Abstract
Chronic wounds significantly contribute to disability and affect the mortality rate in diabetic patients. In addition, pressure ulcers, diabetic foot ulcers, arterial ulcers, and venous ulcers pose a significant health burden due to their associated morbidity and death. The complex healing process, environmental factors, and genetic factors have been identified as the rate-limiting stages of chronic wound healing. Changes in temperature, moisture content, mechanical strain, and genetics can result in slow wound healing, increased susceptibility to bacterial infections, and poor matrix remodelling. These obstacles can be addressed with natural biomaterials exhibiting antimicrobial, collagen synthesis, and granulation tissue formation properties. Recently, silk proteins have gained significant attention as a natural biomaterial owing to good biocompatibility, biodegradability, reduced immunogenicity, ease of sterilization, and promote the wound healing process. The silk components such as sericin and fibroin in combination with nano(platforms) effectively promote wound repair. This review emphasises the potential of sericin and fibroin when combined with nano(platforms) like nanoparticles, nanofibers, and nanoparticles-embedded films, membranes, gels, and nanofibers.

Lee WJ, Cho K, Lee D, Lee S, Jeon H, Kim AY, Kim GW. Enhanced osteogenic potential of spider silk fibroin-based composite scaffolds incorporating carboxymethyl cellulose for bone tissue engineering. BIOMATERIALS AND BIOSYSTEMS 2024; 16:100103. [PMID: 39654876 PMCID: PMC11625154 DOI: 10.1016/j.bbiosy.2024.100103] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2024] [Revised: 11/17/2024] [Accepted: 11/18/2024] [Indexed: 12/12/2024] Open
Abstract
This study aimed to investigate the characteristics of composite scaffolds that combine fibroin derived from spider silk and carboxymethyl cellulose (CMC) in the field of bone tissue engineering. Fibroin, obtained from spider silk, serves as a valuable biomaterial and constitutes the primary component of fibrous protein-based spider silk threads. To enhance the binding efficiency in bone formation after scaffold implantation, CMC was integrated into fibroin, aiming to improve the injectability properties of the scaffold in bone substitutes. For bone marrow mesenchymal stem cell (BMSC) tissue engineering, BMSCs isolated from mice were seeded onto the scaffold, and the rate of cell proliferation was assessed. The composite scaffold, with the addition of CMC to fibroin, exhibited superior characteristics compared to scaffolds containing only silks, including porous morphology, porosity, surface wettability, water absorption, and thermal properties. Alkaline phosphatase activity in BMSCs was significantly higher in the CMC-containing scaffold compared to the silk-only scaffold, and the CMC-containing scaffold demonstrated increased expression of osteocyte marker genes and proteins. In conclusion, the biocompatibility and hydrophilicity of CMC-containing scaffolds play essential roles in the growth and proliferation of osteocytes. Furthermore, the CMC-containing scaffold design proposed in this study is expected to have a substantial impact on promoting ossification of BMSCs.

Abstract
Silk fibroin (SF) is a natural protein (biopolymer) extracted from the cocoons of Bombyx mori L. (silkworm). It has many properties of interest in the field of biotechnology, the most important being biodegradability, biocompatibility and robust mechanical strength with high tensile strength. SF is usually dissolved in water-based solvents and can be easily reconstructed into a variety of material formats, including films, mats, hydrogels, and sponges, by various fabrication techniques (spin coating, electrospinning, freeze-drying, and physical or chemical crosslinking). Furthermore, SF is a feasible material used in many biomedical applications, including tissue engineering (3D scaffolds, wounds dressing), cancer therapy (mimicking the tumor microenvironment), controlled drug delivery (SF-based complexes), and bone, eye and skin regeneration. In this review, we describe the structure, composition, general properties, and structure-properties relationship of SF. In addition, the main methods used for ecological extraction and processing of SF that make it a green material are discussed. Lastly, technological advances in the use of SF-based materials are addressed, especially in healthcare applications such as tissue engineering and cancer therapeutics.
