Lecture 13, 3/26/15Paper Review
3D gels for ischemia
What is the motivation of this study?
• Much of current cell therapy relies on dosing cells at the site – many of which are lost during delivery.
• One mechanism to improve cell therapy is to encapsulate cells into a biomaterial – keeping the cells alive during the harsh delivery.
• The authors propose to deliver adipose(fat)-derived mesenchymal stem cells in very small injectable gels to protect them during delivery.

Conclusions, Perspectives
• By encapsulating cells in 3D microniches, they could use a dose more than 10 times lower than previous cell based therapies.
• Accumulation of ECM and paracrine signaling in the niches likely provided survival signals to cells.
• Priming was a key step to improving MSC differentiation prior to delivery.
