BMC from TLR2^−/− mice showed impaired proliferation capacity Colony-forming units Granulocyte/macrophage was quantified in BMC obtained from TLR2^−/− and WT mice with or without exposure to IR (6.5 Gy)

(A) The TLR2^−/− and WT mice were exposed to 6.5 Gy, femurs were harvested 5, 14 and 20 days later and the proliferation of BMC was measured by the BrdU assay. All data are expressed as the mean ± s.d. of three separate experiments. *P < 0.05.
