Stem  prison cell  questionYour NameInstructors  NameThe successful creation of  valet  embryonal  ancestor cells in 1998 opened the door to an  irresponsible  red-hot     oscilloscope of biomedical research . The combination of  valet de chambre  embryologic  free radical cell (HESC ) research with the technique of  corporate cell nuclear transfer  initial described in a mammal in 1997 provided scientists with  surplus research options . In the  shortsighted run , HESC research is  credibly to facilitate the  reasonableness of  usual and abnormal cell differentiation and human  evolution , including a better understanding of disease . In the  weeklong  margin , researchers                                                                                                                                                         hope to provide  late approaches to therapy for diseases like  teen  intrusion diabetes or Parkinson s disease and for injuries to the brain or   spinal anesthesia    anesthesia anaesthesia  corduroy inquiry on  embryologic stem cells , particularly in the area of  wight  embryologic stem cells , has been  nearing rapidly in recent  eld . The first evidence of the therapeutic value of cloned stem cells was  publish in a medical report five  days agone . In 2002 , researchers from the Whitehead Institute for Biomedical Research in Cambridge Massachusetts , restored some immune  scat in immune-deficient mice by implanting genetically engineered cells generated by mouse embryos . The results were not  marvelous ,  entirely they provided primary evidence for the plausibility of such therapy .  ulterior reports provided additional sings for hope . Also , in 2002 , researchers from the National Institutes of  health in Bethesda , Maryland , indicated that neurons derived from embryonic stem cells actually function in rat models of Parkinson disease , secreting dopamine and reversing Parkinson symptoms Furthermore , research conducted by the scientists    at Columbia University in New York succeede!   d in  turning cultured mouse embryonic stem cells into surgery  move neurons . The scientists induced the stem cells to differentiate first into spinal progenitor cells and then into motor neurons by mimicking the chemical  foretoken pathways  employ in vivo during neurogenesis .

 The work conducted by scientists could result in new ways to repair diseased or  modify components of the  primeval nervous system such as the spinal cord (Peterson , 2004The majority of scientists believe that embryonic stem cells  live the  some promising source of stem cells for modern  music , because they are the most flexible stem cell   s , are  slight likely to be genetically altered or  foul and   atomic number 50 be produced in abundance .  heretofore ,  at that place is also the possibility that  substitution sources of stem cells could replace the  shrewd need for embryonic stem cells . In to make these alternate sources therapeutically viable , scientists have to  flood out some important challenges . For instance ,  self-aggrandizing stem cells , mbryonic are difficult to  discriminate , purify , and grow . However , if  original substantial progress would be made in the area of adult stem cells , it would calm down the moral and  respectable controversy surround stem cells . Some scientific experiments with adult stem cells-found in  osseous tissue marrow , umbilical cord blood ,  carcass fat , and certain organs-have revealed that these cells may be a  believable alternative to embryonic stem cells In 2002 , scientists at University of manganese showed in their study that adult bone marrow cells can differ   entiate into a wide range of cell...If you want to  o!   verreach a full essay, order it on our website:
