Getting it over the finish line was a labor of love—and now, more than five years after her death, the lab of former Sloan ...

In the earliest stages of life, mammalian embryos start as a disorganized cluster of cells. As development progresses, these cells become organized into well-defined shapes and structures. This ...

Like all complex organisms, every human originates from a single cell that multiplies through countless cell divisions. Thousands of cells coordinate, move and exert mechanical forces on each other as ...

Two separate research teams used base editing to make single-nucleotide changes in human embryos this month, targeting genes ...

What if you could precisely change the genome of a pre-implantation human embryo and then safely use that embryo to try to ...

Using CRISPR-based engineering methods to prompt stem cells to organize into embryo-like structures, scientists were able to create 'programmable' cellular models of embryos without ever experimenting ...

Scientists have uncovered a surprising new way that giant embryonic cells divide—without relying on the classic “purse-string” ring long thought essential for splitting a cell in two. Studying ...

Most people have heard of stem cells. They are often described as “miracle” cells –ones that can grow into any other type of cell in our bodies, promising revolutionary medical treatments. However, ...

Much was promised in the late 1990s, but the challenge of advances such as growing whole human organs has been difficult to deliver, writes Simon Roach ...
