A Sneeze Shouldn't Ruin an AI Model: Why Portrai is Automating Visium HD with ABLE Labs
Spatial Transcriptomics (ST) is changing the landscape of precision oncology by decoding both the location and gene expression of cells simultaneously. Yet, behind the stunning AI-generated maps...
Integrating Spatial Transcriptomics and Drug Imaging: A New Paradigm for Evaluating Precision Drug Delivery Systems
Portrai’s Next Step in Precision DDS When designing precision drug delivery systems (DDS), the key question is no longer simply, “Does the drug reach the tumor?”
20 µm Distance and 150 µm Boundary: When Spatial Metrics Split Treatment Response
Returning to “Same Stage, Different Destiny” In my previous post, I wrote that TNM staging is an excellent method of assessment, but it cannot fully describe the blueprint of a tumor—namely, the…
