Figure Lengend Snippet: A BMDCs were stained with the anti-Jagged1 antibody. The expression level of Jagged1 in BMDCs was examined using FCM after stimulation with different concentrations of LPS for 6 h. B The expression level of Jagged1 in BMDCs after stimulation with LPS (100 ng/ml) for different durations was detected using FCM. C Representative images of the expression of Notch3 (green fluorescence) and cytokeratin 8 (K8, a cTEC marker, red fluorescence) in the thymus from different aged mice (2–3 weeks old, 6–8 weeks old, and 10 months old, respectively) were captured by immunofluorescence microcopy. Paraffin sections of the thymus obtained from different aged mice were stained with primary rabbit anti-Notch3 and rat anti-cytokeratin 8 antibodies, followed by secondary Alexa Fluor 488-labeled goat anti-rabbit and Alexa Fluor 555-labeled goat anti-rat antibodies, respectively. Finally, the sections were stained with DAPI. Scale bars represent 200 µm. D mTEC1 cells were stained with PE-conjugated anti-Notch3 antibody. The expression of Notch3 in mTEC1 cells was detected by FCM. All data are from three independent experiments. Representative figures of these three experiments are displayed.

Figure Lengend Snippet: A rmJagged1-hFc was precoated on a 24-well plate at 4 °C for 12 h. BSA precoated at the same concentration was used as the control. mTEC1 cells were seeded at a density of 6 × 10 4 cells per well. Cell apoptosis was examined through staining with Annexin V/PI. B L and J cells were pre-stained with CFSE. mTEC1 cells were then cocultured with L or J cells at a 1:3 ratio for 48 h. The apoptosis of mTEC1 cells was examined through staining with Annexin V-APC/7-AAD. C The different concentrations of rmJagged1-hFc were precoated on 96-well plates at 4 °C for 12 h. The same concentration of BSA was set as the control group. mTEC1 cells were seeded at a density of 5 × 10 3 cells per well. Cell proliferation was examined using an EdU incorporation assay after 48 h. The red fluorescent dots indicate proliferating cells. Scale bars represent 200 µm. D The percentages of red fluorescent dots in all cells were calculated according to panel C . E Experiments were performed as described in A . mTEC1 cells were treated with or without DAPT (10 μM). Cell apoptosis was analyzed through Annexin V/PI staining. F Experiments were performed as described in C . Proliferation was detected by performing an EdU incorporation assay. mTEC1 cells were incubated with or without DAPT (10 μM). Red fluorescent dots indicate proliferating cells. Scale bars represent 200 µm. G The percentages of red fluorescent dots in all cells were calculated according to panel F . H Experiments were performed as described in B . mTEC1 cells were treated with or without DAPT (10 μM). I Experiments were performed as shown in Fig. . mTEC1 cells were cultured with or without DAPT (10 μM). J Experiments were performed as shown in Fig. . mTEC1 cells were treated with or without DAPT (10 μM). Scale bars represent 200 µm. K The percentages of red fluorescent dots in all cells were calculated according to panel J . All data are from three independent experiments. Representative figures of these three experiments are shown. Data are expressed as the mean ± SD. ** P < 0.01, *** P < 0.001 compared with the control group.

B Total numbers of thymocytes were calculated. C Thymocytes were stained with PE-conjugated anti-CD4 and APC-labeled anti-CD8 antibodies. The thymocyte subpopulations were analyzed by FCM. D The percentages and absolute numbers of the indicated thymocyte populations were calculated. E The cells isolated from the thymus of recipient mice were stained with Alexa Fluor 488-conjugated anti-CD45 and APC-labeled anti-EpCAM antibodies, respectively. CD45 - EpCAM + TECs were evaluated by FCM. F The percentages and absolute numbers of CD45 - EpCAM + cells were calculated. All data are from three independent experiments. Representative figures of these three experiments are shown. Data are represented as the mean ± SD. * P < 0.05, *** P < 0.001 compared with the control group.

Figure Lengend Snippet: Circulating mDCs can return to the thymus where they interact with TECs through direct cell–cell contact. MDCs can activate Notch signaling in TECs through the Jagged1/Notch3 axis. Long-term Notch signaling activation of TECs results in apoptosis and growth inhibition, further leading to the degeneration of the thymus.
