Placental membranes

Placental membranes: nature's wound coverings

Human placental tissues are structural tissues that feature a collagen-rich matrix, native human growth factors and endogenous placental cells.2

Human placental membrane components

Extracellular matrix (ECM):

  • Collagen
  • Elastin
  • Fibronectin
  • Laminin

Growth factors and other mediators:*

  • EGF
  • bFGF
  • KGF
  • PDGF
  • VEGF
  • TGF-beta 1 and -beta 3
  • HGF
  • NGAL

Cells within structural tissue:

  • Epithelial cells
  • Fibroblasts
  • Other placental cells

S+N Placental Membranes and Tissue Processing

Most human tissue products use processes that do not retain all three components of native placental tissue. S+N proprietary tissue cryopreservation and lyopreservation processes have been shown to retain all native components of human placental tissue.1
