Human stem cell-derived hepatocyte-like cells support Zika virus replication and provide a relevant model to assess the efficacy of potential antivirals.

ABSTRACT: Zika virus (ZIKV) infection during pregnancy has been extensively linked to microcephaly in newborns. High levels of ZIKV RNA were, however, also detected in mice and non-human primates in organs other than the brain, such as the liver. As ZIKV is a flavivirus closely related to the dengue and yellow fever virus, which are known to cause hepatitis, we here examined whether human hepatocytes are susceptible to ZIKV infection. We demonstrated that both human pluripotent stem cell (hPSC)-derived hepatocyte-like cells (HLCs) and the Huh7 hepatoma cell line support the complete ZIKV replication cycle. Of three antiviral molecules that inhibit ZIKV infection in Vero cells, only 7-deaza-2'-C-methyladenosine (7DMA) inhibited ZIKV replication in hPSC-HLCs, while all drugs inhibited ZIKV infection in Huh7 cells. ZIKV-infected hPSC-HLCs but not Huh7 cells mounted an innate immune and NF?? response, which may explain the more extensive cytopathic effect observed in Huh7 cells. In conclusion, ZIKV productively infects human hepatocytes in vitro. However, significant differences in the innate immune response against ZIKV and antiviral drug sensitivity were observed when comparing hPSC-HLCs and hepatoma cells, highlighting the need to assess ZIKV infection as well as antiviral activity not only in hepatoma cells, but also in more physiologically relevant systems.

Project description:BACKGROUND & AIMS:Hepatocyte-like cells (HLCs) differentiated from induced pluripotent stem cells (iPSCs) have emerged as a promising cell culture model to study metabolism, biotransformation, viral infections and inherited liver diseases. iPSCs provide an unlimited supply for the generation of HLCs, but incomplete HLC differentiation remains a major challenge. iPSC may carry-on a tissue of origin dependent expression memory influencing iPSC differentiation into different cell types. Whether liver derived iPSCs (Li-iPSCs) would allow the generation of more fully differentiated HLCs is not known. METHODS:In the current study, we used primary liver cells (PLCs) expanded from liver needle biopsies and reprogrammed them into Li-iPSCs using a non-integrative Sendai virus-based system. Li-iPSCs were differentiated into HLCs using established differentiation protocols. The HLC phenotype was characterized at the protein, functional and transcriptional level. RNA sequencing data were generated from the originating liver biopsies, the Li-iPSCs, fibroblast derived iPSCs, and differentiated HLCs, and used to characterize and compare their transcriptome profiles. RESULTS:Li-iPSCs indeed retain a liver specific transcriptional footprint. Li-iPSCs can be propagated to provide an unlimited supply of cells for differentiation into Li-HLCs. Similar to HLCs derived from fibroblasts, Li-HLCs could not be fully differentiated into hepatocytes. Relative to the originating liver, Li-HLCs showed lower expression of liver specific transcription factors and increased expression of genes involved in the differentiation of other tissues. CONCLUSIONS:PLCs and Li-iPSCs obtained from small pieces of human needle liver biopsies constitute a novel unlimited source for the production of HLCs. Despite the preservation of a liver specific gene expression footprint in Li-iPSCs, the generation of fully differentiated hepatocytes cannot be achieved with the current differentiation protocols.
