Abstract
The aim of this review is to summarize and give an overview on the findings of signaling between hepatic and hematopoietic progenitors of the liver. To date, there are not many findings published in the field, and the aim of this review is to cover all current publications in this area. The liver is the main site of hematopoiesis during fetal development. However, little is known about how hepatic and other non-hematopoietic progenitors potentially influence hematopoiesis and vice versa. The concurrent peaks of hepatic and hematopoietic progenitor proliferation during development indicate interactions that could possibly be mediated through cell-cell contact, extracellular matrices, cytokines and growth factors, or other signaling molecules. For example, hepatic progenitors, such as hepatic stem cells and hepatoblasts, possess characteristic surface markers that can be cleaved, giving rise to fragments of various lengths. A surface molecule of hepatoblasts has been demonstrated to play an essential role in hematopoiesis. Particularly, these effects on hematopoiesis were distinct, depending on whether it was membrane-bound or cleaved. In this review, the various hepatic and hematopoietic progenitor cell types are concisely described, and the current findings of their potential interactions are summarized.

Abstract
Biliary atresia (BA) is a rare and serious liver disease in newborn infants. Previously, we reported that non-parenchymal cell (NPC) fractions from cirrhotic liver of BA may contain hepatic stem/progenitor cells in primary culture of NPC fractions. In this study, NPC fractions were subjected to primary or passage culture and found that clusters of hepatocyte-like cells appear even without adding hepatocyte growth factor (HGF) to the culture medium, but not in their passage culture used as a control. Based on these findings, conditioned media (CMs) were collected and soluble factors in the CMs were analyzed in order to elucidate the mechanism of the appearance of hepatocyte-like cells or their clusters. A large amount of active HGF consisting of α and β chains was detected in CMs derived from primary culture, but not in CMs from passage culture, as determined by western blot analysis, bone morphogenetic protein (BMP)-4, oncostatin M (OSM), and transforming growth factor (TGF)-β1 were not detected in any of the CMs. The number of hepatocyte-like cells in primary culture tended to decrease following treatment with the HGF receptor c-Met inhibitor, SU11274 in a dose-dependent manner. Furthermore, the clusters of hepatocyte-like cells tended to increase in size and number when freshly isolated NPC fractions were cultured in the presence of 10% of CMs collected after 3-4 wk of primary culture. In conclusion, these findings indicate that CMs derived from primary culture of NPC fractions of BA liver contain a large amount of active HGF, which may activate hepatic stem/progenitor cells and promote the appearance of hepatocyte-like cells or their clusters through HGF/c-Met signaling. The present study would lead to cell therapy using the patient's own cells for the treatment of BA.

Abstract
We sought to determine whether hepatic progenitor cells can be isolated from cirrhotic liver using epithelial cell adhesion molecule (EpCAM) or Thy-1 markers. Liver tissue with cirrhosis secondary to biliary atresia (BA) was collagenase digested, and nonparenchymal cells (NPCs) were cultivated for 24 h. Noncirrhotic NPCs derived from patients with carbamyl phosphate synthetase and ornithine transcarbamylase deficiencies were used as controls. Flow cytometric analysis demonstrated that the percentages of EpCAM- and Thy-1-positive cells were significantly higher in NPC populations derived from BA liver than in those derived from control liver. Reverse transcription polymerase chain reaction analysis revealed that EpCAM-positive sorted cells expressed EpCAM, Thy-1, albumin, and CK-19, whereas Thy-1-positive sorted cells expressed Thy-1, albumin, and CK-19. These findings indicate that EpCAM- or Thy-1-positive hepatic progenitor cells can be more efficiently isolated from BA liver than from control liver and suggest that the properties of EpCAM-positive cells are somewhat different from those of Thy-1-positive cells.

Abstract
The existence of hepatic stem cells in human livers is controversial. We investigated whether the side population (SP) cells derived from an immortalized human liver epithelial cell line THLE-5b possess the properties of hepatic stem-like cells. SP cells derived from THLE-5b were isolated using flow cytometry and were assayed for the expression of phenotypic markers by reverse transcription polymerase chain reaction and immunostaining. THLE-5b SP cells retained the capacity to generate both SP and non-SP cells, showed a capacity for self-renewal, and were more efficient in colony formation than non-SP cells. Neither the SP nor the non-SP cells formed tumors when transplanted into athymic nude mice or severe combined immunodeficient mice. The expression level of stem cell-associated markers such as an ATP-binding cassette membrane transporter, epithelial cell adhesion molecule, c-kit, Thy-1, and octomer binding transcription factor 4 was higher in SP cells than in non-SP cells. When cultivated as rotation-mediated aggregates, the expression of liver-specific genes including tryptophan oxygenase and CYP3A4 was up-regulated in SP cells, suggesting that THLE-5b SP cells have the ability to differentiate into a hepatocyte phenotype. One of the clonal cell lines derived from the SP cells expressed stem cell-associated markers. These results indicate that SP cells derived from THLE-5b possess hepatic stem-like cell properties and suggest that THLE-5b can be used as a model of normal human liver progenitor or stem cell line.

Abstract
If the rapidly progressing field of stem cell research reaches its full potential, successful treatments and enhanced understanding of many diseases are the likely results. However, the full potential of stem cell science will only be reached if all possible avenues can be explored and on a worldwide scale. Until 2009, the US had a highly restrictive policy on obtaining cells from human embryos and fetal tissue, a policy that pushed research toward the use of adult-derived cells. Currently, US policy is still in flux, and retrospective analysis does show the US lagging behind the rest of the world in the proportional increase in embryonic/fetal stem cell research. The majority of US studies being on either a limited number of cell lines, or on cells derived elsewhere (or funded by other sources than Federal) rather than on freshly isolated embryonic or fetal material. Neural, mesenchymal, and the mixed stem cell mononuclear fraction are the most commonly investigated types, which can generally be classified as adult-derived stem cells, although roughly half of the neural stem cells are fetal derived. Other types, such as embryonic and fat-derived stem cells, are increasing in their prominence, suggesting that new types of stem cells are still being pursued. Sixty percent of the reported stem cell studies involved transplantation, of which over three quarters were allogeneic transplants. A high proportion of the cardiovascular systems articles were on allogeneic transplants in a number of different species, including several autologous studies. A number of pharmaceutical grade stem cell products have also recently been tested and reported on. Stem cell research shows considerable promise for the treatment of a number of disorders, some of which have entered clinical trials; over the next few years it will be interesting to see how these treatments progress in the clinic.

Abstract
Primary hepatocellular carcinoma (HCC) is a common malignancy that has a poor prognosis because it is often diagnosed at an advanced stage. HCC normally develops as a consequence of underlying liver disease and is most often associated with cirrhosis. Surgical resection and liver transplantation are the current best options to treat liver cancer. However, problems associated with liver transplantation, such as shortage of donors, risk of immune rejection, and tissue damage following surgery provided the impetus for development of alternative therapies. The emerging field of stem cell therapy has raised hopes for finding curative options for liver cancer. Stem cells have the ability not only to proliferate after transplantation but also to differentiate into most mammalian cell types in vivo. In this review, progress on stem cell-derived technologies for the treatment of liver cancer is discussed.
