HPEKs primary human epidermal keratinocytes (single donor) growing in CnT-PR medium benefit from the presence of PCT factors that aid retention of proliferative progenitors, and reduce differentiation.

This extends not only the lifepsan of the cells, but importantly also the period during which the cells retain the ability to complete complex processes such as 3D differentiation.

The HPEK 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.

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.

Epidermal Keratinocyte Progenitors, Single Donor

Normal human epidermal keratinocyte progenitor cells, isolated from juvenile donor material, cryo preserved at 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.
