Stem cells in human embryos commit to specialization surprisingly early

The point when human embryonic stem cells irreversibly commit to becoming specialised has been identified by researchers at the Francis Crick Institute

22-Apr-2020

Our biological history can be traced back to a small group of cells called embryonic stem cells, which through cell division, give rise to cells that specialise to perform a specific role in the body - a process known as differentiation. Understanding when and how embryonic stem cells specialise ...

Diversity in the brain

How millions of neurons become unique

27-Sep-2018

How is it possible that so many different and highly specific neurons arise in the brain? A mathematic model developed by researchers from the University of Basel’s Biozentrum demonstrates that different variants of genes enable such a random diversity. The scientists describe in “Cell Reports” ...

Lab-grown neurons improve breathing in mice after spinal cord injury

08-Jun-2018

Researchers from Drexel University College of Medicine and the University of Texas at Austin improved respiratory function in rodents with spinal cord injuries after successfully transplanting a special class of neural cells, called V2a interneurons. Their results indicate that these lab-grown ...

Functioning kidney tissue created

14-Feb-2018

Scientists have successfully produced human kidney tissue within a living organism which is able to produce urine, a first for medical science. The study led by Professors Sue Kimber and Adrian Woolf from The University of Manchester, signifies a significant milestone in the development of ...

(Re)-acquiring the potential to become everything

20-Dec-2017

A new study identifies a specific population of pluripotent embryonic stem cells that can reprogram to totipotent-like cells in culture. Moreover, the scientists of Helmholtz Zentrum München and Ludwig-Maximilians-Universität München (LMU) have identified bottlenecks and drivers of this ...

Bacteria may help babies' digestive tracts more than suspected, scientists find

09-Nov-2017

Some of the first living things to greet a newborn baby do a lot more than coo or cuddle. In fact, they may actually help the little one's digestive system prepare for a lifetime of fighting off dangerous germs. But these living things aren't parents, grandparents or siblings - they're helpful ...

Advance furthers stem cells for use in drug discovery, cell therapy

17-Jul-2017

Since highly versatile human stem cells were discovered at the University of Wisconsin-Madison nearly 20 years ago, their path to the market and clinic has been slowed by a range of complications. Both embryonic stem cells and induced pluripotent stem cells are valued for their ability to form ...

Small RNA fragments defend the genome when it's 'naked'

03-Jul-2017

Our genomes are minefields, studded with potentially damaging DNA sequences over which hundreds of thousands of sentries stand guard. These sentries, called epigenetic marks, attach to the double helix at such spots and prevent the underlying DNA sequences from springing into destructive ...

A nanofiber matrix for healing

15-Feb-2017

A new nanofiber-on-microfiber matrix could help produce more and better quality stem cells for disease treatment and regenerative therapies. A matrix made of gelatin nanofibers on a synthetic polymer microfiber mesh may provide a better way to culture large quantities of healthy human stem ...

TET proteins drive early neurogenesis

12-Dec-2016

The fate of stem cells is determined by series of choices that sequentially narrow their available options until stem cells' offspring have found their station and purpose in the body. Their decisions are guided in part by TET proteins rewriting the epigenome, the regulatory layer of chemical ...
