Xiao W, Zhang J, Qu X, Chen K, Gao H, He J, Ma T, Li B, Liao X. Fabrication of protease XIV-loaded microspheres for cell spreading in silk fibroin hydrogels. JOURNAL OF MATERIALS SCIENCE. MATERIALS IN MEDICINE 2020; 31:128. [PMID: 33247786 DOI: 10.1007/s10856-020-06466-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/16/2020] [Revised: 05/12/2020] [Accepted: 11/03/2020] [Indexed: 06/12/2023]
Abstract
Due to their excellent mechanical strength and biocompatibility, silk fibroin(SF) hydrogels can serve as ideal scaffolds. However, their slow rate of natural degradation limits the space available for cell proliferation, which hinders their application. In this study, litchi-like calcium carbonate@hydroxyapatite (CaCO3@HA) porous microspheres loaded with proteases from Streptomyces griseus (XIV) were used as drug carriers to regulate the biodegradation rate of SF hydrogels. The results showed that litchi-like CaCO3@HA microspheres with different phase compositions could be prepared by changing the hydrothermal reaction time. The CaCO3@HA microspheres controlled the release of Ca ions, which was beneficial for the osteogenic differentiation of mesenchymal stem cells (MSCs). The adsorption and release of protease XIV from the CaCO3@HA microcarriers indicated that the loading and release amount can be controlled with the initial drug concentration. The weight loss test and SEM observation showed that the degradation of the fibroin hydrogel could be controlled by altering the amount of protease XIV-loaded CaCO3@HA microspheres. A three-dimensional (3D) cell encapsulation experiment proved that incorporation of the SF hydrogel with protease XIV-loaded microspheres promoted cell dispersal and spreading, suggesting that the controlled release of protease XIV can regulate hydrogel degradation. SF hydrogels incorporated with protease XIV-loaded microspheres are suitable for cell growth and proliferation and are expected to serve as excellent bone tissue engineering scaffolds.

Abstract
Poly(vinyl alcohol) (PVA) hydrogels have been considered as promising implants for various soft tissue engineering applications because of their tissue-like viscoelasticity and biocompatibility. However, two critical barriers including lack of sufficient mechanical properties and non-tissue-adhesive characterization limit their application as tissue substitutes. Herein, PVA is methacrylated with ultralow degrees of substitution of methacryloyl groups to produce PVA-glycidyl methacrylate (GMA). Subsequently, the PVA-GMA/methacrylate-functionalized silica nanoparticle (MSi)-based nanocomposite hydrogels are developed via the photopolymerization approach. Interestingly, both PVA-GMA-based hydrogels and PVA-GMA/MSi-based nanocomposite hydrogels exhibit outstanding compressive properties, which cannot be damaged through compressive stress-strain tests in the allowable scope of a tensile tester. Moreover, PVA-GMA/MSi-based nanocomposite hydrogels demonstrate excellent tensile properties compared with neat PVA-GMA-based hydrogels, and 15-, 14-, and 24-fold increase in fracture stress, elastic modulus, and toughness, respectively, is achieved for the PVA-GMA/MSi-based hydrogels with 10 wt % of MSi. These remarkable enhancements can be ascribed to the amount of long and flexible polymer chains of PVA-GMA and the strong interactions between the MSi and PVA-GMA chains. More interestingly, exciting improvements in the cell adhesion can also be successfully achieved by the incorporation of MSi nanoparticles.

Abstract
Stem cells have emerged as potentially useful cells for regenerative medicine applications. To fully harness this potential, it is important to develop in vitro cell culture platforms with spatially regulated mechanical, chemical, and biological cues to induce the differentiation of stem cells. In this study, a cell culture platform was constructed that used polydopamine (PDA)-coated parafilm. The modified parafilm supports cell attachment and proliferation. In addition, because of the superb plasticity and ductility of the parafilm, it can be easily micropatterned to regulate the spatial arrangements of cells, and can exert different mechanical tensions. Specifically, we constructed a PDA-coated parafilm with grooved micropatterns to induce the osteogenic differentiation of stem cells. Adipose-derived mesenchymal stem cells that were cultured on the PDA-coated parafilm exhibited significantly higher osteogenic commitment in response to mechanical and spatial cues compared to the ones without stretch. Our findings may open new opportunities for inducing osteogenesis of stem cells in vitro using the platform that combines mechanical and spatial cues.

