Over 70 million people worldwide suffer from vitiligo, an autoimmune disorder and in the occurrence your CD8+ T cells attack the melanocytes in the skin causing white patches to appear. Cod liver oil has been used before to study bone regeneration as well as tissue regeneration. This study investigates the effect of cod liver on zebrafish regeneration. Zebrafish is an ideal model organism for studying skin diseases because their melanocytes are extremely similar to ones in humans and has been used before to study other skin diseases. In this study there is one control group and 2 experimental groups. The control group will remain untreated as the baseline for the study. Experimental group 1 will treat the fish with cod liver oil and have their stripes removed with neocuproine. Experimental group 2 will just have their stripes removed and left untreated. This study will take a total of 16 days and microscopic evidence will be taken.
