Percentage of S-phase cells in bone marrow aspirates, biopsy specimens and bone marrow aspirates corrected for blood dilution from patients with acute leukemia.
For 14 patients with acute leukemia flow cytometry was used to determine the percentage of cells in S-phase flushed out of a bone marrow biopsy compared with the percentage in a bone marrow aspirate; there was a statistically significant difference (p less than 0.01) between the two. The percentage dilution of the bone marrow aspirate by peripheral blood was then calculated, according to Holdrinet et al. [1], in order to correct the percentage S-phase cells in the aspirate. The data presented show that when the percentage S-phase cells in the aspirate is corrected for blood dilution, it closely approaches the percentage S-phase cells in the biopsy (p greater than 0.10).
