A 3D lymph node model for chronic lymphocytic leukaemia recapitulates microenvironmental features and drug response in vitro.

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
Chronic lymphocytic leukaemia (CLL) cells circulate between the blood, bone marrow (BM) and lymphoid organs, where interactions with the lymph node (LN) microenvironment enhance their survival, proliferation and drug resistance. Most in vitro models fail to reproduce the spatial and cellular complexity of the LN niche, limiting studies of tissue-specific drug responses. To address this, we developed a 3D LN model using a gelatine scaffold and a clinorotator bioreactor previously validated for a BM system. The scaffold was seeded with human lymphatic fibroblasts and endothelial cells, which deposited extracellular matrix and supported patient-derived CLL cell viability and proliferation. Consistent with in vivo observations, CLL cells within the scaffold downregulated the chemokine receptor CXCR4, further reduced upon proliferative stimulation. Final validation involved treatment with targeted therapies: the BCL-2 antagonist venetoclax and the BTK inhibitor ibrutinib. Venetoclax treatment revealed greater CLL protection within the LN environment than in BM, whereas the mobilizing effect of ibrutinib was comparable between these two niches. This 3D LN model offers an effective ex vivo platform for studying microenvironment-tumour interactions and tissue-specific drug responses.
