Multimedia project update

For those of you who have submitted your multimedia projects, thank you!  I am willing to extend your deadline to Friday. If your project is ready for submission tomorrow, I will accept it. The deadline is extended to Friday. 

Tomorrow's lecture will be on Cancer Stem Cell and will be included in your quiz on Friday. After lecture  I will give you a little bit of time to take photos of your AP stain lab today. If we run out of time, you will need to come in during lunch to do the pictures and microscope viewing. 

I will need hard copies of all projects unless it is a video. You will also need to submit an electronic version to me the day before submission.

You may also choose to do an recorded advertisement and upload the video to YouTube. Please email me the link. The video can include "actors" or based solely on something you create on the computer using slides and voice-overs.

Blog assignment update


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.
