Lonza is offering different dermal cell types, which are either isolated from adult or from neonatal tissue.

Lonza’s adult dermal cells (including keratinocytes, microvascular endothelial cells, fibroblasts, and melanocytes) are usually isolated from skin tissue obtained through elective/cosmetic surgeries. Most adult dermal cells are isolated from abdominal skin tissue obtained through abdominoplasties [also known as “tummy tucks”]. Occasionally, alternate skin tissues are used (including, but not limited to breast skin tissue obtained through mastopexies [also known as “breast lifts”] and thigh skin tissue obtained through “thigh lifts”). Occasionally (but rarely) Lonza may also obtain skin tissue from cadavers.

Lonza’s neonatal dermal cells (including keratinocytes, microvascular endothelial cells, fibroblasts, and melanocytes) are isolated from foreskin tissue obtained through neonatal circumcisions.
