Direct intercellular contact between carcinoma cells and adipose-derived stem cells by means of exosomal vesicular exchange was revealed. Breast cancer cells displayed a change towards a more malignant phenotype associated with higher rates of metastasis and worsened prognosis. As cell-assisted lipotransfer is often performed after breast cancer surgery, transfer of adipose-derived stem cells might lead to deterioration of prognosis in case of recurrence as it has been described for inflammatory breast cancer.
