Stem Cells and Cloning Stem cells have a variety of unique properties .To be more specific , all stem cells have three general properties:they are capable of dividing and renewing themselves ; they are unspecialized; and they can give rise to specialized cell types. Adult and Embryonic stem cells are similar but, they are also vastly different.One major difference between adult and embryonic stem cells is their different abilities in the number and type of differentiated cell types they can become.Embryonic Stem Cells can become all different cell types of the body and Adult stem cells are commonly thought to be limited to becoming into different types of cells of their specific tissue of origin. The body is full of adult stem cells and embryonic stem cells.The current sources of adult stem cells are the heart, bones ,and spine.The current sources of Embryonic stem cells is the umbilical cord and the placenta. The potential uses of human stem cells in biomedical research could be to find out trends , diseases,and treatments.They might also use stem cells for testing out new drugs and medicine. Doctors/medicine might use stem cells to apply cures and/or treatment to their patient. There are many challenges facing stem cell research.To be more specific some challenges facing stem cell research are proving long term stability of cells , understanding cell cycle control , building scientific capacity , and understanding cell specialization.
There are many alternate methods by which scientists harvest stem cells.One method is extracting stem cells from the umbilical cord and or bone marrow then they might be used to treat patients with diseases that need cell replacement.Another method is altered nuclear transfer . Some people
