Cord lining Cord lining Cord lining, cord tissue, 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).

Umbilical cord prolapse Umbilical cord prolapse Umbilical cord prolapse is when, during labor, the umbilical cord comes out of the uterus with or before the presenting part of the baby. The concern with cord prolapse is that pressure on the cord from the baby will compromising blood flow to the baby. The greatest risk factor is having had more than two previous children with the current baby in an abnormally positioned within the uterus. Other risks include a premature or small baby, twin pregnancy, and too much amniotic fluid. Whether medical rupture of the amniotic sac is a risk is controversial. The diagnosis
