CD34 and breast cancer: Using ADSCs isolated from adipose tissues adjacent to breast tumors of breast cancer patients, we were able to demonstrate that the isolated ADSCs showed plastic adherence, expressed mesenchymal and stemness markers and displayed multipotency in both flow cytometry (positive for CD90, CD105, and CD44, and negative for CD34 and CD45) and differentiation assays for adipogenesis, osteogenesis, and chondrogenesis (Figure 1).
