Hematopoietic support by GAS6-transfected 3T3 Cells. (a) CFU-c in cultures supported by GAS6-transfected 3T3. Results from three representative experiments are shown. The results presented are for total CFU-c per 2.0 ml culture and are uncorrected for the loss of nonadherent CFU-c at each feeding. The values shown are mean ± SD (n = 4–6). (b) Nonadherent cells per culture. The results from a single experiment (Exp. 3 above) are shown. The values shown are mean ± SD (n = 6) and are uncorrected for the consequences of demi-depletion at each weekly feeding.
