Care Framework & Diagram
It turns out 'the same type of cell' contains dozens of completely different individuals — only visible at single-cell resolution
By the Editors Care Framework & Diagram
Old approach: measure the average signal from millions of cells at once. New approach: read each individual cell’s full profile separately.

Many More Cell Types Than We Thought
What used to be called simply a ‘CD8+ T cell’ turns out to be 15–20 distinct functional subtypes. NK cells and macrophages show the same hidden diversity — old category names were hiding real biology.

Watching Cells Change, Not Just Snapshotting Them
New tools track where a cell is heading, not just what it is right now — revealing the exact fork in the road where a T cell decides to become exhausted, while there’s still time to intervene.

Mapping Cell-to-Cell Conversations
Instead of just noting ‘this signal is elevated,’ these tools show which specific cell sends a suppressive signal to which specific receiver — turning a correlation into an actual drug target.
