In this week’s Medical Discovery News with UTMB’s David Niesel and Norbert Herzog: Today, scientists are using a certain animal more extensively in order to understand human disease. The Zebrafish is a small torpedo-shaped fish native to the Indian subcontinent. While it looks nothing like a human, this fish is actually a great model for studying aspects of human disease. Its genome has been completely sequenced, it matures quickly, its genes can be manipulated and its embryos are transparent. These characteristics make the Zebrafish a highly used and valuable model for genetic and developmental studies.
