Cryopreservation of precision cut tissue slices (PCTS): Investigation of morphology and reactivity
Original language description
Precision cut tissue slices (PCTS) represent a suitable and convenient tool for pharmacological, toxicological and morphological studies. Cryopreservation would enable to overcome the shortage of liver tissue, in particular in settings using human livertissue. We investigated the potential of cryopreservation of porcine PCTS as a morphological tool by rapid freezing with 10% and 30% dimethyl sulfoxide as cryopreservation agents and with or without medium using a Brendel/Vitron tissue slicer. Incubationafter thawing was done in a static incubation system. Slices were cultured for 3 h, 6 h, 24 h and 48 h and assessed histologically and immunohistologically for proliferation (Ki67) and spontaneous as well as induced apoptotic activity (M30Cytodeath). Vitality was tested using the Tox-8 test. After cryopreservation, morphology of PCTS was well preserved up to 24 h. A reduction of vitality rate took place. Compared to non-frozen PCTS, the rate of spontaneous proliferation of Kupffer cells
