cells -cells th the very early embryo candipperentielle and specialise into all of the ce'll types that make up the cell type that make up the individual, they're pluripotent all of the genes in embryonic Stem cells can be expressed to allow these cells to differ- -entiate and specialise into any cell type Research stem cells - under the right conditions, embryonic stem cells can selfrenew in the labatory. this allows Scientists to use them for research purpouses. Stem cells can be used as model cells to study now disease develops TIC Therapeutic +reaserch Uses of Stemcells They provide info on how cellular processes such as cell growth, differentation and gene regulation work. used as modelcells for testing drugs. therapeutic stem cells therapuetic uses involve the Repair of damaged or diseased organs or tissues Do Not talk about diseased or damaged cells, must say organs or tissus. currently used for :- ~Repair of damaged or diseased organs or tissues eg. To repair corneal damage in the eye eg. To replace and regenerate damaged skin Ethnical debate of embryonic stem cells uses for embryonic stem cells can offer effective treatments for disease and injury. important & -However embryonic stem cell use involves the distruction of embayo
