Creating acellular vascularized constructs from animal and plant tissue is one of the well-known strategies for scaffold assembly. Decellularization takes an important position among these strategies. The most common method is chemical decellularization. This approach employs high concentrations of detergents, primarily Triton X-100, sodium dodecyl sulfate (SDS), and sodium hypochlorite (SH). In this work, novel techniques for decellularizing spinach were developed using detergents frequently utilized in laboratories. Spinach leaves were decellularized using Tween-20, SDS, and SH at low concentrations to generate an acellular plant matrix for tissue engineering. We measured the quantities of DNA and protein, as well as the decellularization using hematoxylin and eosin (H&E) staining. The biocompatibility and capacity of the biostructures to stimulate fibroblast wound healing were assessed using MTT and the Scratch assay. The antibacterial activity of the scaffolds was also tested against a gram-positive bacterium, Staphilococcus aureus, which is a common pathogen associated with wound healing. The best shape, evident vascularization, and good biocompatibility were seen in the Tween-20 decellularized samples at 1% concentration at 21°C and 37°C through the enhancement of cell proliferation and wound healing. In terms of antibacterial activity, all scaffold samples had a significant effect on Staphilococcus aureus, where the number of bacterial colonies in all six scaffold groups became zero after 4 h of treatment. The scaffolds also showed a 100% kill rate on Staphilococcus aureus, which could avoid wound infection during the repair process, and that can be suggested as a scaffold for tissue engineering applications and an important constituent for pharmacological activities.
