Our special processing and cleansing of the amniotic tissue is very gentle to the tissue, and allows us to preserve the critical wound healing characteristics that are inherent in the amniotic tissue, and this yields an allograft with remarkable healing capabilities. This process does not decellularize the tissue, but rather retains those growth factors and cytokines that are critical to healing."
