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.
The exact cause of velamentous cord insertion is unknown, although risk factors include nulliparity, [2] [6] the use of assisted reproductive technology, [6] [12] maternal obesity, [6] [7] and pregnancy with other placental anomalies. [9] Velamentous cord insertion is often diagnosed using an abdominal ultrasound.
Parietal epithelial cell (PEC) Podocyte; Angioblast → Endothelial cell; Mesangial cell. Intraglomerular; Extraglomerular; Juxtaglomerular cell; Macula densa cell; Stromal cell → Interstitial cell → Telocytes; Kidney proximal tubule brush border cell; Kidney distal tubule cell; Connecting tubule cells; α-intercalated cell; β-intercalated ...
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 ...
Cellular extensions of certain mural cells possess the capability to regulate the diameter of their associated blood vessels. Through the processes of vasoconstriction and vasodilation, these cells can actively control the rate of blood flow by means of:
The spinal cord forms from the lower part of the neural tube. The wall of the neural tube consists of neuroepithelial cells, which differentiate into neuroblasts, forming the mantle layer (the gray matter). Nerve fibers emerge from these neuroblasts to form the marginal layer (the white matter).
A cell that is specified can have its commitment reversed while the determined state is irreversible. [3] There are two main types of specification: autonomous and conditional. A cell specified autonomously will develop into a specific fate based upon cytoplasmic determinants with no regard to the environment the cell is in.
The marginal nucleus of spinal cord, posteromarginal nucleus, or spinal lamina 1 (Rexed lamina 1) is located at the most dorsal aspect of the posterior grey column of the spinal cord. The neurons located here receive input primarily from Lissauer's tract and relay information related to pain and temperature sensation.
