Insights into Muscles Formation

An international team of researchers discovers two proteins essential to the development of skeletal muscleAll vertebrates need muscles to function; They are the most abundant tissue in the human body and are integral to movement.

'Tunability' of a Molecular Chaperone

Scientists report that Hsp70s from mammalian cells behave quite differently from bacterial Hsp70s. Because of the important roles Hsp70s play in protein misfolding diseases such as cancer and neurodegenerative diseases, the new findings 'will have a major impact on how we think about Hsp70s,' one of the researchers says. The study appears in  PNAS.

Role Of Schwann Cells In Nerve Regeneration

In Canada, approximately 3% of all traumatic injuries result in nerve damage resulting in many patients suffering from lifelong sensorimotor impairments. In severe cases, patients will undergo nerve repair surgery but this surgery is often delayed for months after the original injury.

This means that at the time of surgery, the injury to the nerve cells has occurred. The study was published in the journal Cell Reports.

Human Skeletal Stem Cells Has Found

If only we could regrow our broken bones like Harry Potter, Skele-gro style. Or, at the very least, heal up like a limb-regenerating newt. Alas, we humans possess no such abilities. Though our bodies cannot break bones, the older we get, the shoddier that patch job gets.

As for cartilage, the crucial cushioning that keeps our bones from rubbing together – once that's gone, it's gone for good. The study was published in Cell.

Hair Cell Regeneration Treatment For Deafness

Researchers have proposed to use an embryonic stem cell as a platform for in vitro. Deafness due to disease, aging, or birth defects is caused by the loss of hair cells in the inner ear, which is the structure responsible for the detection of equilibrium and sound.

Currently, deafness is a progressive and irreversible condition in humans, with the typical treatment to be the use of hearing aids. A treatment for deafness could be on the horizon, as a European study investigates the possibility of inducing regeneration of the inner ear cells.
