A panoramic view of cell population dynamics in mammalian aging To elucidate aging-associated cellular population dynamics, we present PanSci, a single-cell transcriptome atlas profiling over 20 million cells from 623 mouse tissues across different life stages, se...


Excited to share our work @science.org. led by our incredible @tommyz626.bsky.social at @rockefelleruniv.bsky.social! By profiling 21 million single cells across life stages, we reveal aging as distinct, development-like transitions, with dramatic cell population changes in specific time windows!

Thanks, Rajini! Feel free to reach out if you take this approach. We have a new Fellow in our group interested in rare skin disorders.

Love it. We have been generating retinal organoids lately, too. Should think about making an assembloid. 🤔

A prenatal skin atlas reveals immune regulation of human skin morphogenesis Nature - A comprehensive multi-omics reference atlas of prenatal human skin shows that innate immune cells crosstalk with non-immune cells to perform pivotal roles in skin morphogenesis, including...

Exciting to see the collection of HCA papers out this week in Nature. Honored to be in the mix with our collaboration with @mhaniffa.bsky.social and Sarah Teichmann on a fetal skin atlas. Bravo to Hudaa, Elena, and Bayanne et al, for pulling this study together. A tremendous effort! rdcu.be/d02Yx

The Human Cell Atlas: towards a first draft atlas In a collection of research articles and related content, the Human Cell Atlas consortium presents tools, data and ideas towards the generation of their first draft atlas of cells in the human body.

A collection published across Nature Portfolio journals presents early draft maps of cells in the human body from the Human Cell Atlas initiative. The research leverages new data and analytical tools to aid our understanding of human health and disease at a cellular level. 🧪
