  1. Tissue Engineering of the Heart By: Dan Tamayo

  2. Problem Being Solved • Regenerate heart tissues that have been damaged by Myocardial Infarction • Help those with heart failure • End the need for a heart transplant list

  3. History of Tissue Engineering • 1897-thoughts of growing cells were being discussed • 1907- the first cells were grown outside of a living body • 1940’s- the ability to specifically grow certain cells was discovered • 1970’s- first artificial pancreas was made • Mid 1990’s- starting to use direct tissue delivery to the affected area • 1998- the development of stem cells really broadened the tissue engineering possibilities

  4. History Continued • 2001-President Bush restricts the funding for stem cell research • Mid 2000’s- FDA approves most cells grafting into human bodies • 2009-Obama lifts the ban on federal funding for stem cell research.

  5. State of the Art Technology • Today, scientists have been able to use the extracellular matrix from pig or rat hearts to make a new one using a technique called decellularization. • In 2011, Columbia University’s Biomedical Engineering researchers developed a new way to patch a heart.

  6. This is the process of decellularization and recellularization. • Decellularization is when all the cells are removed except for the extracellular matrix (top) • Recellularization is when the new cells are grow in and around the new heart scaffold (bottom)

  7. Tissue Scaffolds Empty Scaffold Scaffold with cultured heart cells from a rat

  8. Limitations • Small chance of immunorejection • Cost • Research

  9. Future • Optimal scaffold for cardiac tissue will be found • Ability to re-grow a heart from your cells to be transplanted into your body
