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.

Multipotent skin-derived precursors: adult neural crest-related precursors with therapeutic potential

TL;DR: The idea that SKPs are neural crest-related precursors that migrate into the skin during embryogenesis, persist within a specific dermal niche, and play a key role in the normal physiology, and potentially pathology, of the skin is discussed.

Liver stem cells and prospects for liver reconstitution by transplanted cells

TL;DR: This review is limited to studies directed toward identification of hepatic epithelial stem cells and does not address the controversial issue of whether stem cells derived from the bone marrow have hepatocytic potential.

Stem cell plasticity — building the brain of our dreams

TL;DR: Focusing on the nervous system, the evidence that adult neural stem cells are highly plastic, and that other types of adult non-neural stem cells can generate neural progeny, is reviewed to provide a balanced view of the evidence.

Generation of human hepatocytes by stem cell technology: definition of the hepatocyte.

TL;DR: The present article reviews studies describing the fate of extrahepatic human stem and precursor cells in livers of laboratory animals, including the possibility of cell fusion and critically discusses the phenotype of stem cells after application of various differentiation protocols aimed at generating human hepatocytes.

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.
