But the type of a cell is determined by patterns of expression of that genome. The cell’s nature is shaped by which proteins ...

In a lab in Japan, scientists transformed cells from the tails of male mice into eggs. They fertilized the eggs with ordinary ...

DNA analysis is crucial for identifying individuals and their relatives, using technologies like PCR, electrophoresis, and fingerprinting.

The success of in vitro fertilization depends on many factors, one of which is sperm viability. A recent study from the ...

They use CRISPR-based engineering methods to prompt stem cells to organize into "programmable" embryo-like structures, also known as embryoids, which can be used to study the role of certain genes in ...

Just because a sperm is a strong swimmer doesn't necessarily mean it has the right amount of DNA, Dr. Lisa Lee told Newsweek.

"These cells co-develop together, just like they would in an actual embryo, and establish that history of being neighbors," ...

Scientists have found a way to study early embryonic development without real embryos. Using CRISPR, they programmed stem cells to self-organize into structures mimicking early embryos. The cells show ...

Primordial germ cells, the founder cells of the germ line, are set aside in the early animal embryo, and divide and differentiate to produce sperm and egg, the male and female gametes. While ...
