Cord lining Cord lining, or umbilical cord lining membrane, is the outermost layer of the umbilical cord. As the umbilical cord itself is an extension of the placenta, the umbilical cord lining membrane is an extension of the amniotic membrane covering the placenta. The umbilical cord lining membrane comprises two layers: the amniotic (or epithelial) layer and the sub-amniotic (or mesenchymal) layer. The umbilical cord lining membrane is a rich source of two strains of stem cells: epithelial stem cells (from the amniotic layer) and mesenchymal stem cells (from the sub-amniotic layer). == Cross-section of the umbilical cord ==
