Abstract
As overweight and obesity rates have increased worldwide, the prevalence of metabolic disorders has also grown. Due to the lack of physiologically relevant adipose tissue platforms, research in adipose tissue biology has relied on animal models, leading to false conclusions on pathophysiological mechanisms and therapeutic efficacy. Despite the urgent need for an adipose tissue model, it is still extremely difficult to cultivate mature adipocytes and recapitulate multi-cellular interactions in adipose tissue in vitro. For this reason, adipose tissue modeling requires new technologies that allow better culture conditions for adipocytes and contain a complex network of microenvironments. Herein, we discuss recent technologies, including 3-dimensional (3D) adipocyte spheroids, biomaterial-based 3D culture, 3D bioprinting, and microphysiological systems, which may offer new opportunities to discover drugs targeting adipose tissue.
