HCEP primary human corneal cells growing in fully defined CnT-PR medium benefit from the presence of PCT factors that aid retention of proliferative progenitors, and reduce differentiation.

The HCEP cells are provided cryopreserved in the fully defind CRYO-Defined culture medium, to maximise recovery after thawing.

The cultures undergo a range of QC tests in our lab before being released for sale, and are also covered by our longevity guarantee. Please see the datasheet for details.

HCEP cells may also be grown in CnT-57 medium if desired. This low-BPE medium can improve attachment and proliferation on standard cell culture plastic for some cell lots. Please enquire for details.

The thawing, seeding and passaging protocols are particularly important for optimal cell growth. Please visit our Protocols Page for our recommendations.

Please visit our publications database and search by tissue type to obtain a range of articles that have used CELLnTEC primary cells and media in this specific field.

Corneal Epithelium Progenitors

Normal human corneal epithelial progenitor cells, cryo preserved at early passage.

This material is of human origin and should therefore be handled as hazardous. Although it has been tested negative for HIV 1, Hepatitis B and Hepatitis C, treat this material as potentially infectious, and use appropriate biocontainment, protective equipment and other precautions to prevent accidental exposure.
