TLDR
A stem cell associated with the bone marrow has epithelial cell lineage capability and a proportion of the regenerated hepatic cells were shown to be donor-derived.Abstract:
Bone marrow stem cells develop into hematopoietic and mesenchymal lineages but have not been known to participate in production of hepatocytes, biliary cells, or oval cells during liver regeneration. Cross-sex or cross-strain bone marrow and whole liver transplantation were used to trace the origin of the repopulating liver cells. Transplanted rats were treated with 2-acetylaminofluorene, to block hepatocyte proliferation, and then hepatic injury, to induce oval cell proliferation. Markers for Y chromosome, dipeptidyl peptidase IV enzyme, and L21-6 antigen were used to identify liver cells of bone marrow origin. From these cells, a proportion of the regenerated hepatic cells were shown to be donor-derived. Thus, a stem cell associated with the bone marrow has epithelial cell lineage capability.read more

Stem cells, cancer, and cancer stem cells
TL;DR: Stem cell biology has come of age: Unequivocal proof that stem cells exist in the haematopoietic system has given way to the prospective isolation of several tissue-specific stem and progenitor cells, the initial delineation of their properties and expressed genetic programmes, and the beginnings of their utility in regenerative medicine.

TL;DR: It is reported here that cells co-purifying with mesenchymal stem cells—termed here multipotent adult progenitor cells or MAPCs—differentiate, at the single cell level, not only into meschymal cells, but also cells with visceral mesoderm, neuroectoderm and endoderm characteristics in vitro.
Journal ArticleDOI
Mesenchymal Stem Cells
TL;DR: The bone marrow contains multipotent MSC, which can be easily isolated and cultured in vitro, and the possibility of their clinical use in cell and gene therapy is analyzed.
Journal ArticleDOI
Mesenchymal stem cells in health and disease
TL;DR: The targets and mechanisms of M SC-mediated immunomodulation and the possible translation of MSCs to new therapeutic approaches are discussed.

TL;DR: It is shown that rare cells that home to bone marrow can LTR primary and secondary recipients, and this finding may contribute to clinical treatment of genetic disease or tissue repair.

Hepatic oval cell activation in response to injury following chemically induced periportal or pericentral damage in rats
TL;DR: The results presented with the 2‐AA/AA model suggest that the periportal matrix may be as important as the cells that populate the area in the oval cell response and AFP gene expression.
Journal ArticleDOI
Tissue architecture: the ultimate regulator of epithelial function?
TL;DR: The role of cell adhesion in the maintenance of tissue structure is discussed and how tissue structure regulates epithelial function is analyzed.
Journal ArticleDOI
Hepatic Stem Cell Compartment: Activation and Lineage Commitment:
TL;DR: The observations that sub-populations of proliferating oval cells phenotypically similar to early hepatoblasts, and that oval cells originate in or around the ductular structures in the portal area, strongly support the notion that the hepatic stem cell compartment resides in these structures.

MULTILINEAGE HEMATOPOIETIC RECONSTITUTION OF SUPRALETHALLY IRRADIATED RATS BY SYNGENEIC WHOLE ORGAN TRANSPLANTATION: With Particular Reference to the Liver1

TL;DR: Direct evidence is presented here direct evidence that supralethally irradiated adult rats can be consistently rescued by syngeneic liver transplantation, and that heart transplantation has a less dramatic but significant therapeutic effect.
Journal Article
Bile ductular damage induced by methylene dianiline inhibits oval cell activation.
TL;DR: Results provide direct evidence that oval cells are closely associated with the biliary epithelial cells and supports the theory that hepatic oval cells may originate from cells derived from either intraportal or periportal ductules.
