Shorter post-LPS hematopoietic recovery in TgR mice. Shown are RBC (× 10⁹) (A), WBC (× 10⁶) (B), and platelet (Plts × 10⁶) (C) counts per mL of FVB/N (dashed line) and TgR (solid line) mice (n = 25) in peripheral blood. (D) Results of morphologic examination of peripheral blood smears from TgR and FVB/N mice, at different time points after LPS injection, as indicated. Asterisks denote significant differences, and results are presented as mean ± SD of WBCs × 10⁶ per mL of blood (P < .02, n = 10). (+) indicates the time point after LPS treatment where quantitation was performed.
