CTIBIOTECH develops and produces human cell-based bioassays, i.e. predictive models of human tissues and cells for biomedical, pharmaceutical and dermatocosmetic research and development

CTIPharma™ open innovation (model development) and services (contract testing) activities to support drug development, biologics, medical device in oncology, immuno-oncology & regenerative medicine.

CTISkin™ open innovation (model development) and services (contract testing) activities to support your skin biology safety & efficacy evaluation projects.

CTIBiosourcing® manufacturing of human biological models, tissues and cells delivered to your laboratory. More than 50,000 tissues samples in stock or on demand through our network of 200 healthcare partners worldwide.

=> CTISkin™Ex vivo kit. This new product is a standardised and ready-to-use solution for your efficacy and safety tests. Collected immediately after surgery, we provide you with the freshest possible skin biopsies that can be used for up to 11 days all ex vivo skin bioassays.

=> CTISkin™ Single Donor Kit.Provides access to primary human cells from a single donor to support your ethical and regulatory compliant in vitro bioassays with 2 to 6 primary cell types (keratinocytes, fibroblasts, adipocytes, sebocytes, melanocytes, blood cells) from the same donor.

=> CTIMultiSkin.3D Bioprinted Full Human Skin Equivalent have a defined structure with a functional basement membrane separating a dermis (containing fibroblasts) from the epidermis (containing keratinocytes at different levels of maturation/cornification). These skin models are derived from single human donors and can be supplemented with other cell types depending on the model required for the efficacy claim being made for screening the safety and efficacy of ingredients, formulated or finished products, cosmetic or medical devices. For example, the immune system (involved in inflammation or allergies), melanocytes (involved in pigmentation), endothelial cells (skin vascularization) or sebocytes (involved in acne, oily skin, dry skin).
