First Claim
Patent Images
1. A method for isolating progenitor cells from a bile duct comprisingculturing a bile duct explant comprising both an epithelial layer and a stromal layer, which explant retains in culture the original epithelial-mesenchymal microarchitecture of a mammalian bile duct, wherein said explant is maintainable in culture for at least twenty-four hours, and wherein said explant includes at least on progenitor cell which has the ability to proliferate;
- contacting said explant with an agent which causes proliferation of progenitor cells in said explant; and
isolating from said explant progenitor cells that proliferate in response to said agent.
