The intricate process of wound healing, characterized by a dynamic series of events, finds its proper advancement dictated by paracrine factors' precise modulation during each phase of healing. amphiphilic biomaterials The inappropriate progression through the different stages of wound healing is connected with inadequate epidermal regeneration (i.e., re-epithelialization) and the development of persistent wounds such as diabetic ulcers, causing a rise in patient morbidity. The dynamic secretome of Adipose-derived Mesenchymal Stem Cells (ASCs) has been investigated recently, with findings indicating potential benefits for wound healing in cases of chronic diabetes. While 2D culture techniques are currently utilized, they are widely understood to dramatically impact the regenerative phenotype of ASCs. In this study, a novel 3D tissue-mimetic system was utilized to culture autologous stem cells (ASCs).
To determine the potential of the ASC secretome to improve epidermal regeneration, ASCs were subjected to wound-priming stimuli in both two-dimensional and three-dimensional models, after which the assessment was conducted. The 2D and 3D systems received priming stimuli in the form of a coating with collagen type I, fibronectin, and fibrin wound matrix proteins. To ascertain the potential advantages of the ASC secretome for diabetic wounds, keratinocytes (KCs) were subjected to super-physiological glucose concentrations to induce a diabetic-like cellular state (idKCs).
A 52% reduction in proliferation and a 23% decrease in migration were observed in idKC compared to KCs. After these steps, analyses were performed to ascertain the components secreted by the ASC. Tissue-mimetic cultures of ASCs generated ASC-conditioned media (ASC-CM) displaying over a 50% rise in protein secretion and a twofold upsurge in secreted EVs, when contrasted with those grown in a 2D environment. Importantly, the different priming stimuli did not alter the total amount of proteins and EVs that were secreted within the tissue-like model. Further investigation into soluble proteins, employing the ELISA method, highlighted significant variations in key epidermal regeneration factors, such as EGF, IGF-1, FGF-2, MMP-1, TIMP-1, and TGF.
