Areas of the brain vulnerable to neurodegenerative disorders like Alzheimer’s disease tend to have less dense vascular networks — which supply the brain wit
To understand the biological underpinnings of skin and hair pigmentation and related diseases such as albinism or melanoma, scientists and doctors need quantitative, three-dimensional information about the architecture, content and location of pigment cells. Penn State College of Medicine researchers have developed a new technique that allows scientists to visualize every cell containing melanin pigment in 3D, in whole zebrafish.
Melanin is visualized in a silver-stained, 5-day-old zebrafish using X-ray histotomography. The different colors were assigned based on the depth of
