Special Issue Information

Dear Colleagues,

The rapid development of new approaches and techniques in the area of molecular biology has led to new insights in the field of medicine for clinical applications and biomaterial science for tissue engineering approaches. More specifically, investigative methods of molecular biology have made inroads into uncovering fundamental medical processes that are revealed when we fully understand their molecular details. Cloning tools, CRISPR/Cas9 technology, DNA arrays and next-generation sequencing (nGS) are some of the molecular biology tools used in in guiding drug discovery and development diagnostic methods. The information that arises thanks to the above genetic tools in addition to patients’ reported outcomes covers all the elements that we have to take into consideration in routine clinical decision-making strategies in order to optimize the treatment benefit for patients. Additionally, as molecular biologists progressively discover the pathogenetic mechanisms that underly several entities, evidence regarding the correct combination of extracellular and intracellular chemical gradients, cellular attachements complexes and other stimuli required to activate tissue regeneration is revealed. The aim of this Special Issue is to gather all the relevant new insights and updates from the field of medicine, biomaterials and tissue engineering under the prism of molecular biology tools in order to obtain a more comprehensive view of the obstacles and challenges that are raised.

Abstract

The ion doping of mesoporous silica nanoparticles (MSNs) has played an important role in revolutionizing several materials applied in medicine and dentistry by enhancing their antibacterial and regenerative properties. Mineral trioxide aggregate (MTA) is a dental material widely used in vital pulp therapies with high success rates. The aim of this study was to investigate the effect of the modification of MTA with cerium (Ce)- or calcium (Ca)-doped MSNs on the biological behavior of human gingival fibroblasts (hGFs). MSNs were synthesized via sol–gel, doped with Ce and Ca ions, and mixed with MTA at three ratios each. Powder specimens were characterized using Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and scanning electron microscopy (SEM). Biocompatibility was evaluated using a 3-[4,5-dimethylthiazol-2-yl]-2,5 diphenyl tetrazolium bromide (MTT) assay following hGFs’ incubation in serial dilutions of material eluates. Antioxidant status was evaluated using Cayman’s antioxidant assay after incubating hGFs with material disc specimens, and cell attachment following dehydration fixation was observed through SEM. Material characterization confirmed the presence of mesoporous structures. Biological behavior and antioxidant capacity were enhanced in all cases with a statistically significant increase in CeMTA 50.50. The application of modified MTA with cerium-doped MSNs offers a promising strategy for vital pulp therapies. Full article

Abstract

Numerous surgeries are carried out to replace tissues that have been harmed by an illness or an accident. Due to various surgical interventions and the requirement of bone substitutes, the emerging field of bone tissue engineering attempts to repair damaged tissues with the help of scaffolds. These scaffolds act as template for bone regeneration by controlling the development of new cells. For the creation of functional tissues and organs, there are three elements of bone tissue engineering that play very crucial role: cells, signals and scaffolds. For the achievement of these aims, various types of natural polymers, like chitosan, chitin, cellulose, albumin and silk fibroin, have been used for the preparation of scaffolds. Scaffolds produced from natural polymers have many advantages: they are less immunogenic as well as being biodegradable, biocompatible, non-toxic and cost effective. The hierarchal structure of bone, from microscale to nanoscale, is mostly made up of organic and inorganic components like nanohydroxyapatite and collagen components. This review paper summarizes the knowledge and updates the information about the use of natural polymers for the preparation of scaffolds, with their application in recent research trends and development in the area of bone tissue engineering (BTE). The article extensively explores the related research to analyze the advancement of nanotechnology for the treatment of bone-related diseases and bone repair. Full article
