A partially automated method for DNA extraction from marmoset hair follicles to avoid blood chimerism.
Article in Frontiers in genetics, 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
Marmosets are valuable non-human primate models, however their unique reproduction results in high levels of blood chimerism, making blood unreliable for DNA sequencing. Hair follicles have lower levels of chimerism however DNA extraction from hair follicles is challenging due to the limited tissue. We developed a non-invasive, partially automated protocol for hair follicle collection and DNA extraction scalable to hundreds of samples. This method uses a proteinase K cell lysis solution in conjunction with Promega's Maxwell RSC's paramagnetic silica-based particles to purify DNA. We applied this protocol to samples collected from over 300 animals and from two different species. We were able to generate high quality libraries for whole genome sequencing (WGS) from approximately 150 hair follicles. Libraries built from >0.15 µg DNA had an average duplication rate of 0.19, analogous to libraries built from blood. Sequenced DNA had average chimerism rates of 2.3%. DNA extraction from hair follicles offers a reliable method for whole genome sequencing with minimal chimerism. The partial automation improves efficiency by reducing lab time and extraction variability. The protocol is applicable to a range of projects requiring low-input DNA sources or automated, high-throughput sample processing. Peer review data availability: Data on DNA yields and resulting whole genome sequencing libraries are provided as Supplementary Tables. The raw whole genome sequencing data produced from these libraries are archived online at the NIH Sequence Read Archive.
