Final answer:
Embryonic stem cells have the potential to cure cellular disorders like Parkinson's disease, but there are obstacles and ethical considerations to address.
Step-by-step explanation:
Embryonic stem cells have the potential to help cure cellular disorders like Parkinson's disease. Stem cells are capable of dividing and differentiating into specialized cells, making them a potential treatment option for diseases such as diabetes and heart disease.
However, there are obstacles to overcome in the application of cell-based therapy, as embryonic stem cells can be seen as foreign by the patient's immune system and may trigger rejection. Additionally, the destruction of embryos to isolate embryonic stem cells raises ethical and legal questions.
