Abstract

We report here the use of a nanofibrous hydrogel as a 3D scaffold for the culture and maintenance of functional primary human hepatocytes. The system is based on the cooperative assembly of a fiber-forming peptide component, fluorenylmethyloxycarbonyl-diphenylalanine (Fmoc-FF), and the integrin-binding functional peptide ligand, Fmoc-arginine-glycine-aspartic acid (Fmoc-RGD) into a nanofibrous gel at physiological pH. This Fmoc-FF/RGD hydrogel was formulated to provide a biomimetic microenvironment with some critical features such as mechanical properties and nanofiber morphology, which were optimized to support hepatocyte culture. The material was shown to support maintenance and function of encapsulated primary human hepatocytes as indicated by actin staining, qRT-PCR, and functional cytochrome P450 assays. The designed gel was shown to outperform Matrigel in cytochrome P450 functional assays. The hydrogel may prove useful for liver development and disease models, as well as providing insights into the design of future implantable scaffolds for the regeneration of liver tissue in patients with liver disease.

  • Fmoc-FF hydrogels alone failed to maintain hepatocyte viability or function, but addition of integrin-binding RGD dramatically increased cell survival and CYP450 activity, surpassing both 2D cultures and Matrigel for long-term cultures.

    “Self-assembling peptide hydrogels formed from Fmoc-FF alone failed to maintain hepatocyte viability or function, but the addition of integrin-binding motifs such as RGD (Arg-Gly-Asp) dramatically increased cell survival and CYP450 activity, surpassing both 2D cultures and Matrigel for long-term cultures [30].”

    From The Hepatocyte Expansion Paradox: A Review of In Vitro Challenges and Advances (2026) · cites this paper as [30]

    The Results section (page not provided) reports low viability in Fmoc-FF alone and significantly higher survival and CYP450 activity with Fmoc-FF/RGD. It does not support an unqualified claim that the RGD hydrogel surpassed both comparators in long-term cultures: at day 14, CYP450 function exceeded Matrigel but compared well with the 2D control, while survival was comparable to Matrigel.

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.
