What are stem cells? An easy to understand introduction

introduction to stem cells

Most of us have heard about stem cells. Research in this field is very promising, though the use of stem cells is also plagued by controversy.

What are stem cells anyway?

Basically, stem cells are cells that have the potential to develop into different types of cells (e.g. blood cells, heart cells, brain cells). They also have the ability to divide indefinitely to replace cells that are worn out during the lifetime of the person (or animal) due to diseases, age or injuries. The new cells can remain as stem cells or develop into other types of specialized cells.

The video below offers a short (only three minutes long) and easy to understand primer on stem cells.
