A Model of Mechanotransduction in Polyvinyl Alcohol‐Based Composite Hydrogels for Regulating Musculoskeletal Differentiation (original) (raw)

Macromolecular Materials and Engineering

Abstract

In regenerative medicine, extracellular matrix (ECM)‐inspired materials are currently being explored to imitate mechanotransduction pathways and control cell fate. In musculoskeletal tissue regeneration, enhancing mechano‐biological signals require biomaterials that are both biocompatible and viscoelastic and can retain water content. Herein, based on these requirements, various polyvinyl alcohol (PVA)‐based composite hydrogels, reinforced by polyhydroxy butyrate (PHB) nanofibers, are proposed to differentiate equine adipose‐derived stem cells for musculoskeletal regeneration. To study the role of fiber embedding in improving scaffold properties, different nanofiber assemblies, including chopped short ones with random orientation (PVAS), single‐layer (PVAL1), and double‐layer membranes (PVAL2) are positioned into the PVA matrix. PHB reinforcements negatively affect swelling and positively enhanced phase transition temperatures and crystallinity of PVA hydrogel. According to mechanic...
