Abstract In order to obtain larger, clinical-scale and practical-scale bone grafts, we have designed both tailored scaffolds and tailored bio incubator with optimal bio-production characteristics. Using DIC files to Simpleware Scan-IP (Simple-ware-exeter United Kingdom), we have digitally reconstructed segmental additive bone-tissue in order to perform images processing. Both hydroxyapatite and tannin composites have been used in order to get the final bone modules combined for retexturing of segmental bone defect. We have found that sectioning of bone segment deficiency reorganizations into well disk-shaped design permits one to standardize the cell culture and seeding protocol, to get More >

Abstract Tissue engineering’s main goal is to regenerate or replace tissues or organs that have been destroyed by disease, injury, or congenital disabilities. Tissue engineering now uses artificial supporting structures called scaffolds to restore damaged tissues and organs. These are utilized to attach the right cells and then grow them. Rapid prototyping appears to be the most promising technology due to its high level of precision and control. Bone tissue replacement “scaffolding” is a common theme discussed in this article. The fused deposition technique was used to construct our scaffold, and a polymer called polylactic acids… More > Graphic Abstract

Abstract The limited bioactivity of scaffold materials is an important factor that restricts the development of bone tissue engineering. Wnt3a activates the classic Wnt/β-catenin signaling pathway which effects bone growth and development by the accumulation of β-catenin in the nucleus. In this study, we fabricated 3D printed PCL scaffold with Wnt3a-induced murine bone marrow-derived stromal cell line ST2 decellularized matrix (Wnt3a-ST2-dCM-PCL) and ST2 decellularized matrix (ST2-dCM-PCL) by freeze-thaw cycle and DNase decellularization treatment which efficiently decellularized >90% DNA while preserved most protein. Compared to ST2-dCM-PCL, Wnt3a-ST2-dCM-PCL significantly enhanced newly-seeded ST2 proliferation, osteogenic differentiation and upregulated osteogenic More >

Abstract β-TCP-Zirconia scaffolds with different architectures were fabricated by means of 3D-Bioplotting in order to enhance the mechanical and in-vitro ability of the scaffold to heal large size bone defects. In the present study scaffold architecture with different strand orientations (0°-90°, 0°-45°-135°-180°, 0°-108°-216° and 0°-72°-144°-36°-108°) were fabricated, characterized and evaluated for mechanical strength and cell proliferation ability. β-TCP powder (25 µm) and PVA (Polyvinyl Alcohol) was acquired from Fisher Scientific, India. Zirconia (18 to 32 µm) was procured from Lobachemie, India. In brief 7.5%, PVA in distilled water was used as a binder and was mixed… More >
