Treating damaged corneas with stem cells

Posted 3 weeks 5 days ago

Researchers have developed a new way to identify and sort stem cells that may one day allow clinicians to restore vision to people with damaged corneas using the patient's own eye tissue:

The cornea is a transparent layer of tissue covering the front of the eye, and its health is maintained by a group of cells called limbal stem cells. But when these cells are damaged by trauma or disease, the cornea loses its ability to self-repair.

"Damage to the limbus, which is where the clear part of the eye meets the white part of the eye, can cause the cornea to break down very rapidly...

Associate professor of biochemistry and molecular biology Paula Lemons conducts research that aims to improve science education across the nation while helping students at UGA develop independence, teamwork and problem solving skills:

When did you come to UGA and what brought you here?

In 2007, during a transition in my career, I met Peggy Brickman, Josiah Meigs Distinguished Teaching Professor of Plant Biology, at a conference. She told me that UGA might be hiring a new biology education researcher. I said, “Great! Let me know what happens!” I thought I would never hear from...

Great news from NASA for students and faculty working diligently to design and build UGA's first satellite:

The University of Georgia CubeSat project is among 34 small satellites selected by NASA to fly as auxiliary payloads aboard missions planned to launch in 2018, 2019 and 2020.

The UGA project, led by a team of undergraduate students and including faculty from the Franklin College of Arts and Sciences and the College of Engineering, performs multispectral analysis from low Earth orbit, in this case an altitude of 400 kilometers.

"When our project was selected in...

‘Atmospheric rivers’ also common in the Southeast

Some timely and informative new research from geography faculty and graduate students on aspects of the erratic weather seen recently:

Much of the flood-inducing rainfall that has pummeled California over the last month flowed into the region via a river in the sky. But these so-called atmospheric rivers, which transport large quantities of water vapor poleward from the tropics, can wreak havoc in the Southeast as well.

University of Georgia geography and atmospheric sciences researchers provide the first detailed climatological analysis of Southeastern atmospheric rivers in...

The Evolution of Parenting

Genetics researchers share a new study that builds on 50 years of theorizing by behavioralists - how parenting changes parents:

The study, published this month in Nature Communications, finds that the transition from a non-parenting state to a parenting state reflects differences in neuropeptides generally associated with mating, feeding, aggression and increased social tolerance.

Neuropeptides are small proteins that allow neurons in the brain to communicate with each other; they also influence behavior.

The team's research-tested on an insect, the burying beetle...
