Abstract
Human basement membrane matrix is provided, produced by a novel tumorigenic cell line, where the basement membrane can be used for the growth of a variety of cells, in culture and in vivo. Other cell lines are provided, which may serve to evaluate in vivo the response of tumorigenic cells to various agents, including basement membrane. The basement membrane finds use in allowing the growth of cells in culture and in vivo, particularly cells which are otherwise refractory to xenografting.
Claims3
A method for growing human tumorigenic cells in an immunocompromised mammal host, said method comprising:
- introducing said tumorigenic cells into said mammal host mixed with a basement membrane like composition derived from basement membrane produced by HMS-X cells and comprising from 20-30 weight % heparan/chondroitin sulfate proteoglycan, from about 10-20 weight % fibronectin, 2-10 weight % laminin, about 10 weight % nidogen/entactin and from about 2-10 weight % of each of type I and IV collagen;
- and
- growing said mammal host for sufficient time for said tumorigenic cells to grow.
