An amniotic membrane, the innermost layer of the foetal membrane, is harvested from a woman's placenta for transplantation.
The innermost layer of the fetal membrane, known as the amniotic membrane, is removed from a woman's placenta and harvested for use as a transplant material in reconstructive surgery for conditions like severely burned skin, trauma wounds, chronic wounds, and others. Initially, skin grafts were constructed using an amniotic membrane as a substrate (skin transplantation surgery). Amniotic membranes can also be utilized for a range of procedures, including ocular surgery, aesthetic surgery, cancer treatment, and regenerative medicine, according to the National Center for Biotechnology Information (NCBI). Due to its non-immunogenicity, anti-scarring, antibacterial, and anti-inflammatory properties, the use of an amniotic membrane is advocated.
The placenta's innermost
layer, known as the Amniotic Membrane or amnion, is made up of
a thick foundation membrane and an avascular stromal matrix. In several
surgical subspecialties, amniotic membrane transplantation has been employed as
a graft or a dressing. The Amniotic Membrane separates mother and
fetus while also enclosing and guarding the growing fetus in pregnancy.
The amniotic membrane,
which is the innermost, avascular layer of fetal membranes and is made up of
the epithelium, basement membrane, and stroma, is taken from placental tissue
from a full-term pregnancy and given antimicrobial treatment before being taken
out.
Amniotic
Membrane can serve as a temporary
graft or a replacement for the basement membrane in the eye. Its
anti-inflammatory and anti-scarring properties as well as the growth factors it
contains help the surface of the eye's epithelium heal from wounds. In a
variety of clinical scenarios, such as acute burns, enduring epithelial
abnormalities of the cornea, and conditions that result in conjunctival
scarring, AMT has been demonstrated to be an effective substitute for corneal
and conjunctival repair. AMT has, however, only been the subject of a small
number of randomized, controlled experiments. Other research has demonstrated
that AM can be used as a growth substrate to grow epithelial progenitor cells
for use in reconstructing the ocular surface.
