Supplementary Figure 2: Runx3d expression during MHC I positive selection.

Runx3d-YFP expression in CD69⁺DP, IM₁, IM₂, IM₃, and SP8 thymocytes from OT-I Rag2^−/− Runx3d^YFP mice is displayed (left panels). CCR7 expression on gated Runx3d-YFP⁻ and Runx3d-YFP⁺ cells is also displayed (right panels).
