Embryonic stem cells and adult stem cells are really interesting, and they have some important differences.

1. Where They Come From:

   • Embryonic stem cells are taken from very early embryos.
   • Adult stem cells are found in grown-up tissues, like bone marrow or fat.

2. What They Can Do:

   • Embryonic stem cells are special because they can turn into almost any type of cell in the body.
   • Adult stem cells are more restricted and can only change into certain types of cells that are related to where they are found.

3. How Long They Last:

   • Embryonic stem cells can keep growing in the lab forever.
   • Adult stem cells don’t last as long and have a shorter life span.

Knowing these differences is really important for understanding stem cell research and treatments!
