Subpopulations of spore-like cells expressing specific cell surface and gene expression markers are provided. In one embodiment, the cells express at least one cell surface or gene expression marker selected from the group consisting of Oct4, nanog, Zfp296, cripto, Gdf3, UtF1, Ecat1, Esg1, Sox2, Pax6, nestin, SCA-1, CD29, CD34, CD90, B1 integrin, cKit, SP-C, CC10, SF1, DAX1, and SCG10. Also provided are methods for purifying a subpopulation of spore-like cells of interest from a population of spore-like cells, and methods for inducing differentiation of the isolated spore-like cells into cells of endodermal, mesodermal or ectodermal origin. The spore-like cells can be used to generate cells originating from all three germ layers and can be used to treat a patient who has a deficiency of functional cells in any of a wide variety of tissues, including the retina, intestine, bladder, kidney, liver, lung, nervous system, or endocrine system.
An isolated sub-population of spore-like cells expressing one or more markers selected from the group consisting of zinc finger protein 296 (Zfp296), cryptic family protein 1B(crypto), growth differentiation factor-3 (Gdf3), undifferentiated embryonic cell transcription factor 1 (UtF1), embryonic stem cell associated transcript 1 (Ecat1), embryonic stem cell-specific gene 1 (Esg1), sex determining region Y-box 2 (Sox2), paired box protein 6 (Pax6), stem cell antigen 1(SCA-1), cluster of differentiation protein 29 (CD29), cluster of differentiation protein 34 (CD34), cluster of differentiation protein 90 (CD90), B1 integrin, tyrosine-protein kinase (cKit), surfactant protein C (SP-C), Clara cell 10 protein (CC10), splicing factor 1 (SF1), dosage-sensitive sex reversal gene 1 (DAX1), and superior cervical ganglion-10 protein (SCG10), wherein the spore-like cells that remain viable following oxygen deprivation for at least four hours are isolated to form the isolated sub-population of spore-like cells.
A method of isolating a subpopulation of spore-like cells comprising the steps of:
