Unlike less versatile muscle or nerve cells, embryonic stem cells are by definition equipped to assume any cellular role. Scientists call this flexibility "pluripotency," meaning that as an organism develops, stem cells must ...

The basics of conception are familiar to any high school freshman biology student, yet scientists have yet to find the initial molecular mechanisms that set off the cascade of events that form a developing embryo.

I've often wondered what happens between the time an egg is fertilized and the time the ball of cells that it becomes nestles into the uterine lining. It's a period that we know very little about, a black box of developmental ...

In developing vertebrates, the brain and spinal cord originate from an embryonic structure known as the neural tube. This initially forms as a flat 'neural plate', which subsequently folds around and closes up to form a tubular ...

The factors that shape the destiny of a cell, like that of a fully formed person, remain something of a mystery. Why, for example, does one stem cell in a human embryo become a neuron rather than a muscle cell? And why does ...
