Figure 6From: Human CD8 T cells generated in vitro from hematopoietic stem cells are functionally matureCharacterization of single-positive T cells generated from HSC/OP9-DL1 coculture. Flow cytometric analysis for cell surface expression of CD4 and CD8 is presented for 2 independent cocultures (left side). CD27 expression was examined on CD4+ CD8--gated cells (solid black line) and on CD4- CD8+-gated cells (shaded histogram).Back to article page
