Abstract
Musculoskeletal disorders are a significant burden on the global economy and public health. Hydrogels have significant potential for enhancing the repair of damaged and injured musculoskeletal tissues as cell or drug delivery systems. Hydrogels have unique physicochemical properties which make them promising platforms for controlling cell functions. Gelatin methacryloyl (GelMA) hydrogel in particular has been extensively investigated as a promising biomaterial due to its tuneable and beneficial properties and has been widely used in different biomedical applications. In this review, a detailed overview of GelMA synthesis, hydrogel design and applications in regenerative medicine is provided. After summarising recent progress in hydrogels more broadly, we highlight recent advances of GelMA hydrogels in the emerging fields of musculoskeletal drug delivery, involving therapeutic drugs (e.g., growth factors, antimicrobial molecules, immunomodulatory drugs and cells), delivery approaches (e.g., single-, dual-release system), and material design (e.g., addition of organic or inorganic materials, 3D printing). The review concludes with future perspectives and associated challenges for developing local drug delivery for musculoskeletal applications.

Enhancing esophageal repair with bioactive bilayer mesh containing FGF. Sci Rep 2021; 11:19203. [PMID: 34584186 PMCID: PMC8478899 DOI: 10.1038/s41598-021-98840-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/26/2021] [Accepted: 09/09/2021] [Indexed: 11/08/2022] Open
Abstract
We aimed to prepare a bioactive and biodegradable bilayer mesh formed by fibroblast growth factor (FGF) loaded gelatin film layer, and poly ε-caprolactone (PCL) film layer, and to investigate its treatment efficacy on esophageal anastomosis. It is envisaged that the bioactive mesh in in vivo model would improve tissue healing in rats. The full thickness semicircular defects of 0.5 × 0.5 cm2 were created in anterior walls of abdominal esophagus. The control group had abdominal esophagus isolated with distal esophageal blunt dissection, and sham group had primary anastomosis. In the test groups, the defects were covered with bilayer polymeric meshes containing FGF (5 μg/2 cm2), or not. All rats were sacrificed for histopathology investigation after 7 or 28 days of operation. The groups are coded as FGF(-)-7th day, FGF(+)-7th day, and FGF(+)-28th day, based on their content and operation day. Highest burst pressures were obtained for FGF(+)-7th day, and FGF(+)-28th day groups (p < 0.005) and decreased inflammation grades were observed. Submucosal and muscular collagen deposition scores were markedly increased in these groups compared to sham and FGF(-)-7th day groups having no FGF (p = 0.002, p = 0.001, respectively). It was proved that FGF loaded bioactive bilayer mesh provided effective repair, reinforcement and tissue healing of esophageal defects.

Abstract
Biodegradable polymers have met with an increasing demand in medical usage over the last decades. One of such polymers is poly(ε-caprolactone) (PCL), which is a polyester that has been widely used in tissue engineering field for its availability, relatively inexpensive price and suitability for modification. Its chemical and biological properties, physicochemical state, degradability and mechanical strength can be adjusted, and therefore, it can be used under harsh mechanical, physical and chemical conditions without significant loss of its properties. Degradation time of PCL is quite long, thus it is used mainly in the replacement of hard tissues in the body where healing also takes an extended period of time. It is also used at load-bearing tissues of the body by enhancing its stiffness. However, due to its tailorability, use of PCL is not restricted to one type of tissue and it can be extended to engineering of soft tissues by decreasing its molecular weight and degradation time. This review outlines the basic properties of PCL, its composites, blends and copolymers. We report on various techniques for the production of different forms, and provide examples of medical applications such as tissue engineering and drug delivery systems covering the studies performed in the last decades.

Modified chitosan scaffolds: Proliferative, cytotoxic, apoptotic, and necrotic effects on Saos-2 cells and antimicrobial effect on Escherichia coli. J BIOACT COMPAT POL 2016.

