The umbilical cord lining is a good source of mesenchymal and epithelial stem cells. Umbilical cord mesenchymal stem cells (UC-MSC) have been used clinically to treat osteoarthritis, autoimmune diseases, and multiple other conditions. Their advantages include a better harvesting, and multiplication, and immunosuppressive properties that define ...
Velamentous cord insertion; Other names: Velamentous Placenta: Normal umbilical cord insertion and velamentous umbilical cord insertion in pregnancy, with and without vasa previa. Specialty: Obstetrics Symptoms: Blood vessel compression, [1] [2] decrease in blood supply to the fetus, [2] [3] impaired growth and development of the fetus. [4] [5 ...

The newborn, with normal APGAR scores and umbilical cord arterial pH levels, was admitted to the neonatal intensive care unit. Upon examining the placenta after delivery, it was noted that the placenta demonstrated the appearance of a circumvallate placenta, and also showed evidence of abnormal umbilical cord insertion into the placenta.
The umbilical arteries surround the urinary bladder and then carry all the deoxygenated blood out of the fetus through the umbilical cord. Inside the placenta, the umbilical arteries connect with each other at a distance of approximately 5 mm from the cord insertion in what is called the Hyrtl anastomosis. [1]
Through the processes of vasoconstriction and vasodilation, these cells can actively control the rate of blood flow by means of: Contraction of cellular processes that encircle capillaries as in pericytes, which possess contractile proteins such as α-actin , tropomyosin , and myosin enabling them to contract and relax.
The apex of the posterior grey column, one of the three grey columns of the spinal cord, is capped by a V-shaped or crescentic mass of translucent, gelatinous neuroglia, termed the substantia gelatinosa of Rolando (or SGR) (or gelatinous substance of posterior horn of spinal cord), which contains both neuroglia cells, and small neurons.
Cajal–Retzius cells were described to migrate tangentially in the marginal zone, a superficial layer of the preplate in the cortical neuroepithelium, [3] [4] According to some studies, this migration depends on the site where the cell was generated, showing a link between the origin, the migration and the destination of the cell.
