As I am reading through some of the posts on the Stem Cell blog, I realize that there is some misunderstanding and/or confusion about Adult Stem Cells vs. iPSCs (Induced Pluriopotent Stem Cells). Adult stem cells are "multipotent", which means that it has limited ability to self renew and differentiate. Adult stem cells exist in various tissues in your body already.
IPSCs, however, are derived from adult SOMATIC cells (terminally differentiated cells). IPSCs do not naturally exist in the tissues in your body. They are instead, "induced" or forced to become pluriopotent. Therefore, there is a possibility that they retain SOMATIC MEMORY (this is because they were once SOMATIC or mature cells).
Adult STEM cells were never SOMATIC CELLS. Therefore, they cannot retain SOMATIC MEMORY.
I hope this clears up any confusion.

NO Quiz on Wednesday!
Multimedia Project Updates
1) For groups who are interested in doing a BLOG for the multimedia group project, you will need only 10 posts/reply from your peers and 2 post from faculty at GHS.
2) Students may also present their ad in the form of a commercial (recorded as a video) and then uploaded to YouTube.
Please check back over the weekend for further information and your lab protocol.

Tuesday Nov. 4
- agreement/disagreement and why? What reference will support your opinion?
- something interesting that you read about online or from a reliable source related to the topic of discussion
- Pose questions that you have about the topic of discussion
- Give an accurate testimonial about your own experience related to the topic of discussion.
Wednesday Nov. 5 / Thursday Nov. 6
Friday Nov. 7 - Some additional resources
2. "Inside the Cell" background information and review of cell from NIH
You can download the FULL PDF file or click on each chapter of the book. Remember that this information is about the 'CELL' not neccessarily about STEM CELLS. But it is a very helpful summary of Biology.
3. Chromosome Spread Lab
