Cell that make up the inner cell mass of the blastocyst are pluripotent, and can give rise to any cell in the body, but cannot give rise to the cells of the placenta Adult stem cells are multipotent and can give rise to multiple specialized cell types present in a specific tissue or organs Human induced pluripotent stem (iPS) cell lines are usually generated by artificial dedifferentiation of differentiated human cells, such as skin cells Embryonic stem cells can be harvested from the patient, edited and then redelivered back to the patient In using embryonic stem cells, there is the possibility of an immune reaction and rejection, as embryonic stem cells are not patient specific

Stem cells differ from other kinds of cells in the body. All stem cells, regardless of their source, have three general properties: they are capable of dividing and renewing themselves for long periods; they are unspecialized; and they can give rise to specialized cell types. Embryonic stem cells, as their name suggests, are derived from embryos. Specifically, embryonic stem cells are derived from embryos that develop from eggs that have been fertilized in vitro at an in vitro fertilization clinic and then donated for research purposes with informed consent of the donors. They are not derived from eggs fertilized in a woman's body. Regarding human stem cell therapy, scientists are developing a number of strategies for producing dopamine neurons from human stem cells in the laboratory for transplantation into humans with Parkinson's disease. The successful generation of an unlimited supply of dopamine neurons could make neurotransplantation widely available for people who have Parkinson's at some point in the future. Using the above information, describe two societal and two technological obstacles that researchers have to overcome in their quest to find a cure for Parkinson's disease.

stem cells are a type of cell that have yet to become specialized. This means that their role within the body has not been determined yet. Due to this unique property, stem cells are able to become cell or regenerate (regrow) damaged tissue. Evaluate what positive impact stem cells could have on the future of the human population.
