Strengthen Multiplex IHC Antibody Validation

	Digital Pathology & Histology
	The latest digital pathology & histology news from AZoNetwork

Reliable multiplex IHC starts with rigorous antibody validation. Cross-reactivity, lot variation, over-concentration and FFPE incompatibility can produce convincing images while introducing misleading biological signals. Discover best practices for identifying these hidden failure modes, improving antibody reproducibility and strengthening confidence in staining data used for digital pathology and tissue analysis workflows.

			Deep-learning tissue clocks reveal how organs age and leave disease-linked signals in blood Deep learning applied to more than 25,000 histopathology slides revealed tissue-specific structural signatures of biological aging that tracked telomere attrition, pathology, comorbidity, and molecular changes more closely than chronological age alone.

			Microneedle Patches Turn Skin Into a Window for Immune Bioanalysis Researchers combined local restimulation of skin-resident memory T cells with hydrogel-coated microneedle patches to recruit and sample rare immune cells. In mouse models, the approach recovered more antigen-specific T cells than a blood sample or punch biopsy, while studies in humans supported short-term tolerability and proof-of-concept cell sampling.

	AI-based methods help uncover hidden roots of tumor metastasis A cancerous tumor is not a single enemy. It is made up of many different cell populations that can behave in very different ways.

	Combined bio-histological score prevents overtreatment in liver transplant patients Long‑term outcomes after liver transplantation remain hampered by complications linked to intensive immunosuppression—infections, cardiovascular events, kidney dysfunction, and metabolic disorders affect 10% to 40% of recipients.

	AI model predicts cancer subtype, genetic mutations, and survival outcomes across 32 solid tumors Researchers have developed a novel AI model that can analyze a routine whole histopathology image and simultaneously predict cancer subtype, specific genetic mutations, and survival outcomes across 32 different solid cancers rather than focusing on a single cancer type.

	How AI Predicts Molecular Biomarkers From H&E Slides AI advancements in digital pathology enable the prediction of molecular biomarkers from routine H&E slides, transforming histopathology and treatment response.

	AI-based "tissue clocks" measure the biological age of human organs AI-based "tissue clocks" can estimate the biological age of human organs from histological images, researchers at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences and the Ludwig Boltzmann Institute for Network Medicine (LBI-NetMed) at the University of Vienna showed.

	A closer look at Parkinson’s brains finds tau where standard tests saw little Researchers used single-molecule and super-resolution imaging to profile protein aggregates across six brain regions from 29 post-mortem donors, detecting high-intensity phosphorylated tau aggregates in the Parkinson’s disease putamen despite negligible conventional tau staining.

	Molecular mapping reveals hidden cellular programs in heart transplant rejection A new study that explores gene expression during heart transplant rejection marks a step forward for precision medicine approaches to treat organ rejection.
