Some molecular and genetic properties of progenitor cells in sarcomas induced with foreign body

Some molecular and genetic properties of progenitor cells in sarcomas induced with foreign body One of the important questions in understanding the mechanisms of carcinogenesis induced with foreign body (or plastic carcinogenesis), is a question about normal progenitor cells in sarcomas (FB sarcomas) appearing in close proximity to the plastic plate implanted under the skin of an experimental animal. There is an assumption in literature that progenitor cells in FB sarcomas originate from vascular endothelium cells feeding a connective tissue capsule that forms around foreign body. In our research, we studied mRNA expression of one of the endothelial cell markers—receptor VEGFR2/Flk1—and growth factor VEGF-A, which interacts with it, in precancerous cells of FB sarcomas in mice. In examined cells, mRNA expression of VEGF-A was found while mRNA expression of VEGFR2/Flk1 was absent. In light of this and formerly established properties of progenitor cells in FB sarcomas, possibilities of the origin of these sarcomas from endothelial cells, pericytes, and pluripotent mesenchymal stem cells are being discussed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Developmental Biology Springer Journals

Abstract

One of the important questions in understanding the mechanisms of carcinogenesis induced with foreign body (or plastic carcinogenesis), is a question about normal progenitor cells in sarcomas (FB sarcomas) appearing in close proximity to the plastic plate implanted under the skin of an experimental animal. There is an assumption in literature that progenitor cells in FB sarcomas originate from vascular endothelium cells feeding a connective tissue capsule that forms around foreign body. In our research, we studied mRNA expression of one of the endothelial cell markers—receptor VEGFR2/Flk1—and growth factor VEGF-A, which interacts with it, in precancerous cells of FB sarcomas in mice. In examined cells, mRNA expression of VEGF-A was found while mRNA expression of VEGFR2/Flk1 was absent. In light of this and formerly established properties of progenitor cells in FB sarcomas, possibilities of the origin of these sarcomas from endothelial cells, pericytes, and pluripotent mesenchymal stem cells are being discussed.
