For the generation of the human skin-derived precursors (hSKP) spheroids, ultra-low attachment 96-well plates, cell-repellent (Greiner) are used. hSKP cultured on tissue culture plates are detached with trypple (5 minutes) and collected in a tube. After centrifugation, hSKP are counted at the Burker

Drug-induced phospholipidosis (DIPL) is a metabolic disorder characterized by an excessive intracellular accumulation of phospholipids caused by cationic drugs. Hepatic cells derived from human skin are evaluated as an in vitro model to investigate DIPL and its mechanisms. Human skin stem cells

ATP transports chemical energy within cells by serving as a substrate for kinases and as such fulfills a vital function in numerous cellular processes such as cell injury and subsequent cell death. ATP is therefore a crucial player in these events that are results of intracellular stress.
