JCI insight

Ng SS, Xiong A, Nguyen K, Masek M, No DY, Elazar M, Shteyer E, Winters MA, Voedisch A, Shaw K, Rashid ST, Frank CW, Cho NJ, Glenn JS.
PMID: 28570275
JCI Insight. 2017 Jun 02;2(11). doi: 10.1172/jci.insight.90853. eCollection 2017 Jun 02.

A major challenge for studying authentic liver cell function and cell replacement therapies is that primary human hepatocytes rapidly lose their advanced function in conventional, 2-dimensional culture platforms. Here, we describe the fabrication of 3-dimensional hexagonally arrayed lobular human...
