First 'cell map' of 20,000 cells in mammalian embryo

Scientists at the Wellcome—MRC Cambridge Stem Cell Institute have used cutting-edge technology to profile over 20,000 individual cells to produce the first 'cell map' describing all the major cell types present at the early ...

Team reveals rules for making ribs

Scientists from the USC Stem Cell lab of Francesca Mariani recently shared a recipe for ribs, and it doesn't even require barbecue sauce.

Reconstructing life at its beginning, cell by cell

The eyes have it

Our bodies, with all their different features and variations, are the result of well-orchestrated processes that dictate what and how cells develop into the organs and tissues that comprise our anatomy. Much of the information ...

Repetitive elements shape embryonic chromatin landscape

Retrotransposons are repetitive elements that form almost half of the mammalian genome. Even though they are so common, they have previously been considered to be fairly insignificant. Together with colleagues from the USA, ...

Mechanism that impairs production of bovine embryos is revealed

A longstanding obstacle to the market for bovine embryos is lipid accumulation in oocytes. Researchers have now described a hitherto unknown mechanism of lipid accumulation in oocytes that limits the success of in vitro production ...
