About

The growth medium from cultured sheep skin cells, subject to EU animal by-product restrictions due to concerns over transmissible spongiform encephalopathies.

Sheep fibroblast conditioned media carries a specific EU Annex II/419 reference warning under Regulation 1223/2009. This entry restricts animal-derived materials classified as Category 1 or 2 under Regulation (EC) No 1069/2009, which includes tissues with potential BSE/TSE risk. Fibroblasts from sheep present a theoretical prion transmission risk, making EU compliance complex and requiring sourcing from TSE-free certified animals with full traceability documentation.

Skin benefits

Known concerns

  • EU Annex II/419 animal by-product restriction
  • BSE/TSE risk from ovine tissue requires TSE-free certification
