Different pathway of T-helper cell recovery in thymectomized and thymus-bearing hosts. Absolute cell numbers (expressed as cells per microliter) of total CD4+ cells (▪), of CD45RA+ cells (♦), and of CD45RO+ cells (○) were calculated by multiplying the fraction of cells staining positive by the absolute lymphocyte count that was derived from the differential count of white blood cells. The graphs show the absolute cell count of the individual T-cell subsets in 3-month intervals after allogeneic BMT.
