91) Japanese rice fish, Oryzias latipes

Japanese rice fish or Medakas can be found near Southeast Asia in ponds, streams or rice paddies (Luna). They can range in size from 2- 4 centimeters long (Luna). Medakas have the ability to regenerate their kidney if it was to get damaged.

Soon after the kidney has sustained injury it will undergo some cell apoptosis in the tubular epithelia and glomeruli (Watanabe et al.). This causes the epithelial basement membrane to be stripped of its cells, while cysts form on the glomular and tubular segments. Signals are then sent for the epithelial cells to start proliferating near the wounded site. This helps repopulate the basement membrane and other structures in the kidney. After this occurs a de novo neogenesis phase occurs that will mature the structures in the kidney (Watanabe et al.). The basophilic epithelium cells proliferate and form the renal vesicles, S-shaped tubules, and tubular outgrowths to fuse with the collecting duct (Watanabe et al.). The BowmanÕs capsule is then made from the epithelial cells that have proliferated and matured. When all of the structures in the kidney have regenerated to their maximum size the cells will stop proliferating and disperse away from the previously wounded site.
