The Weizmann Institute, Sheba Medical Center and Mayo Clinic mapped thousands of specialised genes, showing the organ has eight functional regions rather than the long-assumed three.
Researchers said the atlas explains why metabolic disease, viral and autoimmune inflammation, liver cancer and metastases tend to arise in different parts of the liver.
The team said single-cell RNA mapping also showed human liver functions differ from other mammals and could guide targeted treatments and similar atlases for other organs.
With the liver's disease hotspots now mapped, can we design drugs that target only the most vulnerable cells?
This liver 'blueprint' guides organ printing. When can we expect personalized, rejection-proof transplants?
Human livers process fat differently than other mammals. Does this make us uniquely vulnerable to modern diets?
Breakthrough 2-Micron Resolution Liver Atlas from Healthy Donors Overturns Century-Old Model
Overview
In April 2026, a collaborative team published the first high-resolution digital atlas of the healthy human liver, revealing eight distinct functional zones within liver lobules and providing an accurate baseline by using tissue from healthy living donors. This atlas uncovered significant differences between human and mouse liver organization, challenging traditional animal models. It also illuminated how the human liver's evolved 'thrifty' metabolism, beneficial historically, now predisposes to fat accumulation and mitochondrial dysfunction under modern diets, driving liver diseases like NAFLD. The atlas enables precise diagnostics and guides new therapies, including triple receptor agonists and targeting Kupffer cells, while highlighting the role of the oral-gut-liver axis and fostering global research through open-access tools.
