Levitating stem cells form blobs

Nathan Jeger-Madiot et al.

Stem cells levitated with sound can spontaneously form spherical blobs. The technique could be used for growing tissues or simple miniature organs without researchers having to physically manipulate cells and potentially disrupting the way they function in the process.

Engineering or creating tissues, like pieces of cartilage for knee repair, is challenging because the chemicals and forces used to coax cells into the desired shape can make them not function normally once inside a person. Mauricio Hoyos at the French National Centre for Scientific Research …
