New method precisely locates gene activity and proteins across tissues

Posted by in category: biotech/medical

A new method can illuminate the identities and activities of cells throughout an organ or a tumor at unprecedented resolution, according to a study co-led by researchers at Weill Cornell Medicine, NewYork-Presbyterian and the New York Genome Center.

The method, described Jan. 2 in a paper in Nature Biotechnology, records gene activity patterns and the presence of key proteins in across , while retaining information about the cells’ precise locations. This enables the creation of complex, data-rich “maps” of organs, including diseased organs and tumors, which could be widely useful in basic and .

“This technology is exciting because it allows us to map the spatial organization of tissues, including cell types, cell activities and cell-to-cell interactions, as never before,” said study co-senior author Dr. Dan Landau, an associate professor of medicine in the Division of Hematology and Medical Oncology and a member of the Sandra and Edward Meyer Cancer Center at Weill Cornell Medicine and a core faculty member at the New York Genome Center.
