Team finds a better way to grow motor neurons from stem cells

Researchers report they can generate human motor neurons from stem cells much more quickly and efficiently than previous methods allowed. The finding will aid efforts to model human motor neuron development, and to understand and treat spinal cord injuries and motor neuron diseases such as amyotrophic lateral sclerosis.

Analyzing living cells quickly and accurately

In order to investigate inflammation, tumors or stem cells, medical practitioners analyze living cells. Non-invasive optical procedures such as Raman spectroscopy accelerate this procedure. Researchers have now developed it to industrial scale.

To grow or not to grow: a step forward in adult vertebrate tissue regeneration

The reason why some animals can regenerate tissues after severe organ loss or amputation while others, such as humans, cannot renew some structures has always intrigued scientists. In a new study, researchers show, for the first time, that zebrafish regenerates its caudal fin by a process that involves a specific channel in the cell membrane, called V-ATPase, that pumps hydrogen ions, generating an electrical current.

New technique for identifying gene-enhancers

Berkeley Lab researchers led the development of a new technique for identifying gene enhancers - sequences of DNA that act to amplify the expression of a specific gene - in the genomes of humans and other mammals. Called SIF-seq, this new technique complements existing genomic tools, such as ChIP-seq, and offers additional benefits.
