Aided by stem cells, a lizard regenerates a perfect tail for the first time in 250 million years

Lizards can regrow severed tails, making them the closest relative to humans that can regenerate a lost appendage. But in lieu of the original tail that includes a spinal column and nerves, the replacement structure is an imperfect cartilage tube. Now, for the first time, a USC-led study in Nature Communications describes how stem cells ...

Skeletal muscle grown in a dish offers new insight for neuromuscular diseases

Neuromuscular diseases are debilitating and mostly incurable, affecting 160 out of every 100,000 people worldwide. Disorders such as ALS and multiple sclerosis impact the function of muscles, causing muscle wastage and loss of motor function. A major hurdle in the fight against these diseases is the fact it is notoriously difficult to grow tissue in ...

USC-led study traces the blueprints for how human kidneys form their filtering units

When it comes to building a kidney, only nature possesses the complete set of blueprints. But a USC-led team of scientists has managed to borrow some of nature’s pages through a comprehensive analysis of how kidneys form their filtering units, known as nephrons. Published in the journal Developmental Cell, the study from Andy McMahon’s lab ...

Study of skull birth defect takes it from the top

Contrary to the popular song, the neck bone is actually connected to one of 22 separate head bones that make up the human skull. These plate-like bones intersect at specialized joints called sutures, which normally allow the skull to expand as the brain grows, but are absent in children with a birth defect called craniosynostosis. ...

USC Stem Cell scientists explore the latent regenerative potential of the inner ear

Scientists from the USC Stem Cell laboratory of Neil Segil have identified a natural barrier to the regeneration of the inner ear’s sensory cells, which are lost in hearing and balance disorders. Overcoming this barrier may be a first step in returning inner ear cells to a newborn-like state that’s primed for regeneration, as described ...

Study highlights differences in immune cell function between male and female mice

A new USC study of a common, yet poorly understood type of white blood cell reveals the human immune cell’s response to pathogens differs greatly by sex and by age.  In this mouse study, males proved much more susceptible to a condition called sepsis than females. However, the scientists also found that the female disease-defense system is hardly perfect; their system changes with age to become nearly as harmful as the males’.    Those are the key findings in a study that appeared July 19, 2021 in Nature Aging.   ...

USC Professor Scott E. Fraser redefines impossible problems

USC Professor Scott E. Fraser is known for inventing new microscopes and other tools to observe living, developing embryos. But one of his lab’s most important pieces of technology filters coffee instead of light: it’s a restaurant-quality Espresso machine. “I wanted to make a place where people would come to steal coffee,” he said. “And ...

USC Stem Cell study points to a common ancestor for cells involved in hearing and touch

The sensory cells in the inner ear and the touch receptors in the skin actually have a lot in common, according to a new study from the USC Stem Cell laboratory of Neil Segil published in the Proceedings of the National Academy of the Sciences (PNAS). “There are striking similarities in the development of two ...

USC Professor Megan McCain crafts an approach to tissue engineering

Megan McCain has always liked using her hands to create things, ranging from art projects to human heart cells that grow on silicon chips. “I’ve always loved building things and doing crafts, which drew me to engineering,” said McCain, who was recently awarded tenure as an Associate Professor and the Chonette Early Career Chair in ...
