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.

Increased Bone Adiposity and Peroxisomal Proliferator-Activated Receptor-γ2 Expression in Type I Diabetic Mice

TL;DR: A streptozotocin-induced diabetic mouse model is used to examine the effect of type I diabetes on bone and proposes a second mechanism contributing to diabetic bone loss: increased marrow adiposity.

Regeneration in vertebrates.

TL;DR: The different types of regeneration in vertebrates and their basic characteristics are presented and the major cellular events, such as dedifferentiation and transdifferentiation, which allow complex organ and body part regeneration, are discussed.

Development of Liver Decellularized Extracellular Matrix Bioink for Three-Dimensional Cell Printing-Based Liver Tissue Engineering.

TL;DR: The proposed liver dECM bioink is a promising bioink candidate for 3D cell printing-based liver tissue engineering and induces stem cell differentiation and enhance HepG2 cell function.

SDF-1α/CXCR4: A Mechanism for Hepatic Oval Cell Activation and Bone Marrow Stem Cell Recruitment to the Injured Liver of Rats

TL;DR: Light is shed on a possible mechanism, which may someday lead to a better understanding of the hepatic and hematopoietic interaction in oval cell aided liver regeneration, by which the oval cell compartment could be activated and possibly recruit a second wave of bone marrow stem cells to the injured liver.

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.
