Glomerular Cell Number and Labeling Index

Age: 18 weeks (8 weeks after NX)		ROP +/+	C57 +/+	ROP Os/+	C57 Os/+
Cells/50 glomeruli	Sham	2429 ± 181	2599 ± 319	3276 ± 411†	3139 ± 400
	NX	2396 ± 223	2379 ± 123	3132 ± 146†	3403 ± 101†
Labeled cells (%)	Sham	0.26 ± 0.06	0.29 ± 0.03	0.78 ± 0.25†	0.76 ± 0.28†
	NX	0.64 ± 0.1*	0.54 ± 0.1*	0.84 ± 0.18	0.80 ± 0.05

Glomerular cell number and labeling index were measured as described. Data are means of six experimental mice per group.

*P < 0.001; ROP +/+ NX and C57 +/+ NX versus sham-operated littermates.

^†P < 0.001; ROP Os/+ NX versus ROP +/+ NX, ROP Os/+ sham versus ROP +/+ sham, C57 Os/+ NX versus C57 +/+ NX, C57 Os/+ sham versus C57 +/+ sham.
