What are pluripotent stem cells?
Pluripotent stem cells are cells that can differentiate into any cell type in the body, making them valuable for research and therapy.
How does external beam radiation therapy work?
It uses targeted radiation to destroy cancer cells while sparing surrounding healthy tissue.
What is a teratoma?
A teratoma is a type of tumor that can contain various types of tissues, such as hair, muscle, and bone.
Why is imaging important in this study?
Imaging allows for precise targeting of tumors and helps plan effective radiation treatments.
What precautions should be taken when working with radiation?
Appropriate shielding and safety protocols must be followed to minimize exposure to radiation.
