a Experimental design. Mice containing Slc1a3-CreERT and Ai9 reporter are injected with tamoxifen to induce expression of modified red fluorescent protein (tdTomato) in cells expressing Slc1a3. b Top row, tdTomato expression (red) 1, 30, and 360 days post induction (DPI) with tamoxifen. Lower rows, tdTomato+ progeny of Slc1a3+ cells express differentiation markers for stem (SLC1A3, orange, arrows), ciliated (FAM183B, orange, arrows), and secretory (OVGP1, orange, arrows) cells. Counterstaining with DAPI (blue). Scale bar represents 50 μm (tdTomato, FAM1A3/tdTomato, OVGP1/tdTomato rows), and 25 μm (SLC1A3/tdTomato row). c Quantification of cells expressing tdTomato in the distal and proximal regions of the uterine tube 1, 30, and 360 DPI. Quantification of cells expressing tdTomato with stem (SLC1A3, d), ciliated (FAM183B, e), or secretory (OVGP1, f) cells 1, 30, and 360 DPI. cf Two way ANOVA with the Tukey’s multiple comparison post hoc test for all distal regions. c ***P = 0.0003, ****P < 0.0001 (d) ****P < 0.0001 (e) ****P < 0.0001 (f) *P = 0.0146, **P = 0.0058, ****P < 0.0001. Data are presented as mean values ± SD. Biological replicates (mice, n): c Distal 1 DPI n = 6, 30 DPI n = 4, 360 DPI n = 3; Proximal 1 DPI n = 4, 30, and 360 DPI n = 3 each group. d Distal and Proximal n = 3 each group. e Distal 1 DPI n = 6, 30 DPI and 360 DPI n = 4 each group; Proximal 1 DPI n = 4, 30, and 360 DPI n = 3 each group. f Distal 1 DPI n = 6, 30, and 360 DPI n = 4 each group; Proximal n = 3, each group.
