Stromal pleiotrophin regulates repopulation behavior of hematopoietic stem cells.
Pleiotrophin (Ptn) is strongly expressed by stromal cells which maintain HSCs. However, in vivo, Ptn deficiency does not alter steady-state hematopoiesis. However, knockdown of Ptn (Ptn(KD)) in stromal cells increases production of hematopoietic progenitors as well as HSC activity in cocultures, suggesting that Ptn may have a role in HSC activation. Indeed, transplantations of wild-type (Ptn(+/...
متن کاملThe repopulation potential of fetal liver hematopoietic stem cells in mice exceeds that of their liver adult bone marrow counterparts.
Varying, limiting numbers of unseparated or purified cells (Ly-5.1), either from 14.5-day-old fetal liver (FL) or from adult bone marrow (BM) were coinjected with 10(5) unseparated BM cells (Ly-5.2) into lethally irradiated adult C57B1/6 recipients (Ly-5.2). The kinetics of donor cell repopulation of the lymphoid and myeloid compartments by Ly-5.1+ donor hematopoietic stem cells (ie, competitiv...
متن کاملMurine embryonic stem cell-derived hepatocytes correct metabolic liver disease after serial liver repopulation.
Although embryonic stem (ES) cell-derived hepatocytes have the capacity for liver engraftment and repopulation, their in vivo hepatic function has not been analyzed yet. We aimed to determine the metabolic function and therapeutic action of ES cell-derived hepatocytes after serial liver repopulations in fumaryl acetoacetate hydrolase knockout (Fah(-/-)) mice. Albumin expressing (Alb(+)) cells w...
متن کاملSelection of hepatocyte-like cells from mouse differentiated embryonic stem cells and application in therapeutic liver repopulation.
UNLABELLED BACKGROUD/AIM: Because of the oncogenic risk, it is important to gain the homogeneous and purified cells from differentiated ESCs before transplantation. Here, we aim to select hepatocyte-like cells from differentiated ESCs, and investigate their growth, differentiation and neoplastic formation after intrahepatic transplantation. METHODS Mouse ESCs were primarily induced by Dexamet...
متن کاملLiver Cancer Stem Cells
Hepatocellular carcinoma is the most common primary malignancy of the liver in adults. It is also the fifth most common solid cancer worldwide and the third leading cause of cancer-related death. Recent research supports that liver cancer is a disease of adult stem cells. From the models of experimental hepatocarcinogenesis, there may be at least three distinct cell lineages with progenitor pro...
