Simms, Nathaniel Hauser, Chia-Chi Chuang Key, Charles E. McCall, John S. Parks, Susan Sergeant, Carl D. Langefeld, Aleksander Skardal, Elaheh RahbarHepatocytes cultured in 2D on a layer of collagen began to de-differentiate (i.e., lose their rounded morphology) at around 4 days of culture. Conversely, those that were cultured in the 3D configuration maintained their phenotype for at least 7 days.
