The overloading of free radicals overtime may cause irreversible and lead to diseases and cancers. The zebrafish is an important and widely used vertebrate model.

ROS-mediated autophagy was involved in cancer cell death induced by novel copperII complex.

. As a consequence of injury resident skin cells eg keratinocytes macrophages dendritic cells and mast cells are exposed to danger signals which in general can be divided into two categories. A germ cell is any biological cell that gives rise to the gametes of an organism that reproduces sexuallyIn many animals the germ cells originate in the primitive streak and migrate via the gut of an embryo to the developing gonadsThere they undergo meiosis followed by cellular differentiation into mature gametes either eggs or spermUnlike animals plants do not have. Therapy involving somatic stem cells is not controversial.

A damage-associate molecular patterns DAMPs ie molecules released by stress cells undergoing necrosis such as the intracellular proteins DNA and RNA. DNA Chromosomesand Genomes 195 5. However the metabolism of oxygen may produce unstable molecules or free radicals which causing damage to DNA and other structures including cellular protein and lipids.

Thus free radicals have been linked to a variety of diseases and antioxidants can. Isolation of some types could cause considerable tissue or organ damage as in the heart or brain. Somatic stem cells can be transplanted from donor to patient but without drugs that suppress the immune system a patients immune system will recognize transplanted cells as foreign and attack them.

The zebrafish Danio rerio is a freshwater fish belonging to the minnow family of the order CypriniformesNative to South Asia it is a popular aquarium fish frequently sold under the trade name zebra danio and thus often called a tropical fish although both tropical and subtropicalIt is also found in private ponds.
