25) Zebrafish, Danio rerio
Zebrafish can be found in the tropical fresh waters of northern India, northern Pakistan, Nepal, and South Asia. They can grow up to 4-5 centimeters in length and get their name from stripes on their body (Hamel & Mercier). Zebrafish also have the remarkable ability of liver regeneration.
After the liver in the Zebrafish has lost hepatocytes from sort of injury, biliary cells have been found to migrate to wound site. The biliary cells dedifferentiate through a process that was initiated by Notch signaling, which in turn activated cholangiocytes to dedifferentiate the cells (He et al.). Once the cells dedifferentiated, they would proliferate and re-differentiate into hepatocytes. The hepatocytes would then attach to the liver and gradually increase the liverÕs size. Once the liver is at its maximum size the biliary cells would stop dedifferentiated and disperse back to where it came from.
