X-ray studies can help scientists understand the role of melanin in human skin pigmentation and skin cancer
Researchers have developed a new technique that can image every pigment cell of the entire zebrafish in a 3D image
Melanin is a natural pigment that can bring color to the skin, hair and eyes of humans and animals
But directly studying melanin with a traditional microscope is a challenge because melanin blocks light
To perform imaging, Cheng worked with Dula Parkinson, a staff scientist at Berkeley Labs Advanced Light Source (ALS), to image two sets of zebrafish samples-a set of related zebrafish-specific black stripes.
In order to visually observe melanin, lead author Spencer R.
Micro-CT is similar to a human CT scan, but its scale is much smaller.
Researchers say that their silver staining technique can be used to learn more about the 3D structure of melanoma and may guide treatment decisions
