Abstract
To improve bone regeneration in oral microenvironment, we generated a novel biodegradable, antibacterial, and osteoconductive electrospun PLGA/PCL membrane as an ideal osteogenic scaffold. The novel three-layer membranes were structured with serial layers of electrospun chlorhexidine-doped-PLGA/PCL (PPC), PLGA/PCL (PP), and β-tricalcium phosphate-doped-PLGA/PCL (PPβ). To characterize osteoconductive properties of these membranes, MC3T3-E1 (MC) cultures were seeded onto the membranes for 14 days for evaluation of cell proliferation, morphology and gene/protein expression. In addition, MC cells were cultured onto different surfaces of the three-layer membranes, PPC layer facing MC cells (PPβ-PP-PPC) and PPβ layer facing MC cells (PPC-PP-PPβ) to evaluate surface-material effects. Membrane properties and structures were evaluated. Antibacterial properties against Streptococcus mutans and Staphylococcus aureus were determined. Scanning electron microscope demonstrated smaller interfiber spaces of PPC and PPβ-PP-PPC compared to PPβ, PPC-PP-PPβ, and PP. PPC and PPβ-PP-PPC exhibited hydrophilic property. The three-layer membranes (PPC-PP-PPβ and PPβ-PP-PPC) demonstrated significantly higher Young's modulus (94.99 ± 4.03 MPa and 92.88 ± 4.03 MPa) compared to PP (48.76 ± 18.15 MPa) or PPC (7.92 ± 3.97 MPa) (p < 0.05). No significant difference of cell proliferation was found among any groups at any time point (p > 0.05). Higher expression of integrins were detected at 12 h of cultures on PPC-PP-PPβ compared to the controls. Promoted osteoconductive effects of PPC-PP-PPβ were revealed by alkaline phosphatase assays and Western blot compared with the controls at 7 and 14 days. PPC, PPC-PP-PPβ and PPβ-PP-PPC exhibited a significantly wider antibacterial zone against the tested bacteria compared to PP and PPβ (p < 0.05). These results suggested that the three-layer electrospun membranes demonstrated superior properties: higher strength, better cell adhesion, and promoted osteoconductive properties compared to single-layer membrane: however, antibacterial properties were exhibited in three-layer electrospun membranes and chlorhexidine-doped single-layer membrane. We concluded that the novel three-layer membranes could be used as a biocompatible scaffold for intraoral bone regeneration due to its enhanced osteoconductive activity and antibacterial effect.

Abstract
Zinc (Zn) and its alloys have recently been introduced as a new class of biodegradable metals with potential application in biodegradable vascular stents. Although an in vivo feasibility study pointed to outstanding biocompatibility of Zn-based implants in vascular environments, a thorough understanding of how Zn and Zn2+ affect surrounding cells is lacking. In this comparative study, three vascular cell types-human endothelial cells (HAEC), human aortic smooth muscle cells (AoSMC), and human dermal fibroblasts (hDF)-were studied to advance the understanding of Zn/Zn2+-cell interactions. Aqueous cytotoxicity using a Zn2+ insult assay resulted in LD50 values of 50 µM for hDF, 70 µM for AoSMC, and 265 µM for HAEC. Direct cell contact with the metallic Zn surface resulted initially in cell attachment, but was quickly followed by cell death. After modification of the Zn surface using a layer of gelatin-intended to mimic a protein layer seen in vivo-the cells were able to attach and proliferate on the Zn surface. Further experiments demonstrated a Zn dose-dependent effect on cell spreading and migration, suggesting that both adhesion and cell mobility may be hindered by free Zn2+.

Abstract
Dense zirconia ceramics are used in bone applications due to their mechanical strength and biocompatibility, but lack osseointegration. A porous interface in contact with bone tissue may lead to better bone bonding but the biological properties of porous zirconia are not widely explored. The present study focuses on the manufacturing of an yttria- (YSZ) and a magnesia-stabilized (MgSZ) porous zirconia, and on their in vitro biological investigation. The sintered ceramics had similar characteristics of porosity, pore size and interconnectivity. Their elastic moduli and compressive strength values were within the range of the values of human cortical bone. MC3T3-E1 pre-osteoblasts were used to investigate the proliferation, alkaline phosphatase (ALP) activity, collagen deposition and expression profile of four genes involved in bone metabolism of cells on porous ceramics. Scanning electron and fluorescence microscopy were employed to visualize cell morphology and growth. Pre-osteoblasts adhered well on both ceramics but cell numbers on YSZ were higher. Cells exhibited an increase in ALP activity and collagen deposition after 14 days on both MgSZ and YSZ, with higher levels on YSZ. Real-time quantitative polymerase chain reaction (qPCR) showed that the expression of bone sialoprotein (Bsp) and collagen type I (col1aI) were significantly higher on YSZ. No significant differences were found in their ability to regulate the early gene expression of Runx2 and Alp. Nevertheless, the biomineralized calcium content was similar on both ceramics after 21 days, indicating that despite chemical differences, both scaffolds direct the pre-osteoblasts toward a mature state capable of mineralizing the extracellular matrix.

Abstract
Osseointegration of bone implants is a vital part of the recovery process. Numerous studies have shown that micropatterned geometries can promote cell-substrate associations and strengthen the bond between tissue and the implanted material. As demonstrated previously, exogenous zinc levels can influence the responsiveness of pre-osteoblasts to micropatterns and modify their migratory behavior. In this study, we sought to determine the effect of exogenous zinc on differentiation of osteoblasts cultured on micropatterned vs. planar substrates. Levels of activated metalloproteinase-2 (MMP-2) and transforming growth factor-beta 1 (TGF-β1), as well as early stage differentiation marker alkaline phosphatase, were altered with the addition of zinc. These results suggest that exogenous zinc concentration and micropatterning may interdependently modulate osteoblast differentiation.
