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

Alkaptonuria (AKU) is a rare inborn error of metabolism caused by a defective homogentisate 1,2-dioxygenase (HGD), an enzyme involved in the tyrosine degradation pathway. Loss of HGD function leads to the accumulation of homogentisic acid (HGA) in connective body tissues in a process called

The purpose of the present development is to use avian MoDCs to implement a cellular platform to increase understanding of the immune responses induced by various antigens of interest (e.g. vaccine candidates) and evaluate their immunogenic potential. Considering the difficulty to work on dendritic

Cultivated liver cells are fixed with 4% (w/v) paraformaldehyde (PFA) for 10 minutes at room temperature and subsequently incubated for 15 minutes with 100 mM glycin solution, used to saturate reactive groups generated after PFA fixation. These cells are subsequently incubated for 10 minutes with 1%

The in vitro micronucleus test is a genotoxicity test for the detection of micronuclei in the cytoplasm of interphase cells and has been described in detail in OECD TG 487. Micronuclei may originate from acentric chromosome fragments (i.e. lacking a centromere), or whole chromosomes that

E. coli is one of the organisms of choice for the production of recombinant proteins. DH5 alpha cells are commonly used for maintenance, propagation and mutation, whilst BL21(DE3) and C43(DE3) are mainly used for expression of the transgene. The advantage of C43(DE3) is that is used to produce

For therapeutic or reporter molecules to be effective for therapy or imaging applications, proper accumulation of the compounds in the tissue of interest is required, with minimal accumulation in undesired organs to avoid toxic side-effects and increase bioavailability. After initial in vitro

The VITOTOX test is a bacterial genotoxicity test. The test is based on bacteria that contain the lux operon of Vibrio fischeri under transcriptional control of the mutated recN promoter, which is controlled by the bacterial SOS-system (TA 104-recN2-4 strain or Genox strain). After incubation

This method uses human skin-derived precursors (hSKP) differentiated towards hepatic cells (hSKP-HPC) as a hepatic in vitro model. Exposure of these cells for 24 hours to sub-cytotoxic concentrations of acetaminophen, which is a reference hepatotoxicant, induced specific cellular responses in a
