Cloning

Cloning. 3 Possible Methods. 1. Use totipotent cells (unspecialized) Can become any type of human cell Can be used to generate an entire organism Example: embryonic stem cells 2. Use Pleuripotent cells (partially specialized) Can become same types of cell

  1. Cloning

  2. 3 Possible Methods 1. Use totipotent cells (unspecialized) • Can become any type of human cell • Can be used to generate an entire organism Example: embryonic stem cells 2. Use Pleuripotent cells (partially specialized) • Can become same types of cell • These cells (nuclear material) must be “modified” to allow development Example: Fetal stem cells (4-6 week old fetus) Placental/cord blood stem cells Adult stem cells (bone marrow) 3. Use multipotent cells (specialized cells) Example: skin cells, udder cells

  3. *Totipotent PleuripotentMultipotent Unspecialized Specialized Unfertilized Egg (Enucleated) Stem Cell  Nucleus of unspecialized cell is put in unfertilized egg  Mitosis occurs (must be stimulated by drugs or electric current)

  4. Uses for Cloning • Grow organs to transplant • Treat Genetic Disorders • Agriculture – genetically engineered crops • Bring back endangered species

  5. Clone Mimi the Mouse • Enucleation
