Abstract
El aislamiento y proliferacion de células madre, especialmente de las células madre hepáticas continua presentando complicaciones técnicas. Por ejemplo, las colonias de células madre, una vez aisladas, tienden a detenerse, o al menos a proliferar más lentamente. Se provee un método para superar parcialmente esta limitacion. También se describe un método para aislar una nueva célula progenitora hepática. Reivindicacion 1: Una célula progenitora hepática aislada que no expresa la alfa-fetoproteína y que expresa EpCAM y albumina, en donde el nivel de expresion de albumina a expresion de EpCAM de dicho progenitor hepático varía en un rango entre aproximadamente 0,5:1,0 y aproximadamente 0,9:1,0. Reivindicacion 5: Un método para proveer una célula progenitora hepática, que comprende: (a) plaquear una suspension celular individual de células hepáticas sobre una superficie plana e incubar la suspension para permitir que las células hepáticas se adhieran a la superficie plana; (b) propagar las células adherentes en medio HK para obtener una o más colonias de células madre hepáticas, donde cada colonia exhibe un borde; y (c) inclinar la superficie plana en un ángulo y dejar que las células de dichas una o más colonias se propaguen más allá de dicho borde.
