3D technique brings hope for lung regeneration

3D technique brings hope for lung regeneration
New York, March 8: In a ground-breaking discovery, scientists have created 3D techniques that can regenerate lungs from human stem cells.

Daniel Weiss, a professor of medicine at the University of Vermont, has developed lung tissue bioengineering technique that involves scaffold - or framework - of lungs from human corpse to engineer new lungs for patients with end-stage lung diseases.
They examined several perspectives on the process of stripping the cellular material from these lungs - called decellularising - and replacing it with stem cells (recellularisation) in an effort to grow new, healthy lungs for transplantation.
"It’s expensive and difficult to repopulate an entire human lung at one time. Unlike in mouse models, this does not readily allow the study of multiple conditions, such as cell types, growth factors and environmental influences like mechanical stretch - normal breathing motions - that will all affect successful lung recellularisation," Weiss said.

To address this, Darcy Wagner, a post-doctoral fellow working in Weiss’ lab, developed a technique to dissect out and recellularise multiple, small segments in a manner that would take into consideration the appropriate three-dimensional interaction of blood vessels with the lung's airways and air sacs.
With the help of another novel technique - thermography or thermal imaging - Wagner and colleagues developed a non-invasive and non-destructive means for monitoring the lung scaffolds’ integrity and physiologic attributes in real-time during the decellularisation process.
According to Wagner, this method could be used as a first step in evaluating whether lungs and eventual scaffolds are suitable for recellularisation and transplantation.
The study appeared in the journal Biomaterials.

    1. A study investigating an inherited form of Alzheimer’s has found that the progression of the disease may slow once symptoms appear and do significant damage. In the research, Professor Colin Masters from the Florey Institute of Neuroscience and Mental Health and University of Melbourne – and colleagues in the UK and US – have found rapid neuronal damage begins 10 to 20 years before symptoms appear.
    ‘As part of this research we have observed other changes in the brain that occur when symptoms begin to appear. There is actually a slowing of the neurodegeneration,’ Professor Masters said. Autosomal-dominant Alzheimer’s affects families with a genetic mutation, predisposing them to the crippling disease. These families provide crucial insight into the development of Alzheimer’s because they can be identified years before symptoms develop. The information gleaned from this group will also influence treatment offered to those living with the more common age-related version. Only about one percent of those with Alzheimer’s have the genetic type of the disease. The study is published in the prestigious journal Science Translational Medicine.

What is Alzheimer’s Disease?
Alzheimer’s disease is a degenerative mental disease and the most common form of dementia. It results in loss of cognitive function beyond normal ageing and is usually seen in people who are older than 65. Symptoms include confusion, mood swings, long-term memory loss and a gradual loss of bodily functions. This is caused due to plaque deposition in the brain’s neurons which affects its functioning and causes them to die.
