The human small intestine. Grace Burgin, Noga Rogel & Moshe Biton, Klarman Cell Observatory, Broad Institute An ambitious project to map the estimated 37.2 trillion cells in the human body is one step closer to fruition. Conceived in 2016, the 3,600-member Human Cell Atlas consortium published a trove of papers in Nature Wednesday with data and insights on some 62 million cells across different biological networks, including the gut and immune system, and how they change across distinct ancestries, ages, and in diseases. The atlas aims to be a “Wikipedia” for the body’s building blocks, and Nature argued that governments should fund it indefinitely, the way they do for other scientific and technical “projects of national or international importance.” |
