Elucidating the developmental origin of life-sustaining adrenal glands
microscopic image with proteins labeled in red and blue shows tissue that develops into the adrenal glands

The adrenal glands, which pump out crucial hormones, develops differently in mice compared to primates, including humans, according to new research led by the School of Veterinary Medicine. At at early stage of development, the primate adrenogenic coelomic epithelium, which eventually gives rise to the adrenal glands, expresses genes (NR5A1 in red, and GATA1 in blue) in a pattern that diverged with expectations.

Frozen testicular tissue still viable after 20 years

Many pediatric cancer treatments, though lifesaving, can compromise future fertility. In a new study in rodents, researchers from the School of Veterinary Medicine showed that testicular tissue frozen for more than 20 years could give rise to sperm.

In the Galápagos, training community scientists to monitor water quality

Both dense human populations and a plethora of wildlife can pose a challenge to marine and public health in the Galápagos Islands. With portable, user-friendly PCR technology, Penn faculty and students are training local scientists and school children to perform water quality research.

Correcting night blindness in dogs

Researchers in the School of Veterinary Medicine and colleagues have developed a gene therapy that restores dim-light vision in dogs with a congenital form of night blindness, offering hope for treating a similar condition in people.

Recent research at Penn and elsewhere underscores that SARS-CoV-2 has jumped repeatedly between species during the COVID-19 pandemic. 

SARS-CoV-2 is moving between humans and wildlife around the U.S.

In humans the pandemic is showing signs of ebbing. In white-tailed deer and other wildlife, however, infections appear widespread.
