Special Issue Information

Dear Colleagues,

In recent years, enormous growth in nano-material technology and science has been attained in the biomedical filed. For example, nanosized hydrogels, so-called nanogels, have been reported to provide a feasible drug-delivery system that enables the efficient transfer of chemotherapeutics and short interfering RNA, and slow-release anti-bacterial peptide, growth factors and cytokines on-site. Through the functions, nanogels can inhibit tumor growth, and enhance wound-healing and blood vessel regeneration. Moreover, nanogels are also used as a scaffold for tissue engineering, including bone, cardiac and urethra tissue regeneration. In general, nanogels are highly biocompatible and biodegradable. Nanogels are also considered to be excellent scaffolds for preparing composites as a novel class of advanced materials, which comprise both nanogels and other constituents, such as polymers or inorganic nanoparticles. Thus, the development of nanogels and their effective application will play an important role in the regenerative medicine field.

This Special Issue will provide various reports on the leading edge nanogels’ synthesis and their effective application in regenerative medicine.

Novel functional biomaterials are expected to bring about breakthroughs in developing immunotherapy and regenerative medicine through their application as drug delivery systems and scaffolds. Nanogels are defined as nanoparticles with a particle size of 100 nm or less and as having a gel structure. Nanogels have a three-dimensional network structure of cross-linked polymer chains, which have a high water content, a volume phase transition much faster than that of a macrogel, and a quick response to external stimuli. As it is possible to transmit substances according to the three-dimensional mesh size of the gel, a major feature is that relatively large substances, such as proteins and nucleic acids, can be taken into the gel. Furthermore, by organizing nanogels as a building block, they can be applied as a scaffold material for tissue regeneration. This review provides a brief overview of the current developments in nanogels in general, especially drug delivery, therapeutic applications, and tissue engineering. In particular, polysaccharide-based nanogels are interesting because they have excellent complexation properties and are highly biocompatible. Full article

Title: Glucan dendrimer-nanogel mediated OC-STAMP silencing for treatment of pathogenic bone resorption

Abstract: Osteoclasts-stimulatory trans-membrane protein (OC-STAMP) plays a pivotal role in promotion of cell fusion event during osteoclast-differentiation (osteoclastogenesis) in the context of pathogenic bone resorption. Thus, it is plausible that the bioengineered approach that suppresses OC-STAMP expression can lead to the development of an effective treatment for inflammatory bone resorption diseases, with minimum side effects. Here, we compared two types of novel amphiphilic glucan dendrimer (GD) nanogels (with or without C12) as a carrier of short interfering RNA (siRNA) to silence OC-STAMP. The results showed that C12-GD nanogels is more efficient in the in vitro silencing of OC-STAMP than GD-nanogel, and that local injection of anti-OC-STAMP-siRNA /C12-GD nanogel complex could attenuate bone resorption induced in the mouse model of periodontitis.