Abstract
Scaffolds used in tissue engineering applications should have high biocompatibility with minimum allergic, toxic, apoptotic, or necrotic effects on the growing cells and newly forming tissue and, if possible, have antimicrobial property to prevent infection at the host site. In this study, novel micro-fibrous chitosan scaffolds, having mineralized bioactive surface to enhance cell adhesion and a model antibiotic (gentamicin) to prevent bacterial attack, were prepared. The effects of the scaffolds on proliferation, viability, apoptosis, and necrosis of Saos-2 cells are reported for the first time. Wet spinning technique was used in the scaffold preparation and biomineralization was achieved by incubating them in five-time concentrated simulated body fluid for 2, 7, or 14 days (coded as CH-BM/2, CH-BM/7, and CH-BM/14, respectively). Gentamicin, an effectively used antibiotic in bone treatments, was loaded by vacuum-pressure cycle. Energy-dispersive X-ray results demonstrated that Ca/P ratio of the mineral phase varies depending on the incubation period. When the scaffolds were cultured with Saos-2 cells, cell adhesion and extracellular matrix formation occurred on all types of scaffolds. Alamar Blue cytotoxicity tests showed correlation among mineral concentration and cytotoxicity where CH-BM/2 had significantly more favorable properties. For all types of scaffolds, apoptosis and necrosis were less than 10%, meaning the samples are biocompatible. Gentamicin-loaded scaffolds showed high antimicrobial efficacy against Escherichia coli. The presence of mineral phase enhanced the adhesive capacity of cells and entrapment efficiency of antibiotic. These results suggest that the bioactive and antimicrobial scaffolds prepared in this study can act as promising matrices in bone tissue engineering applications.

Abstract
A novel elastomeric material, poly(1,8-octanediol-co-citrate) (POC), has demonstrated tremendous versatility because of its advantageous toughness, tunable degradation properties, and efficient drug release capability. In this study, POC was used to improve the mechanical performance of β-tricalcium phosphate (β-Ca3(PO4)2, β-TCP). (3D) β-TCP/POC composite scaffolds were fabricated by a 3D printing technique based on the freeform fabrication system with micro-droplet jetting (FFS-MDJ). The physiochemical properties, compressive modulus, drug release behavior, and cell response of β-TCP/POC composite scaffolds were systematically investigated. The results showed that β-TCP/POC scaffolds had uniform macropores of 300-400 μm, porosity of approximately 45%, biodegradability in phosphate-buffered saline, and high compressive modulus of 50-75 MPa. With the incorporation of POC into β-TCP, the toughness of the composite scaffolds was improved significantly. Moreover, β-TCP/POC scaffolds exhibited sustained drug (ibuprofen (IBU)) release capability. Additionally, β-TCP/POC scaffolds facilitated C2C12 cell attachment and proliferation. It was indicated that the 3D-printed porous β-TCP/POC scaffolds with high compressive modulus and good drug delivery performance might be a promising candidate for bone defect repair.

Abstract
Poly(sebacic anhydride) (PSA) is a promising polymer for the production of drug delivery vehicles. The aim of this work is to study the effect of preparation parameters on the quality of the nanoparticles. In this study, doxorubicin (DOX)-loaded PSA nanocapsules were prepared by an emulsion method. Effects of factors such as type of organic solvent, co-solute (surfactant) and its concentration on drug-loading efficiency, particle size and size distribution, morphology and release profile were examined to gain insight in the preparation and stability of nanostructures. Particles with sizes in the range of 218-1198 nm were prepared. The smallest particles with a narrow size distribution were prepared by using polyvinyl alcohol as a co-solute and dichloromethane as a solvent. Efficiency and intracellular release of doxorubicin from the formulated particles were studied on MDA-MB-231 cells. It was observed that DOX-loaded PSA particles can diffuse into the cells and intracellular antitumour activity is directly related to the released amount of drug from the PSA nanocapsules.

Abstract
Local delivery of therapeutic biomolecules to stimulate bone regeneration has matured considerably during the past decades, but control over the release of these biomolecules still remains a major challenge. To this end, suitable carriers that allow for tunable spatial and temporal delivery of biomolecules need to be developed. Gelatin is one of the most widely used natural polymers for the controlled and sustained delivery of biomolecules because of its biodegradability, biocompatibility, biosafety and cost–effectiveness. The current study reviews the applications of gelatin as carriers in form of bulk hydrogels, microspheres, nanospheres, colloidal gels and composites for the programmed delivery of commonly used biomolecules for applications in bone regeneration with a specific focus on the relationship between carrier properties and delivery characteristics.
