Fig. 7. Analysis of renal endothelial cells by flow cytometry. (A-D) YFP labeling of endothelial cells in kidney cell suspensions from a negative control mouse (A), a vav ancestry mouse (B), a chimeric control mouse (C) and a wild-type mouse completely reconstituted with bone marrow of a vav ancestry mouse three months after transplantation (D). The YFP⁺ cells in B correspond to vasa recta endothelial cells. The data shown in A,B were obtained using the MoFlo cell sorter and the LSRII flow cytometer, respectively; hence, the different representation of the YFP intensity.
