KGF durably improves post-BMT thymopoiesis.

(A) PBS- or KGF-treated congenic BMT recipients after 1400 cGy conditioning analyzed over the 3 months following BMT. Shown are mean absolute thymocyte numbers ± SD. Gray bar, non-BMT control; diagonally hatched bar, donor-derived thymocytes; black bar, host-derived thymocytes. (B) PBS- (vertically hatched bar) or KGF-treated (cross-hatched bar) allogeneic BMT recipients after 900 cGy conditioning analyzed over the 3 months following BMT. Shown are mean absolute thymocyte numbers ± SD.
