Systemic humoral activation facilitates tissue regeneration by D-chiral biomaterial scaffolds.
Article in Cell biomaterials, 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
Biomaterial design increasingly considers how adaptive immunity influences tissue regeneration, yet most efforts have focused on T lymphocyte responses. Here, we show that D-chiral Microporous Annealed Particle (DMAP) scaffolds promote dermal appendage regeneration through engagement of humoral immunity. In a splinted full-thickness wound model, DMAP supported regeneration even when lymphocyte infiltration was restricted, indicating that infiltrating adaptive immune cells are not strictly required. Instead, DMAP activated B cells in the skin draining lymph nodes, driving germinal center formation and the production of biomaterial-specific antibodies alongside pro-regenerative systemic factors. This circulating milieu was sufficient to confer regenerative healing in wounds treated with biomaterials that promote collagen repair but not hair follicle regeneration. Together, these findings establish humoral immunity as a central component of biomaterial-induced regeneration and highlight new opportunities to harness systemic factors for tissue repair.