Abstract
Physically crosslinked poly(vinyl alcohol) (PVA) hydrogels prepared using a low-temperature thermally cycled process have tunable mechanical properties that fall within the range of soft tissues, including cardiovascular tissue. An approach to render it hemocompatible is by endothelization, but its hydrophilic nature is not conducive to cell adhesion and spreading. We investigated the functionalization reaction of this class of PVA hydrogel with fibronectin (FN) for adhesion and spreading of primary porcine radial artery cells and vascular endothelial cells. These are cells relevant to small-diameter vascular graft development. FN functionalization was achieved using a multistep reaction, but the activation step involving carbonyl diimidazole normally required for chemically crosslinked PVA was found to be unnecessary. The reaction resulted in an increase in the elastic modulus of the PVA hydrogel but is still well within the range of cardiovascular tissue. Confocal microscopy confirmed the adhesion and spreading of both cell types on the PVA-FN surfaces, whereas cells failed to adhere to the PVA control. This is a first step toward an alternative for the realization of a synthetic replacement small-diameter vascular graft.

Abstract
The objective of this study was to synthesize and characterize novel three-dimensional porous scaffolds made of poly(lactic-co-glycolic acid) (PLGA)/nano-TiO(2)-particle composite microspheres for potential bone repair applications. The introduction of TiO(2) component has been proven capable of largely enhancing mechanical properties of PLGA/TiO(2) microsphere-sintered scaffold ("PLGA/TiO(2)-SMS"). In addition, composite nano-TiO(2) additives are capable of inducing an increased arrest of adhesive proteins from the environment, which benefits cell attachment onto the scaffolds. Osteoblast proliferation and maturation were evaluated by MTT assay, alkaline phosphatase (ALP) activity, and bony calcification assay. The results indicate that osteoblasts cultured on the composite scaffolds with different TiO(2) content (0, 0.1, and 0.3 g/1 g PLGA) display increased cell proliferation compared with pure PLGA scaffold. When cultured on composite scaffolds, osteoblasts also exhibit significantly enhanced ALP activity and higher calcium secretion, with respect to those on the pure PLGA scaffolds. Taken together, PLGA/TiO(2)-SMSs deserve attention utilizing for potential bone-repairing therapeutics.

Abstract
The current practice of cell immunotherapy against cancer has encountered a substantial challenge, that is, targeted delivery of therapeutic cells to tumour sites is not favourably managed. In this study, we aimed to provide an engineering solution to govern the cell targeting and actions, for which a biomaterial model is developed to mediate the conveyance and accommodation of activated immunocytes with anti-cancer potentials. We fabricated a dual-layered hydrogel/microsphere (GS) composite, which preserves all advantageous features of hydrogel such as injectability and favourable permeability, to achieve genuine localisation and physical immobilisation of the executing immunocytes-macrophages. According to our presented in vitro investigations, the GS immunoconstruct exhibited effective elimination of carcinoma cells as well as high safety free of gene alteration or cell leakage. Notably, unwanted long-term proliferation of the delivered cells was restrained by physical encapsulation in the bio-inert 3D hydrogel frameworks. By these efforts, we have provided an immunocyte delivery platform with which cell-based immunotherapy can be initiated at a desired location and implemented in a controlled manner.

Abstract
This study developed a transplantable platform based on cationic hydrogels to deliver antisense oligodeoxynucleotides (ASOs) targeting the mRNA of TNF-alpha. Cationic agarose (c-agarose) was obtained by conjugating ethylenediamine to agarose via an N,N'-carbonyldiimidazole (CDI)-activation method. ASO-c-agarose system was constructed by mixing ASO in cationic agarose gel of proper concentration and gelation temperature. In vivo assessment of ASO distribution suggested that the system specifically target to spleen, wherein the c-agarose-delivered ASO had a concentration remarkably 50-fold higher than that of the naked ASO. The distribution of c-agarose-delivered ASO was scarcely detectable in liver and kidney. Next, three types of animal models were setup to evaluate the therapeutic efficacies of ASO-Gel, including the adjuvant-induced arthritis (AA), carrageen/lipopolysaccharide (LPS)-induced arthritis (CLA) and collagen-induced arthritis (CIA) models. The effects of ASO-c-agarose in alleviating inflammation and tissue destruction were evidenced in more than 90% of the testing animals, with decrease of main inflammatory cytokines, lightening of joint swelling and tissue damage, as well as increase in their body weights. All these findings suggest that this highly operable devise for the conveyance of antisense nucleotides together with its spleen-targeting property, could become a useful means of antisense-based therapeutics against rheumatoid arthritis and other diseases.
