Low pH preconditioned amniotic epithelial cells for stem cell therapy of cancer
Amniotic epithelial cells (AECs) possess unique characteristics, which make them a suitable source for cell-based therapeutic strategies. AECs have stem cell properties with low-immunogenicity (due to expressing HLA-G molecule and absence of MHC class I and II antigens) and no ethical problems, as well as availability in sufficient numbers, which can be obtained from a placenta. We have recentl...
متن کاملMesenchymal Stem Cells Trigger Epithelial to Mesenchymal Transition in the HT-29 Colorectal Cancer Cell Line
Background and Objective: Mesenchymal stem cells (MSCs) promote metastasis in colorectal cancer; however, the mechanism underlying this process is not fully understood. Epithelial to mesenchymal transition (EMT) is a key step in tumor acquisition of metastatic phenotype. We aimed to investigate the effect of MSCs on the expression of EMT markers, as well as cancer stem cell markers in HT-29 col...
متن کاملOcular surface epithelial and stem cell development.
Phenotypic features and developmental events involved in the genesis of the limbo-corneal and conjunctival epithelia are described. Together, these two epithelia define the ocular surface. They derive from a small cohort of optic vesicle-induced PAX6+ head ectodermal cells that remain on the surface following lens vesicle formation by the main PAX6+ cell cohort. Both epithelia are stratified, a...
متن کاملStem cell characteristics of amniotic epithelial cells.
Amniotic epithelial cells develop from the epiblast by 8 days after fertilization and before gastrulation, opening the possibility that they might maintain the plasticity of pregastrulation embryo cells. Here we show that amniotic epithelial cells isolated from human term placenta express surface markers normally present on embryonic stem and germ cells. In addition, amniotic epithelial cells e...
متن کاملS13-05 Harnessing epithelial stem cell potency
naling events that are continuously modified by environmental cues. However, the details of how these processes can change cell fate choices are still unknown. Previously, we demonstrated that sustained expression of HOXA3 both accelerated wound healing and promoted neovascularisation in diabetic mice. We have subsequently shown that in response to injury HOXA3 induces a significant increase in...
