The study tested contrastive (DINO), masked-based generative (MAE, iTPN), and hybrid (DINOv2) models pretrained on the JUMP–CP dataset, which contains 119,876 compounds and approximately 1.77 million images from 7 laboratories.\n\nThe results show that top-performing SSL models, specifically DINO and DINOv2, outperformed the classical CellProfiler tool in compound-replicate retrieval on the held-out JUMP–Target2 set with statistical significance (P ≤ 0.001). On the EU-OPENSCREEN Bioactives dataset, these models achieved 31–37% gains in mean average precision for mechanism-of-action retrieval compared to CellProfiler. The study highlights that contrastive and hybrid approaches generalize better across diverse cell types and perturbations than masked-based models.\n\nThis work provides a systematic benchmark for selecting SSL approaches in high-content imaging. By bypassing the need for cell segmentation and handcrafted feature engineering, these pretrained foundation models offer a scalable path to accelerate drug discovery. The authors note that while postprocessing steps like Harmony improved batch effect correction, aligning data across different laboratories remains a challenge.","keyPoints":["DINO and DINOv2 outperformed CellProfiler in compound retrieval on JUMP–Target2 with P ≤ 0.001.","Models achieved 31–37% mean average precision gains on EU-OPENSCREEN Bioactives dataset.","Evaluation used 119,876 compounds and 1.77 million images from the JUMP–CP dataset."],"whyItMatters":"This research validates self-supervised learning as a superior alternative to classical feature engineering for high-content imaging.
