Betterhumans reports on another team working on scaffolds and tissue engineering for damaged hearts. As the team lead says, "through tissue engineering we could actually restore the function of the heart by replacing large portions of the damaged heart muscle by a bioartificial one." Interestingly, this work demonstrates that embryonic stem cells work where adult bone marrow stem cells do not. We need more studies like this to quiet the more sophisticated anti-research groups speaking out against embryonic stem cell research. This research also illustrates that work with scaffolding materials for regenerative medicine is advancing rapidly.
