In order to improve the investigation of pancreatic cancer (PC), often supported through analyzes two-dimensional (2D) cell monolayers, we proposed to create a spheroid-based in vitro three-dimensional (3D) model using wild-type (WT) and ANXA1 knock-out (KO) MIA PaCa-2 PC cells. The gene discussed is ANXA1; the disease is pachyonychia congenita.
