Abstract
Wound healing is a dynamic interactive process involving soluble mediators blood cells and ECM Extra Cellular Matrix Significant changes in ECM degradation may lead to delayed wound healing Matrix metalloproteinase MMPs are a family of endopeptidases that function in the remodeling of ECM proteins wherein overexpression of these MMPs is capable of degrading ECM and biologically active proteins at the wound sites Regulations of these MMPs at the wound sites hasten the wound healing The aim of this study is to release the product which inhibits MMPs and as well as to reduce the bacterial load on the wound site in a controlled manner Siderophore organic ion chelator was isolated from Pseudomonas aeruginosa strain S1 and purified through various chromatographic techniques used as for dual purpose in this study The design and development of wound dressing through a carrier system such as microspheres are indeed a novel approach to promote healing The design in this study includes preparation of microspheres using gelatin and siderophore SGM The morphological characteristics of the prepared microspheres were found to be rigid highly porous and their mean diameter of five siderophoreloaded microspheres formulations was between 70 ± 052 and 253 ± 0 31 µm The drug release of the prepared samples was fast and entrapment efficiency was about 93 at 24 h in Batch 3 Gelatinmodified microspheres were found to be nontoxic and a good biocompatible product which was assessed using NIH 3T3 fibroblast cell lines The overall study suggests that SGM microspheres could be used as a potent tool for MMP inhibitor for wound healing applicationsThe author gratefully acknowledges financial support for this work through the grants awarded by the Department of Science and Technology DST New Delhi India SR/WOSA/LS375 Financial support from CSIR under Translational Project OLP09/TRP is acknowledged
