The Development of Cerebro-spinal Fluid Pathway in Human Embryos

Osaka K. Matsumoto S. and Yasuda M.

Abstract

The early development of the subarachnoid space, the choroid plexus, and the arachnoid villi was studied in 60 normal human embryos ranging from Carnegie stage 12 to 23. The embryos were fixed in Bouin's fluid, paraffin-embedded, serially sectioned and stained with hematoxylin-eosin and Azan. One abnormal human embryo with exencephaly and myeloschisis in the high cervical cord was added for the study. A primitive subarachnoid space (future subarachnoid space) is first distinguishable as cavity formation within the meninx primitiva in the areas ventral to the middle brain vesicle at stage 14. The development of the primitive subarachnoid space precedes the appearance of the choroid plexus. The primitive subarachnoid space appears earlier in the region ventral to the rhombencephalon than in the region posterior to the fourth ventricle. By stage 20, a primitive subarachnoid space almost completely surrounds the neural tube. A fairly-well developed primitive subarachnoid space was observed in the abnormal human embryo, in which the fourth ventricle was open to the amniotic cavity and the ventricular system was completely separated from the primitive subarachoid space. These findings imply that the extraventricular spread of fluid of choroid plexus origin is not an essential factors, and that probably it is not even an important factor, for the development of the subarachnoid space. The arachnoid villi dose not appear even at the end of the embryonal stage. Absorption of the cerebrospinal fluid in an embryo should be done by the way other than the arachnoid villi.
