Differential expression of osteoblast-like cells on self-organized titanium dioxide nanotubes.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background/purpose: Titanium dioxide nanotube (TNT) structures have been shown to enhance the early osseointegration of dental implants. Nevertheless, the optimal nanotube diameter for promoting osteogenesis remains unclear due to variations in cell types and manufacture of nanotubes. This study aimed to evaluate the differences in MC3T3-E1 and Saos-2 cells behavior on nanotubes of varying diameters. Materials and methods: TNT structures were fabricated by anodizing titanium foil at voltages ranging from 15V to 70V and annealed at 450 °C. Surface morphology and wettability were characterized using field emission scanning electron microscopy and water contact angle measurements, respectively. MC3T3-E1 and Saos-2 cells were cultured to evaluate biocompatibility. Early cell morphology and adhesion were visualized by scanning electron microscopy. Cell proliferation was quantified using CCK-8 assays, and differentiation was assessed through alkaline phosphatase assays. Osteogenesis-related gene expression was analyzed by real-time polymerase chain reaction (PCR), measuring runt-related transcription factor 2 (Runx-2), alkaline phosphatase (ALP), collagen type 1 (COL-1), osteocalcin (OCN), and Osteopontin (OPN) gene levels. Results: Our results found that Saos-2 cells may be more suitable for TNT-related studies compared to MC3T3-E1 cells. Notably, the 65V nanotube group, with a diameter of 135.9 ± 15.83 nm, demonstrated the most significant osteogenic effect in our assays. Conclusion: We propose that the use and screening of multiple cell lines prior to the evaluation of biomaterials can lead to more accurate in vitro experiments, thereby enhancing the reliability of biomaterial research.
