Why does researchers prefer to use embryonic stem cells instead of adult stem cells?

Researchers prefer embryonic stem cells because they are pluripotent, meaning they can differentiate into any cell type in the body, providing greater versatility for regenerative medicine. In contrast, adult stem cells are usually multipotent, limited to differentiating into a narrower range of cell types. Additionally, embryonic stem cells have a longer lifespan in culture and can be more easily manipulated genetically, making them valuable for research and potential therapeutic applications. However, ethical concerns surrounding the use of embryonic stem cells often influence their use in research.
