Transcript of Natural Regeneration

Natural Regeneration by: Patrick Mao What Is Natural Regeneration? Urodeles Amphibians (Vertebrates) Salamanders, Newts, Chameleons, Frogs, Tadpoles The only vertebrates able to regenerate Differentiation Shedding (Autotomy) Geckos, Skinks, Lizards, and Slamanders Octopuses, Crabs, Brittle Stars, Lobsters, and Spiders Reptiles + Salamanders Invertebrates Stem Cells Unspecialized Able to divide and renew Can form specialized cell Replaces missing cells from damaged areas Cardiovascular Disease / Heart Disease, Mend the Heart Applications Type 1 Diabetes, Produce Insulin Parkinson's Disease, Dopamine-Producing Brain Cells More research needed, to make more safe, and to make more efficient Muscular Dystrophy, Skeletal / Muscular Repair Hearing / Vision Embryonic Stem Cells Adult Stem Cells Become: Red Blood Cells White Blood Cells Skin Cells Bone / Cartilage Cells Fat Cells Nerve Cells Embryonic Stem Cells: Embryonic and Adult Stem Cells Adult Stem Cells: Active during Embryo stage (Preimplatation) Active throughout whole life Made in Vitro Fertilization Found among differentiated cells in tissues and organs You can call them "Backup" Cells Through more research / experiments, they can be used to cure diseases Both: Differentiate into specialized cells Asexual Reproduction Echinoderms and Worms Fissiparity and Fragmentation Achitomy, Paratomy, and Budding Discovery of RNA Images Cited Works Cited Roy, Stephanie.
