Amnion is placental tissue that surrounds and protects the fetus during development in utero. The properties of amnion that benefit the fetus also make it an effective material for protecting a wide variety of wounds, while at the same time creating an environment conductive to the regeneration of of healthy tissue. Repurposing this versatile tissue to improve outcomes in wound management is supported by studies in published literature which describes its successful and safe clinical use.

Amnio consist primarily of fibrillar and membranous collagens, elastin, and a mix of cytokines and growth factors that provide the properties unique to placental tissues.

  • Placental donors go through rigorous pre-screening qualification
  • Placental donors are tested to confirm they are free from disease
  • Processed in accordance with the safety guidelines provided by the U.S. Food and Drug Administration (FDA) – Human Cellular and Tissue based Products (HCT/P) (21 CFR Part 1271)
