Understanding Wound Healing: Exploring Underlying Dynamics, Roles, and Emerging Innovations

Abstract: The skin, constituting the largest organ of the human body, plays a multifaceted role essential for maintaining overall health and homeostasis. A wound can be defined as any injury that disrupts the integrity of the skin or underlying tissues, resulting in damage to the epidermis and potential exposure of deeper structures. Wound healing is a highly specialised, dynamic, multi-phase process that uses a complex mechanism to mend wounded or damaged tissues. A chronic condition is more prone to infections and aberrant scar development, which are the results of any disruption in the complex physiological healing process. Inflammation, tissue creation, and tissue remodelling are the three overlapping stages of wound healing. The role of the TIME principle has also been emphasized in the review, which stresses the importance of Tissue debridement, Inflammation/infection control, Moisture balance, and Edge advancement. Clotting, inflammation, granulation tissue creation, epithelialisation, neovascularisation, collagen synthesis, and wound contraction are the steps of this intricate and ever-changing sequence of events. Despite the advent of numerous therapy regimens, the intricate wound healing mechanism and meticulously long treatment requirements make wounds difficult to diagnose and treat clinically. The review deals with the complex pathways of wound healing, its pathophysiology, and cellular dynamics, along with innovations in skin regeneration and wound healing from scaffolds to biomaterials. The intricate role of flavonoids and antibiotics, along with the advancements in the healing of acute and chronic wounds, has also been discussed. The review also includes the latest strategies like nano-material bacterial fibers, keratin-based formulations, dermis regeneration template (DRT), 3D bioprinting, use of medicalgrade honey (MGH), Steri-Strip orientation, and treatment based on mesenchymal stem cells (MSCs) to manage the complications in healing, which have immense potential to change the wound care paradigm in the future.
