Zebrafish 'able to repair spinal cord injuries'
In a cross section of the adult zebrafish spinal cord, stem cells (green) can be seen to divide (red and/or blue)
In a cross section of the adult zebrafish spinal cord, stem cells (green) can be seen to divide (red and/or blue).

Discovery may offer hope for new therapies in humans
 
Zebrafish are able to heal their own spinal cord injuries by growing new motor neurons, scientists have discovered.

It is hoped this finding could one day lead to new therapies for people with neurodegenerative conditions, such as motor neuron disease.

Damage to motor neurons in humans - either as a result of neurodegeneration or spinal cord injury - is irreversible.

Yet researchers from the University of Edinburgh found that serotonin - best known as the mood boosting hormone - can help zebrafish recover from spinal cord injuries.

They found the hormone is able to send signals to stem cells found in the spinal cord, boosting the growth of new motor neurons.

Using these findings, scientists say they may be able to grow motor neurons in the lab, aiding research into neurodegenerative conditions in humans.

Dr Thomas Becker, from Edinburgh's Centre for Neuroregeneration and the Euan MacDonald Centre for Motor Neuron Disease Research, said: "Understanding how zebrafish are able to repair damaged nerves could one day help us to trigger similar mechanisms in human stem cells.

"Our hope is that this may eventually lead to new treatments for conditions such as motor neuron disease, for which there is no cure."

Defra shares new Sanitary and Phytosanitary guidance

News Story 1
 Defra has published guidance for the vet sector ahead of a proposed UK-EU Sanitary and Phytosanitary agreement.

The agreement, which will change the movement and trade of animals and related products, could see reductions in checks, paperwork and certification. As well as describing regulatory developments, the advice highlights the importance of animal ID, registration and traceability in disease control and other compliance arrangements.

The guidance can be found here. More detail is expected as negotiations progress.

New form for online veterinary medicines retailers

The Veterinary Medicines Directorate (VMD) has produced a new online form for retailers wishing to sell veterinary medicines on the internet.

The form replace the previous Word version and is part of the VMD's ongoing commitment to digitise its processes. Anyone retailing prescription medicines online, including POM-V, POM-VPS and NFA-VPS categories, is lawfully required to register with the VMD before trading.

The change only applies to new applicants. Retailers already listed on the VMD's Register of Online Retailers or registered under the Accredited Internet Retailer Scheme (AIRS) do not need to do anything.
