Methodologies of Autologous Skin Cell Spray Graft.

Abstract

Healthcare workers continue to struggle with skin wound management. Despite the fact that there have been many methods created throughout the decades for skin regeneration, contemporary developments in regenerative medicine provide highly reliable methods for creating synthetic skin replacements, such as electrospinning, 3D bioprinting, or spraying, among all others. Specifically, skin sprays have been a cutting-edge method that is currently undergoing clinical testing and has lots of promise for providing cells and hydrogels to cure both acute and chronic wounds. Deposition of cells and scaffolding materials in successive layers over the burnt regions characterises 3D bioprinting for burn injury repair. Depending on the desired outcome, bioprinting of skin may be performed in vivo or in vitro. However, the location of the printing and the time required for the tissue to mature separates these two methods. Bioprinted skin for use in burn repair faces technical and regulatory hurdles before it may be used in clinical settings. Skin sprays provide various benefits to traditional wound care methods, inclusive of ease of administration, the ability to treat broad wound regions, and a consistent dispersion of the sprayed substance. The most recent developments in this technology are reviewed in this article, along with a thorough explanation of investigational and presently marketed acellular and cellular skin spray solutions that are utilized to treat a range of illnesses and administer various experimental materials. Additionally, we describe regulatory processes for their capitalization and cover key clinical studies for various skin illnesses and associated treatment circumstances because skin spray products are susceptible to several classifications. Finally, we provide an argument and offer potential future developments in the biotechnology of skin sprays for improved clinical dermatological applications.
