It has been shown in animal models that hepatocytes and cholangiocytes can derive from bone marrow cells. We have investigated whether such a process occurs in humans. Archival autopsy and biopsy liver specimens were obtained from 2 female recipients of therapeutic bone marrow transplantations with male donors and from 4 male recipients of orthotopic liver transplantations from female donors. Immunohistochemical staining with monoclonal antibody CAM5.2, specific for cytokeratins 8, 18, and 19… 
No Evidence for Recipient-Derived Hepatocytes in Serial Biopsies of Sex-Mismatched Liver Transplants
TLDR
It is thought that recipient BM-HSC–derived hepatocyte repopulation is a very rare event at best and is not of clinical relevance, and there was no evidence for recipient-derived hepatocytes in liver transplants at any time point.
Liver biopsies from human females contain male hepatocytes in the absence of transplantation
TLDR
Male cells found in livers of women with sons include cells that express hepatocyte antigens, suggesting that transplantation and stem cell differentiation studies using sex difference to conclude that donor cells regenerate liver may be confounded by fetal microchimerism.
Bone marrow engraftment in a rodent model of chemical carcinogenesis but no role in the histogenesis of hepatocellular carcinoma
TLDR
The results suggest that hepatic stem cells derived from the bone marrow have low malignant potential, at least in this model of chemical hepatocarcinogenesis.
Adult liver stem cells: bone marrow, blood, or liver derived?
TLDR
In both studies, female bone marrow transplant recipients receiving male donor cells and males transplanted with female donor livers were examined; the fate of the donor marrow derived cells and the host haematopoietic stem cells in the latter were followed by identifying male derived cells in histological sections of livers using molecular probes specific for the Y chromosome.

Bone marrow contributes to renal parenchymal turnover and regeneration
TLDR
The presence of bone marrow‐derived cells was noted in both histologically normal mouse kidneys and in human transplanted kidneys suffering damage from a variety of causes, indicating that bone marrow cells contribute to both normal turnover of renal epithelia and regeneration after damage, and is suggested that this could be exploited therapeutically.
Hepatocytes and epithelial cells of donor origin in recipients of peripheral-blood stem cells.
TLDR
All six recipients of sex-mismatched transplants showed evidence of complete hematopoietic donor chimerism and the presence of donor cells in the biopsy specimens did not seem to depend on the intensity of tissue damage induced by graft-versus-host disease.
Bone marrow stem cells contribute to alcohol liver fibrosis in humans.
Bone marrow-derived stem cell (BMSC) contribution to liver repair varies considerably and recent evidence suggests these cells may contribute to liver fibrosis. We investigated the mobilization and
Bone marrow derivation of pericryptal myofibroblasts in the mouse and human small intestine and colon
TLDR
The data indicate that bone marrow cells contribute to the regeneration of intestinal myofibroblasts and epithelium after damage, and it is suggested that this could be exploited therapeutically.
Human cord blood CD34+ cells develop into hepatocytes in the livers of NOD/SCID/γcnull mice through cell fusion
TLDR
Results show that human CD34+ cells fuse with hepatocytes of NOG mice without liver injury, lose their hematopoietic phenotype, and begin hepatocyte‐specific gene transcription, phenomena that were not observed when CD34− cells were transplanted.

Derivation of hepatocytes from bone marrow cells in mice after radiation‐induced myeloablation
TLDR
It is concluded that hepatocytes can derive from bone marrow cells after irradiation in the absence of severe acute injury, and the small subpopulation of CD34+lin−Bone marrow cells is capable of such hepatic engraftment.
Immunolocalization of putative human liver progenitor cells in livers from patients with end-stage primary biliary cirrhosis and sclerosing cholangitis using the monoclonal antibody OV-6.
TLDR
It is proposed that the small OV-6-positive oval cells are analogous to those seen in rat models and may represent human liver progenitor cells that may differentiate into OV/CK-19-positive ductal cells or lobular hepatocytes.
The canals of hering and hepatic stem cells in humans
TLDR
The 3‐dimensional structure of ductular reactions in massive necrosis suggests that these reactions are proliferations of the cells lining the CoH, which consists of, or harbor, facultative hepatic stem cells in humans.
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.
Expression of the stem cell factor receptor c‐kit in normal and diseased pediatric liver: Identification of a human hepatic progenitor cell?
TLDR
The up‐regulation of c‐kit receptor expression in diseased livers suggests an involvement of this receptor/ligand system in hepatic repair mechanisms, and it is speculated that c‐Kit–positive cells may represent a hepatic progenitor cell population.

TLDR
The search for liver stem or progenitor cells has a long history, but there is now sufficient evidence to indicate that such cells do exist in adult animals and probably also in humans, and this work has now been extended to encompass work in fetal and adult normal livers as well as acutely injured liver.

TLDR
It is concluded that there is a primitive stem cell type in the liver (type 0) that may differentiate directly into type I and then into type II, duct‐like or or type III hepatocyte‐like cells.
Expression of cytokeratins in normal and diseased livers and in primary liver carcinomas.
TLDR
It is suggested that hepatocytes and bile duct epithelium retain their distinct cytokeratin profiles in liver disease, including malignant transformation, which is useful in establishing the cellular origin of neoplasms and understanding the pathogenesis of liver diseases.
