Keratinocytes

PRIMACYT is one of the pioneers in the development of advanced in vitro model systems. We are a leading company in the field of research of human and animal hepatocytes.

In 2008, we have received the Research Prize of the German Ministry of Nutrition, Agriculture and Consumer Protection for the “Development and validation of a serum-free, standardized and re-usable human hepatocyte culture system for the analysis of food, drugs and chemicals”.

PRIMACYT is approved by the European Commission as an EU Reference Laboratory for Alternatives to Animal Testing (EURL ECVAM) since 2013 and serves as a member of the laboratory network responsible for the method validation. 

Our colleagues are professionals and undergo continuous training in the preparation, isolation, and cryopreservation of hepatocytes in general, including related co-products, methods, and tools. We are a GLP certified laboratory since 2006.

Currently under construction.

PRIMACYT is a provider of human keratinocytes from juvenile skin. Our human epidermal keratinocytes are available from single donors, isolated from the juvenile foreskin. Culturing non-adult cells is mostly preferred for a variety of studies in cell research.

Cryopreserved normal human epidermal keratinocytes will be shipped on dry ice and should be stored at -80° C or below. Each vial contains more than 500.000 viable cells after thawing.

The cells are tested for morphology, cell viability, and adherence rate. Growth performance is tested through multiple passages up to at least 15 population doublings. Immuno-histochemical staining of keratinocyte specific antigen Cytokeratin 14/16/17 is performed for human keratinocytes.

PRIMACYT also provides researchers with proliferating cell cultures that are made from cryopreserved cells, which have been thawed and cultured at PRIMACYT. Growth performance is tested through multiple passages up 16 population doublings. 

Ethical Compliance:
Human tissue donations are obtained with the inform consent from donors who undergo surgery. The tissue is removed during surgical operations and would otherwise be discarded as biological waste.
