Abstract

Cells derived from human umbilical cords are disclosed along with methods for their therapeutic use. Isolation techniques, culture methods and detailed characterization of the cells with respect to their cell surface markers, gene expression, and their secretion of trophic factors are described.

Claims

wherein said isolated cell self-renews and expands its numbers in culture;

wherein said isolated cell can differentiate into a cell that expresses markers indicative of differentiation into a type selected from the group consisting of neural cells, hepatocytes, adipocytes, pancreatic beta cells, chondrocytes, and cardiomyocytes;

and wherein said isolated cell does not express CD45 or CD117.

2. A cell culture comprising the isolated cell of claim 1 wherein said culture expands in the presence of about 5% to about 20% oxygen.

3. The isolated cell of claim 1, wherein said isolated cell maintains a normal karyotype upon passaging.
