Compositions and methods for generating skin
First Claim
1. A population of isolated mammalian or avian multipotent spore-like cells (MSLCs) isolated or cultured from skin tissue and which can differentiate into two or more mature skin cell type cells.wherein the MSLCs, when first isolated, are approximately one to ten microns in diameter,wherein the MSLCs are viable following essentially complete oxygen-deprivation for twenty four hours or more,wherein the MSLCs are surrounded by an outer membrane that is rich in glycolipids and mucopolysaccharides so that the MSLCs appear to have one or more dark stripes when viewed by transmission electron microscopy, andwherein nucleic acids account for at least about 50% of the volume of each spore-like cell within the population.

9. A method for isolating a multipotent spore-like cell (MSLC population from a post-natal mammal, the method comprising
passing a piece of skin obtained from the mammal through a series of devices having progressively smaller apertures to isolate a population of MSLCs, wherein the MSLCs, when first isolated, are approximately one to ten microns in diameter; - and are viable following essentially complete oxygen-deprivation for twenty four hours or more, surrounded by an outer membrane that is rich in glycolipids and mucopolysaccharides, and wherein nucleic acids account for at least about 50% of the volume of each spore-like cell within the population, and wherein the MSLC can differentiate into two or more mature skin cell types.
