Abstract: The creation of vascularized adipose tissues is a subject of broad fundamental and technological interest in implantable breast manufacturing. Here, we demonstrated a simple, easy, and effective way to fabricate a spindle hierarchical poly (DL-lactic-co-glycolic acid) (PLGA) encapsulated adipose-derived stem cell (ADSC)/collagen/alginate construct with a multiple-branched vascular network using a rotational combined mould system (RCMS). Both the optimized PLGA overcoat and internal collagen/alginate hydrogel provided the ADSCs with a stable and comfortable accommodation to grow, proliferate, and differentiate. Cell viability remained at a comparatively high level during 4 weeks in vitro engagement with two groups of cell growth factor combinations. At the end of the second week, part of the cells were engaged into endothelial cells, while at the end of the fourth week more than 63% of the ADSCs were replaced by adipose cells. We envisage that this RCMS, vascularization and adipogenesis techniques will provide an enabling platform for a wide array of research and clinical applications.
