Effects of donor age on the quantity of CD34+ cells and total nucleated cells (TNC) in the aspirated marrow. The relationship between the age of the donor and the quantity of TNCs (Panel A, open squares), percentage of leukocytes expressing CD34 (Panel A, filled circles) and the total number of CD34+ cells in the marrow aspirate (Panel B) are shown. R stands for correlation coefficient and P stands for P value both of which were calculated using a regression model.
