Go to On-Line Virtual Stem Cell Laboratory and Do/Answer the Following on Separate sheet of paper. You may turn in one sheet for two people.
1) Define stem cell
2) What are embryonic stem cells?
3) Try the coaxing agents and see what they do. Trace at least 4 pathways to their endpoints. Describe 4 of these pathways.
4) Describe what these 4 endpoints are used for (read the text on the website). For example, motor neuron cells can be used to treat ALS!
Go to Learn Genetics Link and go to Go Go Stem Cell!
1) What is a niche?
2) Go to 3 of the possible stem cell niches and go through the simulation. Describe what happens to the cell as it is converted from a stem cell to its particular differentiated cell.
