Uncovering the clock that sets the speed of embryo development

Why do pregnancies last longer in some species than others? Researchers at the Francis Crick Institute have found the clock that sets the speed of embryonic development and discovered the mechanism is based on how proteins ...

Researchers grow retinal nerve cells in the lab

Johns Hopkins researchers have developed a method to efficiently turn human stem cells into retinal ganglion cells, the type of nerve cells located within the retina that transmit visual signals from the eye to the brain. ...

Study reveals the genetic start-up of a human embryo

An international team of scientists led from Sweden's Karolinska Institutet has for the first time mapped all the genes that are activated in the first few days of a fertilized human egg. The study, which is being published ...

Stem cell technology could lead to ailing heart mending itself

For the first time, scientists can efficiently generate large numbers of rare cells in the network that pushes the heart's chambers to consistently contract. The technique, published May 28 in Stem Cell Reports, could be ...

Lab-grown nerve cells make heart cells throb

Researchers at Johns Hopkins report that a type of lab-grown human nerve cells can partner with heart muscle cells to stimulate contractions. Because the heart-thumping nerve cells were derived from induced pluripotent stem ...
