Mouse Brain Atlas

Our Arpiar Saunders has published his atlas of the mouse brain. Using single-cell sequencing, our lab unmasked the unique genetic signatures of more than 560 cell populations across nine brain regions. Here's an article about the trials and tribulations of creating the study, as well as its implications for scientific research.

Clonal Hematopoiesis and Its Origins

Giulio Genovese has published a follow-up article to his initial discovery of a common precancerous condition. In 2014, we described a common pre-cancerous state, involving the clonal amplification of blood cells with somatic mutations, that is readily detected by DNA sequencing, is increasingly common as people age, and is associated with increased risk of blood cancer later in life. Now, we describe the inherited and acquired mutations that drive this precancerous condition.

Christina Usher Interviewed by the BBC

Christina Usher was interviewed by the BBC for an upcoming special, "The Truth About Carbs". The interview covered what we currently know about the amylase gene and its impact on metabolism. See Christina's paper in Nature Genetics on amylase, from her Ph.D. work in the lab.

Fenna Krienen in Science

An article on the Science website describes Fenna's research to map the brain – first cataloging long-range synaptic connections in the human brain (in Randy Buckner's lab) and now analyzing the conservation of neuronal types and subtypes across species (in our lab).

Schizophrenia and the Complement Proteins

The work of our Aswin Sekar et al. implicate excessive complement activity in the development of schizophrenia and may help explain the reduced numbers of synapses in the brains of individuals with schizophrenia. For more information, check out: An article in Harvard Magazine, featuring an image of C4 protein at synapses, which was taken by our Heather de Rivera; An article in the New Yorker; An article in the New York Times

TP53 Mutations in Stem Cells

Articles by Stat News and GEN on our discovery (together with Kevin Eggan's lab) that pluripotent stem cells routinely acquire dominant-negative mutations in the TP53 gene.  Florian Merkle and Sulagna (Dia) Ghosh led the research team.


Our Evan Macosko has published his work on Drop-seq, a technology we developed to enable massively parallel analysis of RNA expression in thousands of individual cells.

Investigations into DNA Replication Timing

Amnon Koren has published three papers centered around his work on DNA replication timing. He described a new way to study DNA replication by using increasingly abundant whole genome sequence data, which he found contained signatures of DNA replication processes that were active in cells at the moment DNA was extracted from them.
