• Abstract: Chemical staining methods are dependable but require extensive time, expensive chemicals, and raise environmental concerns. These challenges highlight the need for alternative solutions like virtual staining, which accelerates the diagnostic process and enhances stain application flexibility. Generative AI technologies are pivotal in addressing these issues. However, the high-stakes nature of healthcare decisions, especially in computational pathology, complicates the adoption of these tools due to their opaque processes. Our work introduces the use of generative AI for virtual staining, aiming to enhance performance, trustworthiness, scalability, and adaptability in computational pathology. The methodology centers on a singular H&E encoder supporting multiple stain decoders. This design focuses on critical regions in the latent space of H&E, enabling precise synthetic stain generation. Our method, tested to generate 8 different stains from a single H&E slide, offers scalability by loading only necessary model components during production. We integrate label-free knowledge in training, using loss functions and regularization to minimize artifacts, thus improving paired/unpaired virtual staining accuracy. To build trust, we use real-time self-inspection with discriminators for each stain type, providing pathologists with confidence heat-maps. Automatic quality checks on new H&E slides ensure conformity to the trained distribution, ensuring accurate synthetic stains. Recognizing pathologists' challenges with new technologies, we have developed an open-source, cloud-based system, that allows easy virtual staining of H&E slides through a browser, addressing hardware/software issues and facilitating real-time user feedback. We also curated a novel dataset of 8 paired H&E/stains related to pediatric Crohn's disease, comprising 480 WSIs to further stimulate computational pathology research.

  Immunohistochemical (IHC) stains play a vital role in a pathologist's analysis of medical images, providing crucial diagnostic information for various diseases. Virtual staining from hematoxylin and eosin (H&E)-stained whole slide images (WSIs) allows the automatic production of other useful IHC stains without the expensive physical staining process. Current virtual WSI generation methods based on tile-wise processing often suffer from inconsistencies in content, texture, and color at tile boundaries. We propose a novel consistent WSI synthesis network, CC-WSI-Net, that extends GAN models to
