Researchers have developed a new embryo-like model derived from adult cells that replicates key features of early human development, including the generation of blood cells. University of Pittsburgh ...

Despite being an essential developmental process, the understanding of human embryonic genome activation is limited, owing to the lack of in vitro cell models and ethical concerns. To advance ...

The curved shape of a zebrafish egg causes unequal cell divisions, creating larger cells near the animal pole and smaller ...

Life begins with a single fertilized cell that gradually transforms into a multicellular organism. This process requires ...

When you seek the help of a fertility specialist to conceive, your first step is to undergo diagnostic tests to understand your likelihood of success. This is followed by a comprehensive consultation ...

Long before human bone marrow takes over the task of producing blood, discrete waves of blood cell production occur in the developing embryo. Miriana Dardano, a postdoctoral researcher in Zweigerdt’s ...

Under the microscope, MSK scientists studied how cells in a mouse embryo (green) move out and break away from their original tissue by contracting their surfaces (red). Studying this process, known as ...

Many scientists today work in a laboratory environment designed to study the small things. Micropipette in hand, researchers slave for weeks, months, or years over a few microliters of solution that ...

In April, researchers in China reported that they had initiated pregnancies in monkeys through a procedure seemingly much like in vitro fertilization (IVF), in which embryos created in a dish were ...
