The differentiated cell types of the mature ureter arise from the distal ureteric
bud epithelium and its surrounding mesenchyme. Uncommitted epithelial cells first
become intermediate cells from which both basal and superficial cells develop.
Mesenchymal progenitors give rise to separated layers of adventitial fibrocytes,
smooth muscle cells and lamina propria fibrocytes. How progenitor expansion and
differentiation are balanced is poorly understood. Here, we addressed the role of
retinoic acid (RA) signaling in these programs. Using expression analysis of
components and target genes, we show that pathway activity is restricted to the
mesenchymal and epithelial progenitor pools. Inhibition of RA signaling in ureter
explant cultures resulted in tissue hypoplasia with a relative expansion of
smooth muscle cells at the expense of lamina propria fibroblasts in the
mesenchyme, and of superficial cells at the expense of intermediate cells in the
ureteric epithelium. Administration of RA led to a slight reduction of smooth
muscle cells, and almost completely prevented differentiation of intermediate
cells into basal and superficial cells. We identified cellular programs and
transcriptional targets of RA signaling that may account for this activity. We
conclude that RA signaling is required and sufficient to maintain mesenchymal and
epithelial progenitors in early ureter development.
