Abstract
In vitro cell culture serves as an efficient system for studying animal cell behavior in a controlled setting. Here, we present a 3D culture model for forming ruminant adipose organoids using stromal vascular fraction cells. We describe steps for forming cell spheroids and growing them on a Matrigel-coated surface. We then detail procedures for inducing organoids to undergo angiogenesis and adipogenesis followed by capillary sprouting. This protocol can be utilized to study the interaction between blood vessels and adipocytes. For complete details on the use and execution of this protocol, please refer to Yu et al.1.
