Cytology and the number of urinary cells in BXSB/MpJ and C57BL/B6.

<p>(a and b) Comparison of urinary smears from BXSB/MpJ (a) and C57BL/6 (b) mice. Bar = 50 µm. Urinary cell numbers in BXSB/MpJ mice are higher than those in C57BL/6 mice. (c) Numbers of urinary cells in BXSB/MpJ and C57BL/6 mice. *, significantly different from C57BL/6 mice (Mann–Whitney <i>U</i> test, <i>P</i><0.05); <i>n</i> = 11. (d–i) Morphology of urinary cells in BXSB/MpJ mice stained with HE (d–f) and SM (g–i). Small round cells (d and g), homogeneous and amorphous cell components (e and h), and columnar cells (f and i) are observed. Bar = 50 µm.
