  • Instead of throwing the umbilical cord in the wastebasket, parents will have the opportunity to donate their newborn's cord to a national MSC bank where the cord perivascular cells HUCPVCs will be extracted and cryogenically preserved in nitrogen at -200 degrees for 15 to 20 years.

  • Between the layers are cleft-like spaces which communicate with the subarachnoid cavity, and a number of bloodvessels which are enclosed in perivascular lymphatic sheaths.

  • The inner walls of these perivascular spaces seem likewise covered for a certain distance by the mesothelial cells, reflected with the vessels from the arachnoid covering of these vascular channels as they traverse the subarachnoid spaces.

  • The bloodvessels that enter and leave the brain are surrounded by perivascular channels.

    IX. Neurology. 4h. The Cerebrospinal Fluid

  • Through these perivascular channels there is probably a small amount of fluid flowing from nerve-cell to subarachnoid space.

    IX. Neurology. 4h. The Cerebrospinal Fluid

  • In the perivascular spaces, the pia apparently enters as a mesothelial lining of the outer surface of the space; a variable distance from the exterior these cells become unrecognizable and are apparently lacking, replaced by neuroglia elements.

    IX. Neurology. 4g. The Meninges of the Brain and Medulla Spinalis

  • The chemical differences between the subarachnoid fluid (product of choroid plexuses and perivascular system) and the ventricular fluid (product of choroid plexuses alone) indicate that the products of nerve-metabolism are poured into the subarachnoid space.

  • Under the microscope these tumors showed an increase in the interfascicular as well as perivascular fibers, but the nerve-fibers were not increased in size
