Synthetic stem cells to regenerate heart tissue

Would you trust science enough to allow them to put synthetic stem cells into your body, organs or even your heart? That's just what American and Chinese researchers have developed. There has been great success with STEM cells but what about synthetic cells, well the scientists have shown that with synthetic cells they can pass immune rejection and tumor growth. They also can't amplify themselves so there is no similar risk as there is with STEM cell transplant.

Key Takeaways:

• American and Chinese researchers have developed synthetic cardiac stem cells that could have the same therapeutic impact as human stem cells, with the added benefit of reducing the risk of graft rejection in cellular therapy.
• The cells they inject are obtained from 'pluripotent' cells, which can give rise to every other cell type, or 'multi-potent' cells that can only give rise to limited number of cell types, both of which are sourced either from donors or patients themselves.
• In concrete terms, the medical team fabricated cell-mimicking micro-particles from PLGA, a biodegradable and biocompatible polymer, and then loaded them with human growth factor proteins before coating them with a human cardiac stem cell membrane. The resulting cells promoted the growth of cardiac muscle in vitro.
