The road to regenerative liver therapies: the triumphs, trials and tribulations
Open accessAbstract
The liver is one of the few organs that possess a high capacity to regenerate after liver failure or liver damage. The parenchymal cells of the liver, hepatocytes, contribute to the majority of the regeneration process. Thus, hepatocyte transplantation presents an alternative method to treating liver damage. However, shortage of hepatocytes and difficulties in maintaining primary hepatocytes still remain key obstacles that researchers must overcome before hepatocyte transplantation can be used in clinical practice. The unique properties of pluripotent stem cells (PSCs) and induced pluripotent stem cells (iPSCs) have provided an alternative approach to generating enough functional hepatocytes for cellular therapy. In this review, we will present a brief overview on the current state of hepatocyte differentiation from PSCs and iPSCs. Studies of liver regenerative processes using different cell sources (adult liver stem cells, hepatoblasts, hepatic progenitor cells, etc.) will be described in detail as well as how this knowledge can be applied towards optimizing culture conditions for the maintenance and differentiation of these cells towards hepatocytes. As the outlook of stem cell-derived therapy begins to look more plausible, researchers will need to address the challenges we must overcome in order to translate stem cell research to clinical applications.

It is difficult to propagate or even maintain hepatocytes in a functional differentiated state in vitro.
“It is notoriously difficult to propagate or even maintain hepatocytes in a functional differentiated state in vitro.”
From Hippo Signaling Influences HNF4A and FOXA2 Enhancer Switching during Hepatocyte Differentiation (2014) · cites this paper as Raju et al., 2013
Investigators have achieved partial success in propagating/maintaining hepatocytes in vitro by developing 3D tissue culture models and using a multitude of extracellular matrix components in the form of Matrigel.
“Investigators have achieved partial success by developing 3D tissue culture models and using a multitude of extracellular matrix (ECM) components in the form of Matrigel (Raju et al., 2013).”
From Hippo Signaling Influences HNF4A and FOXA2 Enhancer Switching during Hepatocyte Differentiation (2014) · cites this paper as Raju et al., 2013
The Introduction describes difficulty maintaining primary hepatocytes in culture, and its Adult liver stem cells section describes a decellularized liver biomatrix used for differentiation. Searches for Matrigel and 3D tissue culture models found no passage saying those approaches achieved the claimed partial success. (LLM, conf=0.72)

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
