MenSCs promote angiogenesis
. (A) Matrigel was mixed with cells (3 × 106 cells/plug) or DMEM alone and subcutaneously injected into mice. After 14 days, the matrigel plugs were harvested and photographed. (B) MenSCs have a high hemoglobin content. The hemoglobin content of the plugs from the different groups was measured using Drabkin’s method. The graph represents statistical analysis of the hemoglobin concentration in the matrigel plugs. Values are expressed as mean ± SE (***P ≤0.001). MenSC, menstrual-derived stem cells; SE, standard error.
