Effects of cerium oxide exposure on ATII cell morphology and proliferation. The micrographs of TEM (A) and FESEM (B) of ATII cells, which were isolated for control- or CeO2 (3.5 mg/kg)-exposed rats at 28 days post-exposure. CeO2 induced ATII cytotoxicity was measured as proliferation rate of ATII cells. The effect of the first BALF from control or CeO2-exposed rats on primary ATII cell proliferation was shown in panel C. The BALF was used with no dilution as 100%; or at 75%, 50% or 25% concentration of the CeO2-exposed BALF. *Significantly different from control at p < 0.05.
