FGF2 and type 2 diabetes mellitus: In addition, we performed co-culture experiments of T2DM ASCs and HVSMCs to further investigate the role of bFGF in T2DM ASC-induced recruitment of HVSMCs.T2DM ASCs previously treated with bFGF formed tube-like structures and HVSMCs localised around ASCs, providing support and stability to the capillary-like structures.
