Overview

Computational modeling demonstrates optimized RGD peptides support stem cell adhesion and self-renewal without ROCK inhibitors, indicating scalable pathways for clinical stem cell culture.

Key Points

To design and computationally evaluate optimized RGD-flanking peptide sequences that enhance integrin binding, adhesion, and self-renewal in human pluripotent stem cell cultures.
Generated three-dimensional structural models of integrin αVβ5 using AlphaFold and modeled peptide-integrin interactions via molecular docking with αVβ3 and αVβ5.
Performed molecular dynamics simulations to evaluate the stability of peptide-integrin complexes and analyze RGD-flanking sequence patterns.
Evaluated candidate peptide-displaying surfaces for their capacity to support hPSC adhesion and long-term self-renewal without ROCK inhibitors.
Molecular dynamics simulations established specific RGD-flanking sequence patterns that govern complex stability with αVβ3 and αVβ5 integrins.
Identified computationally optimized peptides capable of sustaining long-term hPSC self-renewal and adhesion under feeder-free conditions lacking ROCK inhibitors.
