicate cultures of 5 × 104 bone marrow mononuclear cells were stimulated with supramaximal concentrations of the individual growth factors shown, and the mean of the resulting colonies expressed as a percentage of the total CFU-GM from that individual formed in response to combined growth factor stimulation (see Materials and Methods). Data are expressed as the mean ± SD.
