Cord Blood Lin−CD45− Embryonic-Like Stem Cells Are a Heterogeneous Population That Lack Self-Renewal Capacity
Figure 6
Lin−CD45− cells show a high nuclear/cytoplasm ratio.
(A) Immunocytochemistry shows small cells (≦10 µm) with high nuclear (blue)/cytoplasm ratio positive for CD34 (red). (B) Note one CD34-positive and one CD34–negative cell and an example of cell debris present in the sample (arrow). (C) Rare SSEA-4–positive cell. Scale bars = 10 µm (A–B) and 5 µm (C).
