Stem Cells and Regenerative Medicine.pptx

This is a well-organized and illustrated presentation about the role of stem cells in regenerative medicine. It includes an explanation of stem cells, in what fields they are used, and specific examples of medical procedures directly involving them.

1. Stem Cells in Regenerative Medicine Ryan Han

2. Why are stem cells important in this field? Stem cells are used to replace or support damaged cells, modulate repair, and build tissues This shifts care from long-term management toward restoration and potential cures.

3. Examples of how stem cells are used: Stem cells are harvested either from the patient’s own body, or taken from external source Nurtured into desired cells Transplanted into desired region Mesenchymal Stem Cells (MSCs) release secretomes to surrounding cells in areas of tissue damage Reduces inflammation, encourages cell growth Specialists inject secretomes into region Medical professionals create a biomedical scaffold Stem cells are put into place, encouraged to grow Put into damaged region Cell Replacement Paracrine Signaling Tissue Engineering

4. Different types of stem cells Induced Pluripotent Stem Cells Adult Stem Cells Embryonic Stem Cells Derived from the inner cell mass of early-stage embryos Pluripotent, meaning they can develop into any of the body's specialized cell types Undifferentiated cells found in various body tissues Multipotent, can self-renew and differentiate into specific cell types of their native tissue to maintain and repair it a type of stem cell created from other adult cells, like skin or blood, through reprogramming. Once reprogrammed, these iPSCs become pluripotent, meaning they can develop into any type of cell in the body, similar to embryonic stem cells.

5. Current and future of regenerative medicine: Current uses: Hematopoietic stem cell transplants Diseased or damaged blood-forming cells are replaced with healthy ones to treat blood disorders and cancers Retinal cell implants Dysfunctional photoreceptor cells are replaced with electronic chips that convert light into electrical signals Cartilage transplants Damaged cartilage is replaced with healthy cartilage stem cells to stimulate repair of damaged region Future impacts: Could shift towards a more permanent cure instead of constant, temporary treatment for some patients Could save money in the long term Specialized technology and teams needed for future improvements

6. Conclusions Stem cells are important because they enable replacement, modulation, and engineered tissues; they can transform medicine from management to repair; Many fields of regenerative medicine requires it, yet steps need to be taken to ensure it is used accurately and safely
