Popis: Large lymphocytic cells of human tonsils concentrating in the lighter fractions of a BSA gradient contained both precursors of E rosette-forming cells and lymphocytes carrying μ and γ determinants. These two subpopulations of cells could be separated by retaining the Ig-carrying cells on an anti-Fab column. Cells which did not bind to the column matured within 3–5 days into E rosette-forming cells. The Ig-carrying cells were eluted by medium supplemented with immunoglobulins and continued to secrete γ determinants in vitro . Both types of cells were also distinguished by different profiles of spontaneous [ 3 H]thymidine incorporation, the persisting capacity for division of the E-rosette-maturing cells suggesting that they represent an earlier stage of lymphocyte maturation (precursor T cells).
