Abstract
In this unit, previously described methods are expanded upon, where procedures relating to the preparation, culturing, and osteogenic differentiation of scaffold-free mouse adipose-derived stromal cell microtissue spheroids (ASC-MT) are outlined. Not only is a detailed methodology of how to engineer such spheroids are presented, but a full account of how to induce and analyze osteogenesis in these ASC-MT constructs is given along with relevant figures to help better illustrate the methods described.
