Synergistic integration of ADSCs and egg white hydrogel microspheres for accelerated wound regeneration

Abstract

Accelerating wound healing poses a significant challenge in clinical practice, necessitating the exploration of innovative strategies. The development of biomaterials with tissue repair and regenerative properties represents a forefront approach to addressing this challenge; however, the functional characteristics and application methods of these materials remain limited. In this context, a novel bioactive micro carrier (Bio-MC) was developed from egg white hydrogel microspheres (EWMs) which served as a bio-niche incorporating adipose-derived stem cells (ADSCs). This formulation capitalizes on the intrinsic tissue reparative capabilities of stem cells, allowing for the sustained release of multiple growth factors. These factors, via paracrine signaling, promote the proliferation and migration of neighboring cells, thereby creating an environment that supports wound healing. Upon application to wound sites, Bio-MCs exhibited significant effectiveness in enhancing the healing process by promoting tissue regeneration, increasing collagen deposition, and facilitating vascularization. The paracrine signaling mediated by Bio-MCs has the potential to exert lasting beneficial effects on cells in a comprehensive and physiologically relevant manner. In comparison to conventional growth factor treatments, the Bio-MC offers enhanced application versatility and functional attributes, indicating substantial promise in the field of tissue repair and regeneration and representing a noteworthy advancement in the clinical management of wounds.
