Bone marrow as a potential source of hepatic oval cells.

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.

How cells change their phenotype

TL;DR: This review examines recently discovered cases of metaplasia, and speculates on the potential molecular and cellular mechanisms that underlie the switches, and their significance to developmental biology and medicine.

Mesenchymal stem cells that produce neurotrophic factors reduce ischemic damage in the rat middle cerebral artery occlusion model.

TL;DR: MSC transfected with the BDNF or GDNF gene resulted in improved function and reduced ischemic damage in a rat model of MCAO, suggesting that gene-modified cell therapy may be a useful approach for the treatment of stroke.

Endometrial stem/progenitor cells: the first 10 years

TL;DR: The discovery of specific markers for endometrial stem/progenitor cells has enabled the examination of their role in endometrian proliferative disorders, including endometriosis, adenomyosis and Asherman's syndrome.

Heterogeneity and plasticity of hepatocyte lineage cells

TL;DR: Experimental models of liver injury and of hepatocarcinogenesis may call forth a cellular response at different levels in the hepatic lineage, and these cells have different potential to form cells of other types (plasticity).

Muscle Regeneration by Bone Marrow-Derived Myogenic Progenitors

TL;DR: Transplantation of genetically marked bone marrow into immunodeficient mice revealed that marrow-derived cells migrate into areas of induced muscle degeneration, undergo myogenic differentiation, and participate in the regeneration of the damaged fibers.

In vivo differentiation of rat liver oval cells into hepatocytes.

TL;DR: The data indicate that oval cells can differentiate to hepatocytes and may have an important physiological function as a source of major serum proteins when hepatocytes are unable to synthesize these proteins.

Presence of hematopoietic stem cells in the adult liver

TL;DR: The data obtained from the mouse study strongly suggest that hematopoietic stem cells residing in the donor liver are responsible for mixed chimerism and maintenance of tolerance after liver transplantation.

Expression of stem cell factor and its receptor, c-kit, during liver regeneration from putative stem cells in adult rat.

TL;DR: The SCF/c-kit system may, possibly in combination with other growth factor/receptor systems, be involved in the early activation of the hepatic stem cells as well as in the expansion and differentiation of oval cells.

Variable chimerism, graft-versus-host disease, and tolerance after different kinds of cell and whole organ transplantation from Lewis to brown Norway rats.

TL;DR: Both the GVHD propensity and tolerogenicity in these experiments were closely associated with recipient tissue chimerism 30 and 100 days after the experiments began, and these observations provide guidelines that should be considered in devising leukocyte augmentation protocols for human whole organ recipients.
