(D) Flow cytometry analysis of CD4+CD8β+ DP, CD3+TCRαβ+ (blue) and CD3+TCRαβ- (red) thymocytes that developed in corresponding cultures from C. Numbers in contour plots indicate the percentage of cells for the corresponding populations. Histograms show TCRγδ expression in CD3+TCRαβ+ (blue) and CD3+TCRαβ- (red) cells.
