Lewis S.Background of Current Research: The Development of the Keratinocyte Lineage from Cultured Human Embryonic Stem Cells
Human embryonic stem cells are able to differentiate in culture and produce numerous somatic cell types.We call the process marker succession.The first problem that presents itself is that hES cells, which give rise to so many somatic cell types, also produce teratomas.In order to free any derived somatic cell type from residual hES cells, it will be necessary to clonally isolate the cell type and expand it to mass culture prior to using it for therapeutic replacement.One should not lose sight of the fact that cultured embryonic stem cells are not embryos.The polarity and the gradients that are important in controlling embryogenesis are absent during the differentiation of cultured hES cells.Optimization of culture conditions improves the proliferation, but not sufficiently to permit their clonal isolation.These cells were easily cloned and grown to mass culture.But for prospective therapeutic purposes, it will be preferable to use other genes capable of improving proliferation without perturbing differentiated function.Our current research is devoted to finding the best solution to this
problem.Derived Cell Types in General
To date, no other somatic cell type derived from hES cells has been reported as clonally isolated.This raises the question whether other somatic cell types derived from hES cells will, like keratinocytes, lack sufficient proliferative potential for investigative or therapeutic use and will have to be genetically modified to improve their proliferation.Regeneration of squamous epithelia from stem cells of cultured grafts.Immortalized keratinocyte lines derived from human embryonic stem cells.Regeneration of Epidermis from Adult Keratinocyte Stem Cells.Hasselbeck, Matt
