Project description:The differentiation of pluripotent stem cells to hepatocyte-like cells offers the perspective of unlimited supply of human hepatocytes. However, the degree of differentiation of hepatic-like cells (HLC) remains controversial. To obtain an unbiased characterization, we performed a transcriptomics study using the Affymetrix Gene Chip® HG-U133 plus 2.0, with HLC derived from embryonic and induced stem cells (ESC, hiPSC) from two different laboratories. Genome-wide gene expression profiles of ESC and HLC were compared to freshly isolated and up to 14 days cultivated primary human hepatocytes (see submission E-MTAB-3994) obtained under patient informed consent from three male donors. Three biological replicas were used for each ESC and HLC models.

Project description:Robust and scalable differentiation of human pluripotent stem cells into high-quality hepatocyte-like cells (HLC) is achieved by acting on Wnt/b-catenin and TGFb pathways and taking advantage of latest knowledge on human liver development. Obtained HLC are comparable to primary human hepatocytes and superior to stem cell-derived hepatocytes generated with previously described protocols. As a proof of concept, such HLC were used to assess drug hepatotoxicity and study human ductal plate and bile duct morphogenesis in a complex liver organoid model.

Project description:Recent advances towards the efficient and reproducible differentiation of stem cells into hepatocyte-like cells (HLC) have created potential opportunities in clinical transplantation. For this approach to be successfully translated, however, it is necessary to understand the immune response to stem cell-derived cellular products. Whereas both embryonic stem cells and induced pluripotent stem cells have been utilized as cellular sources for differentiation and lineage specification, their relative ability to be recognized by immune effector cells is unclear. Here we determine the expression of immune recognition molecules on HLC generated from murine embryonic stem cells and induced pluripotent stem cells, compared to adult hepatocytes, and we evaluate the impact on recognition by NK cells. We report that HLC lack MHC class I expression, and that embryonic stem cell derived-HLC have higher expression of the NK cell activating ligands Rae1, H60, and Mult1 than induced pluripotent stem cell-derived HLC and adult hepatocytes. Moreover, the lack of MHC class I render embryonic stem cell derived-HLC, and induced pluripotent stem cell derived-HLC, susceptible to killing by syngeneic and allogeneic NK cells. Both embryonic stem cell derived-HLC, and induced pluripotent stem cell derived-HLC, are killed by NK cells at higher levels than adult hepatocytes. Finally, we demonstrate that the NK cell activation receptor, NKG2D, plays a key role in NK cell killing of embryonic stem cell derived-HLC, but not induced pluripotent stem cell-derived HLC. Hepatocytes were isolated from FVB/NJ mice and C57Bl/6 mice using a modification of the Seglen’s perfusion technique.

Project description:Human pluripotent stem cells (hPSCs) can differentiate into all cell types in the body that may replace current cell sources applied in regenerative medicine, cell therapy, drug discovery and development and general research. Human PSC-derived hepatocyte-like cells (HLCs) have the potential to replace primary hepatocytes and other cell models applied in liver disease treatment and drug discovery and development. These cells share many features with their in vivo counterparts however, the generation of fully functional hPSC-derive HLCs is still lacking, which prevent their application in the previously mentioned fields. This study followed the transcriptome dynamics during the differentiation of hPSC-derived HLCs at definitive endoderm, hepatoblast, early HLC and late HLC developmental stages and the controls hPSCs and human liver tissues which consists of at least 70% hepatocytes. The aim is to reveal expression deviations between hPSC-derived hepatocytes and their in vivo counterparts that may contribute to the modification of differentiation protocols to generate fully functional hepatocytes.

Project description:During embryonic development bipotential hepatoblasts differentiate into hepatocytes and cholangiocytes- the two main cell types within the liver. Cell fate decision depends on elaborate interactions between distinct signalling pathways, namely Notch, WNT, TGFβ, and Hedgehog. Several in vitro protocols have been established to differentiate human pluripotent stem cells into either hepatocyte or cholangiocyte like cells (HLC/CLC) to enable disease modelling or drug screening. During HLC differentiation we observed the occurrence of epithelial cells with a phenotype divergent from the typical hepatic polygonal shape- we refer to these as endoderm derived epithelial cells (EDECs). These cells do not express the mature hepatocyte marker ALB or the progenitor marker AFP. However they express the cholangiocyte markers SOX9, OPN, CFTR as well as HNF4α, CK18 and CK19. Interestingly, they express both E Cadherin and Vimentin, two markers that are mutually exclusive, except for cancer cells. EDECs grow spontaneously under low density cell culture conditions and their occurrence was unaffected by interfering with the above mentioned signalling pathways.

Project description:SVF was isolated from ABD and GF-adipose tissue biopsies by collagenase digestion and centrifugation, from 5 healthy women (38yo ±4.4; 31.8kg/m-2 ±3.12; WHR 0.86 ±0.05). After isolation, cells were counted with a Countess II automated cell counter (Thermofisher Scientific). Single cell suspension (56K/mL) was distributed into eight wells of a 384-well source plate (Takara Bio USA, San Jose, CA) and dispensed onto a iCELL8 350v Chip (Takara Bio USA) using an iCELL8 MultiSample NanoDispenser (Takara Bio USA). We distributed the ABD and GF-SVF of each subject on the same chip. The method used was described in [6]. In brief, mRNA from single cells were isolated, converted to full-length cDNA prior to unbiased amplification of 3’ and 5’ ends using SMART-Seq® ICELL8® Application Kit (Takara Bio, USA). Multiplexed sequencing libraries were generated from cDNA using the Illumina Nextera XT protocol and 150bp paired-end sequencing was performed on an Novogene HiSeqX instrument.
