Amniotic tissue in modern care
What the innermost layer of the placenta is being used for — and why.
Last updated: July 2026
Amniotic membrane is the innermost layer of the placenta — a thin, avascular tissue made up of a basement membrane and stromal matrix. Recovered as part of a healthy, consented birth (rather than from a deceased donor, as with most other allograft tissue), it’s processed into a patch-like graft such as AmnioBioGraft.
Published literature documents amniotic membrane allografts in use across wound care, orthopedic and spine procedures, foot and ankle surgery, dermatology, ophthalmology, and oral surgery. In wound applications specifically, researchers attribute its effect to a combination of natural tissue planes, anti-inflammatory properties, and support for re-epithelialization and angiogenesis — the biological processes underlying wound closure.
As with any allograft, the specific clinical outcome depends on the case, the surgeon, and the product — the summary above reflects general findings from published research on the tissue type, not a claim about a specific outcome for any Suarez Biotec product.
