New human cell atlases track how tissues develop

Two new human cell atlases have mapped the molecular machinery that builds tissue in the weeks after conception — and could eventually point the way to addressing developmental disorders.

The researchers behind the atlases say their method for single-cell analysis, detailed in a pair of studies published by the journal Science, could dramatically accelerate efforts to trace how individual cells develop from the embryo to adulthood.

“The key point is that the method scales exponentially,” said University of Washington geneticist Jay Shendure, a senior author for both studies. “When you think about the human body, there’s 37 trillion cells. To really get the kind of comprehensive atlases that we want, we want this kind of scalability.”

Study co-author Dan Doherty, a UW pediatrics professor, compared the procedure’s promise to the impact of the Hubble Space Telescope or the Human Genome Project. “Single-cell methods — it’s hard to overestimate their importance for understanding developmental biology,” he said. “They’re really giving us a picture that we’ve never seen before.”
