Will MSC micropellets outperform single cells for cartilage regeneration?

Repair of cartilage injuries or defects is aided by the introduction of mesenchymal stem cells (MSCs), which can be incorporated into hydrogels to amplify their effects. In a new report, researchers directly compared chondrogenic induction by hydrogels that were prepared using MSCs either as single cell suspensions or as 100-500-cell micropellets. The study is published in Tissue Engineering.
