Mesenchymal stem cells derived from bone marrow have recently been described to localize to breast carcinomas and to integrate into the tumor-associated stroma. In the present study, we investigated whether adipose tissue-derived stem cells (ASCs) could play a role in tumor growth and invasion. Compared with bone marrow-derived cells, ASCs as(More)
Carcinoma-associated fibroblasts (CAF) are considered to contribute to tumor growth, invasion and metastasis. However, the cell type of origin remains unknown. Since human adipose tissue derived stem cells (hASCs) are locally adjacent to breast cancer cells and might directly interact with tumor cells, we investigated whether CAFs may originate from hASCs.(More)
In the present study, we investigated whether human adipose tissue derived stem cells (hASCs) could enhance tumor invasion and whether these hASCs could be a potential source of CCL5. We observed a significant increase in the number of breast cancer cells that invaded the matrigel when Co-cultured with hASCs. We found that hASCs produce CCL5 in the(More)
BACKGROUND Transplantation of adipose tissue-resident mesenchymal stem cells has been found to contribute to the establishment of a supportive fibrovascular network. The authors sought to evaluate the potential of human adipose tissue-derived stem cells to integrate with nonanimal stabilized hyaluronic acid as a novel injectable soft-tissue filler. (More)
