2. Discuss stem cell therapy as a method of regenerating areas of injury that normally would be replaced by scar tissue, such as the brain or heart. What is the current status of research in this area?

3. Discuss somatic cell reprogramming with transcription factors and microRNA for cardiac tissue regeneration in animals.
