Fabrication of ECM Mimicking Bioactive Scaffold: A Regenerative Approach for MSC Mediated Applications

Abstract

Biomaterials are feasible resources that aids to replace damaged structures in our bodies. The most biologically active flora is Aloe vera which has many bioactive compounds that are anti-inflammatory, antimicrobial, and have ECM mimicking protein content which helps in the healing of wounds and also acts as an ECM factor for stem cell homing and differentiation. The Aloe vera containing 10 $w/v$ of gelatin was lyophilized. Scaffolds had sharper morphology, greater hydrophilic properties, and a Young’s modulus of 6.28 MPa and 15.9 MPa of higher tensile strength are desirable. In tissue engineering and regenerative medicine, biologically active scaffolds have been producing hopeful outcomes in both restoration and replacement, respectively. The objective of the present investigation is to test the idea that incorporating gelatin to Aloe vera scaffolds might enhance their structure, good biocompatibility, and possibly even bioactivity. The SEM picture of the composite scaffold revealed pore walls. The scaffolds had linked pores with diameters ranging from 93 to 296 μm. Aloe vera and the matrix interact well, according to the FTIR study, which could lead to a reduction in the amount of water-binding sites and a reduction in the material’s ability to absorb water. Aloe vera with 10% gelatin (AV/G) scaffold was investigated for different biological reactions of human gingival tissue mesenchymal stem cells (MSCs) in terms of cell proliferation, morphology, and cell migration. The results demonstrated the potential of the AV/G scaffold as a biomaterial that offers new insight in the field of tissue engineering.
