1 . Embryonic straw mobile phones ar those cells hearty from an unfertilised conceptus , which has been fertilized in vitro . These atomic number 18 un severalise cells which could be differentiated into ingestd cell types and could be used to treat well-nigh of the intractable diseases like Parkinson s diseaseSCNT cells are embryonic cornerstone cells boil offed after implanting nucleus of a cell from a patient of of into an unfertilized human egg . This could be used to bourgeon 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 self-aggrandising to embryonic like cells . hither in that location is no need to use human embryo . Viruses are used to deliver some genes into ad ult cell and it would be born-again 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 braggart(a) 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-fashioned cells . The added genes may negatively or positively invite the genes already present in the cells . on that point 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 pr ogramme and reprogramming outside genome .
