![]() Therefore, according to the results of this study, the core-shell scaffold containing PRF can be a good suggestion for use in biomedical applications. Due to the present of PRF in the scaffold B, the bone cells growth and cells adhesion on the surface of scaffold B increased compared to the scaffold A. Type I collagen has been chosen as base material for the development of the entire core-shell scaffold because it is the major structural protein in most of the soft tissues, thus possessing the ability to assist tissue remodeling and to be resorbed along time by enzymatic action (Browne et al., 2013). In this paper, we replaced mesoporous TiO 2 nanoparticles scaffold layers by BaTiO 3-coated TiO 2 coreshell nanoparticles films which obtained by treating pure mesoporous TiO 2 layers with 1.0 wt barium nitrate solution, successfully realized the aim of optimizing interfaces bonding at TiO 2 /CH 3 NH 3 PbI 3. ![]() Cell viability and adherence of bone cells on the surface scaffolds were evaluated via MTT assay. Also, the presence of chitosan containing PRF in the core with the formation of hydrogen bonding with polycaprolactone in the shell of the scaffold B caused a scaffold with excellent mechanical properties and elastic modulus 40 MPa. The average fibers diameter of the scaffold B decreased to 160 nm as compared to 179 nm for the scaffold A. Surface morphology, fiber diameter, porosity, mechanical properties, and functional groups on the scaffolds surface were evaluated by scanning electron microscope (SEM) and transition electron microscopy (TEM), displacement liquid method, tensile strength test, and fourier transform infrared (FTIR) spectroscopy, respectively. High-throughput assays of human tissue responses. The use of non-invasive scaffold materials which can mimic the innate piezoelectric properties of biological tissues is a promising strategy to promote native tissue regeneration. Resulting from the collagen's biocompatibility, the as-prepared scaffold possessed better biological efficacy to promote cell attachment and penetration since the cells mainly contact with the fiber's shell. ![]() In this study, polycaprolactone/chitosan (scaffold A) and polycaprolactone/chitosan core-shell scaffold containing PRF (scaffold B) were fabricated by uniaxial electrospinning and coaxial electrospinning methods, respectively and were characterized. These results suggest that co-culture of hepatocytes and fibroblasts embedded in the 3D core-shell scaffold is a good model of the liver in vitro and has a balance of homotypic and heterotypic cell-cell interactions, which are beneficial for the expressions of their liver-specific functions. 2020) developed a simple method to fabricate core-shell hydrogel fibers/scaffolds with controlled drug delivery and designed structures to manage residual. 92 prepared a calcium silicate core-shell structure scaffold containing different mass fractions of Mg ions by a coaxially aligned bilayer nozzle device (Figure 4 D), and the presence. The core/shell fiber can bring many advantages to the scaffold by acquiring PCL and collagen's strong point and overcoming their weakness. Platelet-rich fibrin (PRF) is a natural fibrin matrix containing platelets and growth factors in the blood that increases the bone tissue repair.
