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 half of our genomes consists of thousands of remnants of ancient viral DNA, known as transposable elements, which are widespread across the tree of life. Once dismissed as the 'dark side' of the ...

Researchers at Karolinska Institutet have mapped how small RNA molecules, such as the recently Nobel Prize-awarded microRNAs, control cell development in the human embryo during the first days after ...

To better understand the effectiveness of infertility treatment, it is necessary to study the processes that occur during the first week of embryonic development. At this stage, the embryo begins to ...

Chimpanzee naive pluripotent stem cells (PSCs) can now be grown in cellular cultures, reveals a recent study. They successfully created chimpanzee early embryo models, called 'blastoids,' and found ...

A new study using stem cell-based models has shed new light on how the human embryo begins to develop, which could one day benefit the development of fertility treatment. The study led by at the ...

Early embryonic development is tumultuous. It involves a rapid sequence of events, including cell division, differentiation, and lots of compartments moving around within each cell. Like an orchestra ...

Research led by the University of Cambridge Loke Center for Trophoblast Research has shown that a genome-editing technique ...

A new review from Genes and Diseases sheds light on the pivotal role of LINE-1 elements in preimplantation development and totipotency, revealing their essential contributions to early mammalian ...

This allows researchers to use guinea pigs to investigate how early environmental changes, such as exposure to various chemicals or drugs, can affect embryo development and future health. "Guinea pigs ...
