Evaluation of fibrosis in precision-cut tissue slices.

1.In this review, the use of precision-cut tissue slices (PCTS) of the liver, kidney, lung and intestine in fibrosis research are evaluated and future possibilities are discussed. 2.In vivo models or techniques that are applicabless to be investigated in PCTS are discussed. 3.It is concluded that the early onset of fibrosis can be induced successfully in PCTS prepared from human and experimental animals. 4.Moreover, precision-cut slices of fibrotic tissue are effective in gaining new knowledge of the mechanisms of fibrosis and of the mode of action of potential antifibrotic drugs. 5.Both healthy and fibrotic human tissue slices will pave the way for the testing of novel therapeutic drugs to treat patients with fibrosis avoiding interspecies extrapolation.
