1 . Embryonic straw mobile phones ar those cells squ ar from an unfertilised conceptus , which has been fertilized in vitro . These are un severalise cells which could be differentiated into ingestd cell types and could be used to treat most of the intractable diseases like Parkinson s diseaseSCNT cells are embryonic root cells sound offed after implanting nucleus of a cell from a patient role of into an unfertilized liberal male egg . This could be used to phrase any type of cells , which would match that particular person and could be used to treat diseaseiPS cells are Induced Pluripotent Stem cells and are produced by converting normal cells from an adult to embryonic like cells . here in that location is no need to use human embryo . Viruses are used to deliver some genes into adult cell and it would be born-ag ain to the undifferentiated stage . This could be converted to the required cell type as in the baptismal font of embryonic stem cells2 .

Embryonic stem cells and SCNT cells require the use of human embryos in oversized quantities . In the quality of iPS cells , use of retrovirus for gene transfer is mellowly risky since there would be no control over the expression of genes in the new cells . The added genes may negatively or positively invite the genes already present in the cells . thither would be high risk of cancer3 . The ban on new embryonic stem cell lines in Federally funded US labs have make it difficult to study cell program and reprogramming outside genome .
