Breast cancer brain metastasis: evaluating the effectiveness of alginate-based organoids in metastasis modeling to replace matrigel.
Article in BMC research notes, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
backgroundOne of the most important and devastating side effects of breast cancer is brain metastasis. Our understanding of cancer heterogeneity is revolutionized by tumoral organoids and seems promising for personalized medicine. This study aimed to generate a hydrogel-based brain metastasis organoid.
methodsMouse brain metastatic tumor cells (4T1B) were isolated and cultured from the brain metastasis lesions of mice with breast cancer. Different hydrogels, including alginate, carboxymethylcellulose, gelatin, collagen, and matrigel, were prepared. Pre-coated hydrogels in 96-well plates were treated with 4T1B cells. The morphology and viability of metastatic organoids were analyzed after 7 days.
resultsAccording to our results, 4T1B cells formed semi-regular cluster structures in alginate hydrogel. In this group, the cell survival rate and formation of three-dimensional structures were significantly higher than in other groups.
conclusionFor organoid cultures, there's a lot of research on natural and synthetic scaffolds that are chemically or mechanically well-designed. In the present study, we used highly brain metastatic tumor cells and detected that alginate hydrogel is the best choice for organoid formation and breast cancer brain metastasis modeling.
