Introduction

Everywhere in the news today you here the word "Stem Cell", it appears in the news of science, medicine, politics, religion, ethics, law and just recently in the 2012 Nobel Prize.

What are "stem cells" and why do they appear to be so important?

Teacher Note
This is currently only a draft designed to help K12 students understand comparative embryology. I am currently looking to simplify concepts and include images on this page. I am happy to receive feedback as too what you may like to be included here. I have also begun to add some simple exercises that can be used in class to help understand concepts on stem cells. Note some of the links on this page leave the K12 notes section and may be beyond the level of your students, bookmark this page to easily return here. This page can be printed using the lefthand menu "Toolbox" or Printable version. --Mark Hill 09:25, 11 October 2012 (EST)
