Building a better brain (model) in the lab
Leica Picture of a brain organoid: courtesy National Institute of Allergy and Infectious Diseases, NIH One of the biggest problems with trying to understand what is happening in a disease that affects the brain is that it’s really difficult to see what is going on inside someone’s head. People tend to object to you trying … Continue reading Building a better brain (model) in the lab
A new stem cell derived tool for studying brain diseases
Sergiu Pasca’s three-dimensional culture makes it possible to watch how three different brain-cell types – oligodendrocytes (green), neurons (magenta) and astrocytes (blue) – interact in a dish as they do in a developing human brain. Courtesy of the Pasca lab Neurological diseases are among the most daunting diagnoses for a patient to receive, because they … Continue reading A new stem cell derived tool for studying brain diseases
Stem cells reveal developmental defects in Huntington’s disease
Three letters—CAG—determine whether a person is healthy or develops Huntington’s disease. HD is a progressive brain disorder that affects movement, cognition, and personality. More than 30,000 Americans have HD, and no treatment can slow the disease. HD stems from a mutation in the huntingtin gene caused by an expanded CAG repeat. People with fewer than … Continue reading Stem cells reveal developmental defects in Huntington’s disease
