Histopathological analysis of human biopsies. To quantitatively characterize the transition from simple STEA to eNASH, we stained, imaged and digitally reconstructed human liver tissue in 2D and 3D from biopsies of 25 patients classified into four groups: normal control (NC, n = 6), healthy obese (HO, n = 4), steatosis (STEA, n = 8) and eNASH (n = 7).

Liver Systems Medicine : striving to develop non-invasive methods for diagnosing and treating NAFLD by combining mathematical modeling and biological research. LiSyM, is a multidisciplinary research network, in which molecular and cell biologists, clinical researchers, pharmacologists and experts in mathematical modeling examine the liver in its entirety. LiSyM research focuses on the metabolic liver disease non-alcoholic fatty liver disease (NAFLD), which includes non-alcoholic steatohepatitis ...

One of the tasks of the healthy liver is to store fat. Yet, at some stage, too much fat makes the liver sick. One critical time point occurs when a healthy fatty liver becomes inflamed and progresses to steatohepatitis, or NASH. LiSyM-Pillar I will identify what events lead to this transition. Does it occur in all parts of the liver? Which molecules indicate that it is taking place? Can the degeneration be stopped or undone - and if so, how?

Experimental assay Human-NAFLD/NC 6 biopsies from normal control patients. : NC samples showed steatosis ≤5%, no inflammation, no ballooning and no fibrosis and were obtained during liver resections or biopsy in non-hepatobiliary malignancy in patients with a BMI<30kg/m2. Livers were either free of metastases or a distance of at least 2 cm to the next metastasis observed.
