 This MLM for 3D co-culturing creates adipospheres appropriate for WAT modeling ex vivo and provides a new platform for functional screens to identify molecules bioactive toward individual adipose cell populations.It can also be adopted for WAT transplantation applications and aid other approaches to WAT-based cell therapy.Using the MagPen™ (a Nano3D Biosciences, Inc. product), organized 3D co-cultures similar to native tissue architecture can be rapidly created.
