We studied myeloid progenitor cells (CFUc) from peripheral blood mononuclear leukocytes (MNL) of normals and patients with severe aplastic anaemia (AA). Baseline CFUc averaged 4.4 +/- 1.5 (range 0--17)/10(6) MNL in fifteen normals and 0 +/- 1/10(6) MNL in six patients with severe AA (P less than 0.05). To assess CFUc proliferative capacity, 10(7) MNL were put into liquid culture in Marbrook chambers with colony-stimulating activity and sub-cultured in agar at intervals up to 10 days. CFUc from normal MNL increased from 44 +/- 15/chamber at Day 0 to 156 +/- 33/chamber at peak value (P less than 0.02). In contrast, CFUc from AA MNL remained undetectable throughout the period of liquid culture (AA peak v. normal peak; P less than 0.001). These results indicate a marked decrease in circulating CFUc in patients with severe AA, and a profound abnormality in CFUc proliferation in vitro. This abnormality could be due to defective replication of CFUc, a lack of feed-in from more primitive precursors, or both.
