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.

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.

Blast-like cell compartment in carcinogen-induced proliferating bile ductules.
TL;DR: It is found that a greater diversity of cell types exist within intrahepatic bile ductules of rats treated with carcinogens, and the nonpolarized ductal blast-like cells undergo proliferation and are significantly different in phenotype from other hepatic cells previously reported as candidates for liver progenitor cells.

Coexpression of flt-3 ligand/flt-3 and SCF/c-kit signal transduction system in bile-duct-ligated SI and W mice.
TL;DR: The existence of a compensatory/additive function between the FL/flt-3 and the SCF/c-kit signal transduction systems in hepatic cell biology is postulated.

Use of a rat cDNA probe specific for the Y chromosome to detect male-derived cells.
TL;DR: A cDNA probe that exhibits specificity for the rat Y chromosome was generated by using a set of primers specific to the murine Sry gene, the sex-determining region of the Y chromosome, which should prove useful in studies designed to track cell populations in syngeneic male/female pairs.
A monoclonal antibody (L21-6) recognizing an invariant chain expressed on the cell surface in rats with the exception of the BN (RT1n): a study of tissue and strain distributions.
TL;DR: A unique monoclonal antibody (MAb) was developed, L21-6, recognizing an invariant chain on the cell surface in the rats and studied the tissue and strain distributions.
