Topographical and Chemical Inductive Cues Synergistically Enhance the Schwann Cell Differentiation of Aligned Dental Pulp Stem Cell Sheets.
Article in Journal of tissue engineering and regenerative medicine, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Peripheral nerves have an inherent capacity for regeneration, but these Schwann cell-mediated mechanisms are insufficient for severe injuries. With current clinical treatments, slow regeneration and aberrant reinnervation result in poor functional outcomes. Dental pulp stem cells (DPSCs) offer a promising source of therapeutic neurotrophic factors (NTFs), growth factors that stimulate axon regeneration. Previously, we established that DPSCs can generate scaffold-free sheets with a linearly aligned extracellular matrix (ECM). These sheets provide trophic cues via the DPSCs and directional cues through the aligned ECM to both accelerate and orient axon outgrowth, thus providing a biomaterial capable of addressing the current clinical challenges. DPSCs have a propensity for differentiating into Schwann cells (SC-DPSCs), further enhancing their endogenous NTF expression. Here, we evaluated the effect of inducing SC differentiation on the neuroregenerative bioactivity of our DPSC sheets. These sheets were formed on substrates with linear microgrooves to direct the cells to deposit an aligned ECM. Inducing differentiation using an SC differentiation medium (SCDM) increased NTF expression 2-fold compared to unaligned uDPSC sheets, and this effect was amplified in linearly oriented SC-DPSC sheets by up to 8-fold. Furthermore, these aligned SC-DPSC sheets remodeled the sheet ECM to more closely emulate a regenerative neural microenvironment, expressing 8-fold and 2 × 10
