The possibility of using DNA image cytometry in hematological material was evaluated in 27 Feulgen stained normal bone marrow smears. The 95% normal limits of DNA index (DI) determined separately for each cell population in bone marrow were 0.89-1.15, 0.93-1.09 and 0.92-1.12 for blasts, granulocytes and lymphocytes, respectively. The mean DI for blasts, granulocytes and lymphocytes was 1.02, 1.01 and 1.02, respectively. In the blasts population the mean percentage of cells in S+G2/M phase was 38.1% (S.D. 12.9%, range 14.3-65.6%), whereas the corresponding values for granulocytes and lymphocytes were below 1%. Calculation of DI and G0 G1 C.V. obtained in bone marrow smears subjected to Feulgen hydrolysis (5 N HC1, 22 °C) for different periods of time revealed the presence of a plateau of results between 60 and 120 min for all of the cell types. The intraobserver and interobserver reproducibility was confirmed by duplicate measurements of each subpopulation (P > 0.05). A comparison of DI and GO/G1 C.V. using smears from the same donors stained with the Feulgen method either straight away or after destaining from May-Grunwald-Giemsa confirmed that destained smears can be used, provided applying appropriately prepared reference cells. We conclude that image cytometry can be used reliably to analyze DNA content in hematological material.
