Exactly, in my lab we work primarily on bone and colon tissue (although generated from adult stem or induced pluripotent stem cells). It would not be exaggerating to call these technologies the next generation of medical research. There are tons of genetic and developmental disorders that are either too rare to study readily in vivo or just impossible to study in-vitro. We're nearing the point where we can start with IPSC's either engineered to carry mutations of interest or derived directly from patients carrying these mutations and turn them into all sorts of tissues: liver, colon, neural, vascular, muscular, etc. In many cases it's not even necessary to get to the stage of organoids, simply having true human tissue with the right pathophysiology will be a tremendous boon to in-vitro drug screening and discovery and far more relevant than animal models.
