摘要：

In mice, homozygous Lgr4 inactivation results in hypoplastic kidneys. To understand better the role of LGR4 in kidney development, we performed an analysis of kidneys in Lgr4(-/-) embryos. We stained Lgr4(-/-) kidneys with anti-WT1 and anti-Cleaved Caspase3 antibodies at E16.5, and observed that the structures of the cap mesenchyme were disrupted and that apoptosis increased. In addition, the expression of PAX2, an anti-apoptotic factor in kidney development, was also significantly decreased at E16.5. We found that the LGR4 defect caused an increase in apoptosis in the peripheral mesenchyme during kidney development.
