Intravenous Injection of Mesenchymal Stem Cell Spheroids Improves the Pulmonary Delivery and Prolongs In Vivo Survival

Murine adipose-derived MSC line m17.ASC was cultured in agarose-based microwell plates to obtain size-controlled m17.ASC spheroids of an average diameter and cell number of approximately 170 μm and 1100 cells/spheroid, respectively.
