Angiogenesis: the role of PDGF-BB on adipose-tissue derived stem cells (ASCs).

Recently, it was shown that mesenchymal stem cells (MSCs) are capable of differentiating into endothelial cells which highlights the potential role of MSCs in neovascularization. In the present study, we investigated the paracrine factors responsible for tube formation in human adipose-tissue derived stem cells (ASCs). Moreover, we analyzed ASC's migration towards PDGF-BB and altered levels of proteins involved in different pathways.

Giant gluteal lipoma-like liposarcoma: a case report.

Background: Liposarcoma is the second most common soft tissue sarcoma in adults with a peak incidence between the 4th and 6th decade of life and slight preponderance to the male gender. It originates from multipotential primitive mesenchymal cells, rather than mature adipose tissue.

Case Presentation: An unusual case of a rapidly growing giant lipoma-like liposarcoma of the left gluteal and perineal areas in a young male was presented.
