doi: 10.1038/s41598-023-41708-y
Figure Lengend Snippet: ( a ) Histograms showing expression of CD1a, CD1b, CD1c, and CD1d by total thymocytes. ( b ) Dot plot showing the five developmental stages, defined according to expression of CD3 and CD1b, and a graph showing the percentage of cells at each developmental stage. ( c–g ) Dot plots showing CD4/CD8 expression patterns at each developmental stage. The red box in panel d denotes the ISP stage, and the red box in panel f denotes the CD4 hi CD8 lo intermediate stage. ( h ) Dot plots and graphs showing expression of intracellular TCR Vβ and CD28 according to developmental stage (up to CD3 lo CD1b + DP stage). ( i ) Dot plots showing CD4/CD8 expression by CD3 hi thymocytes. ( j ) A contour plot showing CD1b + and CD1b − thymocytes among CD3 hi CD4/CD8 SP thymocytes. ( k ) A contour plot showing CD1b + and CD1b − thymocytes among CD3 hi DP thymocytes and a histogram comparing CD1b expression levels by DP thymocytes at each developmental stage. This histogram uses the modal option to scale all channels as a percentage of the maximum count. ( l ) A schematic diagram showing the order of the developmental stages of thymocytes, based on the expression of CD1b. Each number indicates the following stage: (I) CD3 - CD1b - DN, (II) CD3 - CD1b + DN, (III) CD3 - CD1b + ISP, (IV) CD3 - CD1b + DP and CD3 lo CD1b + DP, (V) CD3 hi CD1b + DP, (VI) CD3 hi CD1b + SP, mCD4 SP: CD3 + CD1b - mature CD4 SP, mCD8 SP: CD3 + CD1b - mature CD8 SP, mDP: CD3 + CD1b - mature DP. Data are representative of six independent experiments, each with a similar result. Data are expressed as the mean ± SD (n = 6). * p < 0.05; ** p < 0.01. i.c.: intracellular.
