## Regenerating the Heart
* Overview of stem cell applications in cardiovascular disease (CVD).

## Understanding Stem Cells
* Stem cells serve as raw materials for specialized cells.
* Focus on their ability to differentiate into cardiomyocytes to repair damaged heart tissue.

## The Global Burden of CVD
* CVDs are the leading cause of death globally.
* Ischemic Heart Disease accounts for approximately 8.9 million deaths annually.

## Mechanisms of Action
* **Direct Differentiation:** Creating new heart and vascular cells.
* **Paracrine Signaling:** Secreting growth factors for healing.
* **Angiogenesis:** Forming new blood vessels.
* **Immune Modulation:** Reducing inflammation and scarring.

## Key Stem Cell Types
* **Mesenchymal Stem Cells (MSCs):** Derived from bone marrow/adipose tissue; known for safety.
* **Induced Pluripotent Stem Cells (iPSCs):** Reprogrammed adult cells; patient-specific to reduce rejection.

## Delivery Challenges
* Up to 90% of injected cells can be washed away by blood flow.
* Solutions include hydrogel scaffolds and cardiac patches to improve cell retention.

## Clinical Trial Landscape
* Active clinical trials by cell source:
    * Bone Marrow MSCs: 45%
    * Adipose MSCs: 25%
    * Cardiac Stem Cells: 20%
    * iPSCs: 10%

## Future & Summary
* Shift from simple injections to 3D bioengineered scaffolds.
* Potential for iPSCs to mitigate rejection and arrhythmia risks.
