Figure 4

Demonstration that ALDH+CD34- cells are early erythroid cells. Blue: ALDH+CD34- cells. Yellow: ALDH+CD34+ cells. Cells were stained with ALDEFLUOR, CD105-PE, CD34-PerCP and CD71-APC. Gate was imposed on ALDH+ cells. In panel A, all CD34- cells are CD105+. In panel B, all CD34- cells are CD71bright. In panel C, CD105 and CD71 are completely co-expressed. Panel D shows that erythroid cells are larger than CD34+ progenitor cells. This case is one representative example of a phenomenon observed in all BM specimens.
