Correlations between the levels of TNF-α in LTBMC supernatants and the numbers of myeloid progenitor cells and apoptotic CD34⁺ cells.

Diagrams show linear regression analysis for the correlation between the values of TNF-α in LTBMC supernatants and the number of total CFU-GMs (A), the percentages of CD34⁺/Fas⁺cells (B), and the proportions of CD34⁺/7-AAD⁺cells (C) in the entire group of subjects studied (26 CIN patients and 12 healthy controls). Coefficient of correlation (r) and degree of significance (P) are indicated. Regression lines are shown as solid lines and the 95% confidence limits as dotted lines. CIN patients (●); healthy controls (○).
