A 3D model to evaluate cell chemotaxis within a heterogenic tumor microenvironment.
Article in Lab on a chip, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
As studies continue to bring forward data on both the complexity and heterogeneity behind the tumor microenvironment, new strategies to understand and unravel the cellular interactions that regulate tumor progression and tumor cell invasion are required. Here, we present a novel and tailorable 4-well 3D culture chamber design capable of studying chemotaxis between several distinct cell types and a cancer cell population of interest. The use of a type I collagen hydrogel as the 3D substrate allowed for a differential molecule diffusion, in which rate of diffusion was associated with molecular weight. When culturing different human stromal cells (hASCs, hDMECs and hDFbs) in the outer wells while keeping VMM15 melanoma cells within the central well it was observed that hASCs and hDFbs presented directional migration throughout the collagen matrix towards the tumor cells. Further analysis revealed a higher area of migration present in the hDFbs when compared to the hASCs, supporting the potential of this system to study the recruitment of supporting cells by cancer cells and how this may impact tumor invasion.
