An international team of scientists led from Sweden's Karolinska Institutet has for the first time mapped all the genes that are activated in the first few days of a fertilized human egg. The study, ...

In the earliest hours after fertilization, an embryo takes its first steps toward becoming a living organism by shedding maternal control and activating its own genetic program. This critical process, ...

Over the past few decades, growing evidence has challenged the belief that inheritance is governed solely by DNA sequences. Scientists now recognise the crucial role of epigenetic inheritance – the ...

Humans have around 30 trillion cells in our adult bodies. Amazingly, each of these cells came from a handful of about 100 ...

Yu Leqian, a professor at the Institute of Zoology under the Chinese Academy of Sciences and head of the human embryo model ...

Scientists found that embryonic skin cells “whisper” through faint mechanical tugs, using the same force-sensing proteins that make our ears ultrasensitive. By syncing these micro-movements, the cells ...

Developmentally expressed genes play a fundamental role in the formation of a wide range of organs. The Y chromosome-located mammalian sex-determining gene Sry, required for the formation of testis, ...
