Abstract—Calcium–magnesium silicate ceramic diopside is an effective carrier of BMP-2 and, in combination with a bovine demineralized bone matrix as a scaffold, can induce effective reparative osteogenesis on the model of craniotomy in mice. It was of interest to investigate the efficacy of combined usage of BMP-2-loaded diopside with recombinant spidroins for the induction of osteogenesis. For this purpose, porous implants were prepared based on recombinant spidroin rS1/9, into which BMP-2 was introduced either as BMP-2 loaded diopside particles suspended in hyaluronic acid or by adsorption. Neo-osteogenesis with bone marrow formation occurred in both groups with BMP-2, most pronounced in the group with BMP-2 and diopside on the model of critical size defects in the cranium in mice. Thus, the use of 3D scaffolds based on recombinant spidroin with BMP2-loaded diopside particles in hyaluronic acid can lead to effective induction of osteogenesis. The spidroin scaffolds themselves represent a sufficiently effective carrier for BMP-2.
期刊介绍:
Applied Biochemistry and Microbiology is an international peer reviewed journal that publishes original articles on biochemistry and microbiology that have or may have practical applications. The studies include: enzymes and mechanisms of enzymatic reactions, biosynthesis of low and high molecular physiologically active compounds; the studies of their structure and properties; biogenesis and pathways of their regulation; metabolism of producers of biologically active compounds, biocatalysis in organic synthesis, applied genetics of microorganisms, applied enzymology; protein and metabolic engineering, biochemical bases of phytoimmunity, applied aspects of biochemical and immunochemical analysis; biodegradation of xenobiotics; biosensors; biomedical research (without clinical studies). Along with experimental works, the journal publishes descriptions of novel research techniques and reviews on selected topics.
