Abstract: A biopsy site marker includes a carrier and a marker element. The marker element is disposed within the carrier. The carrier including a first marker material and a second marker material. The first marker material and the second marker material are each configured to expand in the presence of moisture. The first marker material is configured to expand at a rapid rate relative to the second marker material in the presence of moisture.

Abstract: The present invention concerns bioactive renal cell populations, in particular a B2 cell population comprising an enriched population of tubular cells and wherein the renal cell population is depleed of a B1 cell population, renal cell constructs, and methods of screening test agents using the bioactive renal cell populations.

Abstract: Hepatic progenitors comprise two populations of human hepatic stem cells, primitive and proximal hepatic stem cells, and two populations of committed progenitors, one for biliary cells and one for hepatocytes. Human primitive hepatic stem cells are a very small fraction of the liver cell population and give rise to proximal hepatic stem cells constituting a much larger fraction of the liver. Human proximal hepatic stem cells give rise to biliary and hepatocyte committed progenitors. Primitive and proximal stem cells are the primary stem cells for the human liver. Human primitive hepatic stem cells may be isolated by immunoselection from human livers or culturing human liver cells under conditions which select for a human primitive hepatic stem cell. Proximal hepatic stem cells may be isolated by immunoselection, or by culturing human liver cells under conditions which include a developmental factor.
