stem cells

Question 1

stem cells

Answer 1

embryonic stem cells are pleuripotent, adult stem cells have plasticity

Question 2

stem cell niche

Answer 2

term used to describe the microenvironment of stem cells. Interacts with stem cells to regulate stem cell fate

Question 3

adult stem cell splasticity

Answer 3

traditionally adult stem cells thought to have limited potential, only renewing tissue from which they are derived. Recent evidence suggests one tissue may transdifferentiate to renew other tissue types

Question 4

reprogramming

Answer 4

adult skin cells have been genetically modded into induced pluripotent stem (iPS) cells. Theraputic potential is large, les ethical concerns, avoids immune rejection (come from individual

Question 5

initiation and maintenance of cancer

Answer 5

emerging data from virtually all cancers suggests cancer may be maintained by a small amount of cancer stem cells resistant to traditional cancer therapies. When you kill off the cancer (radiation or chemotherapy), some resilient cancer stem cells can bring tumor back.
