Stem cells are really interesting!

They are special cells in our bodies that can change into different types of cells. This changing process is called differentiation.

You can think of stem cells like blank pages in a notebook or seeds that can grow into different kinds of plants.

There are two main types of stem cells:

1. Embryonic Stem Cells:

   • These come from embryos.
   • They can turn into any type of cell in our body.
   • For example, they can become muscle cells, nerve cells, or even blood cells!

2. Adult Stem Cells:

   • These are found in places like bone marrow.
   • They have a more limited job.
   • Their main role is to replace damaged cells.
   • For instance, blood stem cells in the bone marrow can change into different types of blood cells, like red blood cells that carry oxygen.

Stem cells are very important!

They have huge potential in medicine. They can help treat diseases like leukemia or injuries to the spinal cord.

By learning how they change into other cells, scientists are getting closer to using them to heal many conditions!
