Menchero et al. generate a single-cell transcriptomic atlas in the opossum and show rapid progression of transcriptional programs in specific tissues relative to morphological landmarks. This shift in...

In vertebrate embryos, somite pairs form on either side of the neural tube along the main body axis. Somites generate the tissues of the musculoskelet…

How does a single egg become a human, and how does this shape our aging? From the earliest heartbeat in embryos to the aging of blood vessels, we’ll explor…

Lebedeva et al. show that unlike Bilateria, the embryo of the cnidarian Nematostella specifies its endomesoderm in the β-catenin-negative domain. In contrast, subsequent β-catenin-dependent axial patt...

Background BMP signaling is responsible for the second body axis patterning in Bilateria and in the bilaterally symmetric members of the bilaterian sister clade Cnidaria—corals and sea anemones. Howev...
