Towards Induction of Angiogenesis in Dental Pulp Stem Cells Using Chitosan-Based Hydrogels Releasing Basic Fibroblast Growth Factor. BIOMED RESEARCH INTERNATIONAL 2022; 2022:5401461. [PMID: 35198635 PMCID: PMC8860569 DOI: 10.1155/2022/5401461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/05/2021] [Revised: 11/26/2021] [Accepted: 01/19/2022] [Indexed: 11/17/2022]
Abstract
Introduction. Chitosan is a natural biopolymer that attracted enormous attention in biomedical fields. The main components of regenerative endodontic procedures (REPs), as well as tissue engineering, are scaffolds, stem cells, and growth factors. As one of the basic factors in the REPs is maintaining vascularization, this study was aimed at developing basic fibroblast growth factor- (bFGF-) loaded scaffolds and investigating their effects on the angiogenic induction in human dental pulp stem cells (hDPSCs). Methods. Poly (ε-caprolactone) (PCL)/chitosan- (CS-) based highly porous scaffold (PCL/CS) was prepared and evaluated by scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR) analyses. The adhesion and survival potency of seeded cells were assessed by SEM and MTT assays, respectively. The amount of angiogenic markers was investigated in gene and protein levels by real-time PCR and western blotting assays, respectively. Results. Based on our findings, the SEM and FTIR tests confirmed the appropriate structure of synthesized scaffolds. Besides, the adhesion and survival rate of cells and the levels of VEGFR-2, Tie2, and Angiopoietin-1 genes were increased significantly in the PCL/CS/bFGF group. Also, the western blotting results showed the upregulation of these markers at protein levels, which were considerably higher at the PCL/CS/bFGF group (
). Conclusions. On a more general note, this study demonstrates that the bFGF-loaded PCL/CS scaffolds have the potential to promote angiogenesis of hDPSCs, which could provide vitality of dentin-pulp complex as the initial required factor for regenerative endodontic procedures.

Abstract
Tissue engineering is concerned about the rejuvenation and restoration of diseased and damages tissues/organs using man-made scaffolds that mimic the native environment of the cells. In recent years, a variety of biocompatible and biodegradable natural materials is employed for the fabrication of such scaffolds. Of these natural materials, chitosan is the most preferred one as it imitates the extracellular matrix (ECM) of the cells. Moreover, chitosan-based materials are pro-angiogenic and have antibacterial activity. These materials can be easily fabricated into the desired shape of the scaffolds that are suitable for tissue support and regeneration. Growth factors are small proteins/peptides that support and enhance the growth and differentiation of cells into a specific lineage. It has been observed that scaffolds capable of delivering growth factor promote tissue repair and regeneration at a faster rate when compared to scaffolds without growth factor. The present review focuses on the recent developments on chitosan-based scaffolds for the delivery of growth factors thereby improving and enhancing tissue regeneration.

Abstract
Bovine rumen is hitherto considered as an inedible waste of meat industry. The rumen tissues can be used as an alternative source of collagen to produce biocompatible materials for clinical application. In an effort to develop a functional biomaterial from the inedible mammalian tissues, this study aims to isolate and characterize bovine rumen submucosa. Initially, the rumen tissue was sequentially processed using chemical and enzymatic treatment to decellularize, neutralize, stabilize, and to produce a native collagen matrix which is referred as collagen film (COL-F). Thus, prepared matrix was treated with 1% (w/v) chitosan solution to produce a hybrid film which is referred as collagen–chitosan film (COL/CS-F). The comparative study includes the evaluation of physical, chemical, and biological properties of the biofilms prepared. The surface topology of COL-F exhibited a continuous collagenous network with fibrous nature, while the chitosan treatment provided smooth plain surface to the parent film. Incorporation of chitosan in COL-F increased the tensile properties, as well as the thermal stability and durability of the films. The Fourier Transform Infrared spectroscopy results revealed the presence of respective amide peaks, which corresponds to protein (collagen), and the evidence of collagen–chitosan interlinking. The submucosa layer was electrophoretically found to have type I collagen. The X-ray diffraction data showed the presence of amorphous and crystalline peak which attributes to the triple helical structure of collagen in the films. Cytotoxicity studies on the films were performed in vitro using human keratinocytes. The results of cell viability and proliferation demonstrated that COL-F and COL/CS-F exhibit good biocompatibility and therefore can augment cell infiltration and proliferation. However, enhanced cellular activity was observed on the chitosan treated COL-F. These observations demonstrate that the biofilms prepared in this study can be used as an alternative functional biomaterial in tissue engineering.

Abstract
Controlled and local release of bioactive growth factors from porous scaffolds can provide an efficient strategy to control the complex and dynamic regulation of cellular processes in a three-dimensional microenvironment. In this study, hybrid scaffolds of collagen and poly(lactic- co-glycolic acid) microbeads were prepared by introducing insulin-releasing poly(lactic- co-glycolic acid) microbeads into collagen porous scaffolds. Insulin-incorporated poly(lactic- co-glycolic acid) microbeads of two distinct sizes, 19.4 ± 1.6 and 4.4 ± 0.9 µm, were used to prepare the hybrid scaffolds. The scaffolds had controlled pore structure, and the poly(lactic- co-glycolic acid) microbeads were well distributed on the pore walls of the scaffolds. The scaffolds had a lower initial burst and a more stable insulin release than did the free microbeads. Culture of human dermal fibroblasts in the hybrid scaffolds were affected the bioactivity of released insulin. The hybrid scaffold prepared with 19.4 ± 1.6 µm microbeads had a more linear release of insulin and a higher promotion effect on cell proliferation than did the other hybrid group and control scaffolds. The hybrid scaffold should be useful for skin tissue engineering.

Abstract
Chitosan/nano-hydroxyapatite membranes with negative charges were fabricated by grid-controlled constant voltage corona charging, and the charged membranes were investigated for cell biocompatibility and osteoinduction. The osteoblasts on the chitosan/nano-hydroxyapatite composite electret membranes significantly enhanced the adhesion, proliferation, and differentiation capacity compared to the uncharged group. This study not only provides evidence for the potential clinical application of our novel membranes but also could be used as a strategy for chitosan/nano-hydroxyapatite scaffolds.

Abstract
Appropriate pore structures and mechanical properties are required for scaffolds that are used for tissue engineering and regenerative medicine. In this study, pre-prepared ice particulates were used as a porogen material to prepare collagen porous scaffolds with well-controlled pore structures and improved mechanical properties. Porogen ice particulates initiated the formation of interconnected large spherical pores surrounded by small pores. The large spherical pores were well compacted and increased the elastic modulus of the scaffolds. The unique pore structures facilitated cell penetration, resulting in a homogeneous cell distribution throughout the scaffolds. The excellent mechanical properties protected the scaffolds from deformation during cell culturing and implantation. The collagen porous scaffolds facilitated cartilage regeneration when bovine articular chondrocytes were cultured in these scaffolds. The use of pre-prepared ice particulates as a porogen material proved to be a useful method to control the pore structure and improve the mechanical properties of collagen-based porous scaffolds.
