a Representative FACS plots showing expression of UEA1 and Ly51 by total EpCAM1+ cells, K19-EpCAM1+ cells and K19+EpCAM1+ cells at E15.5, and corresponding quantitation (n = 12, from 3 independent experiments). Data analysed using a Student’s t-test. b Representative FACS plots showing expression of MHCII and CD80 to define mTECneg (MHCII-CD80-), mTECint (MHCIIintCD80int) and mTEChi (MHCIIhiCD80hi), and the corresponding expression of K19 by these subsets (upper panel), and expression of Aire within mTEChi, and the corresponding expression of K19 by Aire+ mTEChi (lower panel). Bar chart shows proportion of K19+ cells within mTECneg, mTECint, and mTEChi at E15.5 (n = 12, from 3 independent experiments). Data analysed using a one-way ANOVA, with Bonferroni post hoc test. c Representative FACS plots showing expression of MHCII within UEA1-Ly51+ cells, and expression of K19 by these subpopulations. Bar chart shows proportion of K19+ cells within MHCII-UEA1-Ly51+ and MHCII+UEA1-Ly51+ TEC at E15.5 (n = 12, from 3 independent experiments). Data analysed using a Student’s t test. The data are shown as mean ± SEM.
