A Microwell Platform for Characterizing the Dynamic Response of Corneal Keratocytes to Biochemical and Biophysical Cues.
Article in Micromachines, 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
The interaction of corneal keratocytes with biochemical (e.g., composition, growth factors) and biophysical (e.g., topography) cues present in the cornea regulates their morphology during normal homeostasis and wound healing. In this study, we developed a novel method of fabricating substrates with micropatterns of Type I aligned collagen fibrils in a 6-well format that allowed for time-lapse imaging of dynamic changes in keratocyte morphology. Culturing keratocytes on aligned collagen fibrils in the presence of platelet-derived growth factor BB (PDGF-BB) allowed us to characterize the dynamics of cell alignment and migration. To investigate the roles of topography and protein composition on the dynamic features of cell spreading, cell protrusions, and cell motility, we cultured keratocytes on either hydrophobic-coated glass, aligned collagen fibrils, or monomeric collagen with or without a fibronectin coating. The presence of a fibronectin coating delayed the formation of cell protrusions during spreading on all of the substrates tested (e.g., Aquasil-coated glass, monomeric collagen, aligned collagen fibrils), while the presence of aligned collagen fibrils resulted in a ~2-fold reduction in the cell spreading area. The experimental platform developed here allows for parallel experiments and real-time imaging and thus providing a valuable new tool to study the dynamic activity and cell-substrate interactions of corneal keratocytes. This approach will allow for systematic screening of the response of keratocytes and other cell types (e.g., tenocytes, cardiomyocytes, cancer cells) that normally are exposed to aligned collagen topographies.
