Figure 2. Binding of annexin V on Lin⁻Sca-1⁺CD45⁻ subpopulations.

Presence of annexin V on surface of cells from Lin⁻Sca-1⁺CD45⁻ subpopulations was evaluated by flow cytometry. Majority of Lin⁻Sca-1⁺CD45⁻c-Kit⁻KDR⁺ and Lin⁻Sca-1⁺CD45⁻c-Kit⁺KDR⁻ were annexin V negative, while more than half of the Lin⁻Sca-1⁺CD45⁻c-Kit⁻KDR⁻ cells were annexin V positive.
