Innovative MXene/SilMA-Based Conductive Bioink for Three Dimensional Bioprinting of Neural Stem Cell Spheroids in Neural Tissue Engineering.
Article in ACS applied materials & interfaces, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
Conductive bioinks, integrated with 3D bioprinting and electrical stimulation, are essential for advancing neural tissue engineering. This study developed a SilMA/Pectin/MXene-soybean phospholipids (SP) bioink, where SilMA (silk fibroin modified with glycidyl methacrylate) provides a structural base, pectin enhances printability and shear-thinning properties, and MXene-SP improves conductivity through superior dispersibility. Increasing pectin and MXene-SP concentrations reduced the hydrogel's Young's modulus, promoting neural stem cell (NSC) differentiation into neurons. Electrochemical analyses revealed that higher MXene-SP levels decreased impedance and increased redox current, while conductivity measurements showed improved performance compared to unmodified MXene. NSCs encapsulated in the bioink achieved maximum proliferation under electrical stimulation at 300 μA for 10 min daily over 5 days. Neuronal differentiation positively correlated with MXene-SP concentration and stimulation intensity. Synaptic activity and vesicle recycling, assessed using FM1-43 dye, were significantly enhanced under electrical stimulation. This study successfully developed a biocompatible conductive bioink capable of inducing neuronal differentiation. Electrical stimulation further promoted cell proliferation, neuronal differentiation, and enhanced synaptic function. This bioink shows great potential for future applications in neural tissue engineering.
