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.

Phenotypic and functional characteristics of mesenchymal stem cells differentiated along a Schwann cell lineage

TL;DR: The assertion that MSCs can be differentiated into cells that are Schwann cell‐like in terms of both phenotype and function is supported.

Bone marrow stromal cells enhance differentiation of cocultured neurosphere cells and promote regeneration of injured spinal cord.

TL;DR: The results suggest that MSCs might have profound effects on the differentiation of neurosphere cells and be able to promote regeneration of the spinal cord by means of grafting.

The Role of Stem Cells in Skeletal and Cardiac Muscle Repair

TL;DR: The contribution of non-myogenic cells to the formation of new postnatal skeletal muscle in vivo appears to be negligible and dermal fibroblasts appear promising as a realistic alternative source of exogenous myoblasts for transplantation purposes.
Journal ArticleDOI

Albumin-expressing hepatocyte-like cells develop in the livers of immune-deficient mice that received transplants of highly purified human hematopoietic stem cells

TL;DR: Evidence is provided that human "hematopoietic" stem/progenitor cell populations have the capacity to respond to the injured liver microenvironment by inducing albumin expression.
Journal ArticleDOI

Kinetics of liver repopulation after bone marrow transplantation.

TL;DR: It is concluded that hepatocyte replacement by bone marrow cells is a slow and rare event and significant liver repopulation was completely dependent on hepatocyte growth selection.

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.
