IL1B and type 2 diabetes mellitus: The goals of the research studies presented in this paper were to (a) characterize the stemness properties of IPFP-ASCs isolated from non-diabetic (Non-T2D), pre-diabetic (Pre-T2D), and diabetic (T2D) patients and (b) determine the levels of expression of inflammatory mediators and adipokines in IL-1B stimulated IPFP-ASCs and adipocytes and in a co-culture system with monocyte-derived macrophages.
