Transcription profiling of mouse RLSC and MMH-D3 cell lines

Project description:Increasing evidence provide support that the mammalian liver contains stem/progenitor cells, but their molecular phenotype, embryological derivation, cell biology as well as of their role in the liver cell turnover and regeneration remain to be further clarified. We report the isolation, characterization and reproducible establishment in line of a resident liver stem cell (RLSC) with immunophenotype and differentiative potential distinct from other previously reported liver precursor/stem cells. RLSCs, derived from foetal and neonatal murine livers as well as from immortalized hepatocytic MMH lines and established in lines, are Sca+, CD34-, CD45-, alfa-fetoprotein+, albumin-. This immunophenotype suggests a non-haematopoietic origin. RLSCs transcriptional profile, defined by microArray technology, highlighted the expression of a broad spectrum of âplasticity-related genesâ and âdevelopmental genesâ suggesting a multi-differentiative potential. RLSCs, indeed, spontaneously differentiate into hepatocytes and cholangiocytes and, when cultured in appropriate conditions, into mesenchymal and neuro-ectodermal cell lineages, such as osteoblasts/osteocytes, chondrocytes, astrocytes and neuronal cells. RLSCs capability to spontaneously differentiate into hepatocytes, the lack of albumin expression and the broad differentiative potentiality locate them in a pre-hepatoblast/liver precursor cells hierarchical position. In conclusion, RLSCs may provide an useful tool to improve liver stem cell knowledge and to assess new therapeutic approaches for liver diseases. Experiment Overall Design: We compared the gene expression profile of a RLSC line to that of the previously characterised hepatocytic differentiated cell line MMH-D3 (ref Amicone), using Affymetrix Mouse430_2 GeneChip array.

Hepatocytic parental progenitor cells of rat small hepatocytes maintain self-renewal capability after long-term culture.

Project description:The liver has a variety of functions for maintaining homeostasis, and hepatocytes play a major role. In contrast with the high regenerative capacity of mature hepatocytes (MHs) in vivo, they have not been successfully expanded ex vivo. Here we demonstrate that CD44-positive cells sorted from small hepatocyte (SH) colonies derived from a healthy adult rat liver can proliferate on a Matrigel-coated dish in serum-free chemically defined medium; in addition, a subpopulation of the cells can divide more than 50 times in a period of 17 weeks every 4-week-passage. The passage cells retained the capability to recover highly differentiated functions, such as glycogen storage, CYP activity and bile secretion. When Matrigel-treated cells from the third passage were transplanted into retrorsine/partial hepatectomy-treated rat livers, the cells engrafted to differentiate into MHs and cholangiocytes. These results suggest that long-term cultured CD44+ SHs retain hepatocytic characteristics in vitro and the capability to differentiate into hepatocytes and cholangiocytes in vivo. Thus, a newly identified subpopulation of MHs possessing the attributes of hepatocytic stem/progenitor cells can be passaged several times without losing hepatocytic characteristics.

CINC-2 and miR-199a-5p in exosomes secreted by transplanted Thy1+ cells activate hepatocytic progenitor cell growth in rat liver regeneration

Project description:Small hepatocyte-like progenitor cells (SHPCs) are hepatocytic progenitor cells that transiently form clusters in rat livers treated with retrorsine and with 70% partial hepatectomy (PH). We previously reported that transplantation of Thy1+ cells derived from D-galactosamine-treated livers promotes SHPC expansion, resulting in the acceleration of liver regeneration. Extracellular vesicles (EVs) produced by Thy1+ cells act on sinusoidal endothelial cells (SECs) and Kupffer cells to secrete IL17B and IL25, respectively, resulting in SHPC activation through IL17 receptor B (RB) signaling. Our aim is to identify factors in Thy1-EVs that activate IL17RB signaling. Thy1+ cells isolated from rats with D-galactosamine-induced liver injury were cultured for one week. Although some liver stem/progenitor cells proliferated into colonies, others maintained as mesenchymal cells (MCs). Thy1-MCs or Thy1-liver stem/progenitor cells were transplanted into retrorsine/PHtreated livers to examine their effects on SHPCs. SHs isolated from adult rat livers were used to validate factors regulating growth induction. The number and size of SHPCs remarkably increased in livers transplanted with Thy1-MCs. Comprehensive analysis of Thy1-MC-EVs revealed that miR-199a-5p, CINC-2, and MCP-1 are candidates for stimulating SHPC growth. Administration of the miR-199a-5p mimic, and not CINC-2, promoted SH growth. SECs treated with CINC-2 induced IL17b expression and their conditioned medium promoted SH growth. Thy1-MC transplantation may accelerate liver regeneration due to SHPCs expansion, which is stimulated by CINC-2/IL17RB signaling and miR-199a-5p.

Transcriptome analysis of hiHepPCs in various culture conditions, human liver-derived hepatocytes, human liver-derived cholangiocytes, HUVECs, and HPBECs

Project description:Transcriptome analysis of human induced hepatic progenitor cells (hiHepPCs) in various culture conditions, human liver-derived hepatocytes, human liver-derived cholangiocytes, human umbilical vein endothelial cells (HUVECs), and human peripheral blood-derived endothelial cells (HPBECs) We found that a specific combination of three transcription factors, FOXA3, HNF1A, and HNF6, could convert HUVECs and HPBECs into cells that closely resembled hepatic progenitor cells in vitro. These hiHepPCs were expandable in long-term culture and able to differentiate into hepatocytes and cholangiocytes in accordance with their culture conditions. We conducted RNA-seq analyses to investigate the characteristincs of hiHepPCs and their progenies, in addition to those of parental HUVECs, HPBECs, and human liver-derived cells.

Comparison of primary vs immortalized murine hepatocytes

Project description:Fundamental research and drug development for personalized medicine necessitates cell cultures from defined genetic backgrounds. However, providing sufficient numbers of authentic cells from individuals poses a challenge. Here, we present a new strategy for rapid cell expansion that overcomes current limitations. Using a small gene library, we expanded primary cells from different tissues, donors and species. Cell type specific regimens that allow the reproducible creation of cell lines were identified. In depth characterization of a series of endothelial and hepatocytic cell lines confirmed phenotypic stability and functionality. Applying this technology enables rapid, efficient and reliable production of unlimited numbers of personalized cells. As such, these cell systems support mechanistic studies, epidemiological research and tailored drug development. In these experiments primary murine hepatocytes were compared to immortalized murine hepatocytes with respect to their global gene expression pattern.

Affymetrix profile of human liver progenitor cells

Project description:Human liver progenitor cells (LPCs) show therapeutic potential, however, their in vitro culture results in inadequate function and phenotypic instability reflecting incomplete understanding of in vivo processes. Foetal LPCs capable of differentiation to a hepatocyte phenotype were isolated and mRNA expression profiling carried out using Affymetrix HGU133plus2 microarrays. This was compared to profiles from mature human hepatocytes and human embryonic stem cells undergoing hepatocytic differentiation. Foetal LPCs exhibit a distinct molecular profile consistent with a stem cell signature, cell division, and some liver-specific functions. 9 independent samples of second trimester liver progenitor cells were profiled along with 3 independent mature hepatocyte samples and 3 each of embryonic stem cells at day 9 and day 17 of differentiation to hepatocyte like cells.
