Recreating the adrenal gland in a petri dish
A pink stained microscopic image shows the round structure of adrenal organoids growing together

The structure and function of adrenal gland ‘organoids’ grown in a petri dish at the School of Veterinary Medicine closely replicated that of the human adrenal gland, according to a new study. (Image: Courtesy of the Sasaki laboratory)

Recreating the adrenal gland in a petri dish

A School of Veterinary Medicine–led team coaxed stem cells to take on the characteristics and functions of a human adrenal gland, progress that could lead to new therapies for adrenal insufficiencies and a deeper understanding of the genetics of such disorders.

Making ‘true’ equine IVF a reproducible success

A new method developed by Katrin Hinrichs and colleagues in the School of Veterinary Medicine resulted in the birth of three healthy foals, opening the door to new insights in the basic biology of horse reproduction.

Microbes that cause cavities can form superorganisms able to ‘crawl’ and spread on teeth
Three microscopic images labeled with green and blue show a group of microbes changing shape and moving

In the microbial assemblages, fungal cells (blue) made up the periphery with bacteria (green) in the middle. Fungal hyphae, or elongated filaments, enabled the cluster of microbes to propel itself along the surface of a tooth. (Image: Penn Dental Medicine)

Microbes that cause cavities can form superorganisms able to ‘crawl’ and spread on teeth

These multicellular, cross-kingdom assemblages were more resistant to antimicrobials and removal and caused more extensive tooth decay than their single-species equivalents, according to research led by School of Dental Medicine scientists.

Environment influences coral’s resilience to acidification

Ocean acidification is an effect of climate change that threatens the health of coral. A new study examines how coral samples from the Great Barrier Reef fare in acidic conditions.
