CD34⁺CD38⁻ fetal liver cells develop to thymocytes and pDC2 in vivo after intrathymic injection in RAG2^−/− γc^−/− mice with a human thymus transplant.

Sorted CD34⁺CD38⁻ fetal liver cells were labeled with CFSE and injected into the thymus graft. Six weeks after injection, the thymus graft was removed and the cells were labeled with PE-labeled CD4 and CD123 antibodies and TC-labeled CD4, CD8, and CD45RA antibodies. Isotype control antibodies were used to set the cursors.
