Phenotype of ovarian mast cells in neonatal MRL/MpJ mice.

<p>(A) AB/SO sections of neonatal MRL/MpJ mice. (B) TEM examination of neonatal ovarian MCs in MRL/MpJ mice. (C) Expression levels of MMC marker <i>Mcpt2</i>, CTMC marker <i>Tpsb2</i>, and <i>Mcpt2</i> normalized by <i>Tpsb2</i>. Data represent mean ± SEM (n = 4–5 per group).* <i>P</i> <0.05 vs. postnatal day 0 of the same organ. * <i>P</i><0.05 vs. C57BL/6N ovary of the same age. ## <i>P</i><0.01 vs. MRL/MpJ skin of the same age. (D) Immunohistochemistry for BrdU and ssDNA of MRL/MpJ mice ovaries. Ov: ovary. Arrows indicate the caudomedial region of the ovary where mast cells are densely concentrated. In all panels, bottom side represents the medial region.
