Summary
ABSTRACT Understanding the transcriptional programs governing cell identity and function is key to many outstanding questions in biology and biomedicine. Most variants associated with common diseases and traits lie in non- coding, regulatory regions of the genome, and to interpret their function, we need to identify the genes they affect and how those are expressed in the different cells of a tissue within individuals, and quantify how their expression varies across individuals. How these mechanisms are regulated during human development remains poorly understood, and most studies to date have
