What is the difference between juvenile (C-12210) and adult HDMEC (C-12212)? Which ones should I use for my experiments?

Our juvenile HDMEC (C-12210) are isolated from foreskin of young male donors (1-10 years). In contrast; adult HDMEC (C-12212) are derived from different skin localisations like the cheek; temple; or breast. The donors are > 20 years old and are mostly female. Adult HDMEC are the cells of choice when you need cells from a particular part of the body (other than foreskin); or if it is important for your study to use cells from female and/or adult donors.
