Mast cells in the chick embryo choroid plexuses.
Journal of Submicroscopic Cytology
|April 1, 1987
Summary
Mast cells were found in chick embryo choroid plexuses during later development. These cells may regulate choroid vessel permeability and fluid exchange between plasma and cerebrospinal fluid.
Area of Science:
- Developmental biology
- Immunology
- Neuroscience
Background:
- Mast cells are immune cells found in various tissues.
- Choroid plexuses produce cerebrospinal fluid (CSF) and form the blood-CSF barrier.
- The role of mast cells in embryonic choroid plexus development is not well understood.
Purpose of the Study:
- To investigate the presence and ultrastructure of mast cells in the developing chick embryo choroid plexus.
- To explore the potential function of these mast cells in regulating choroid plexus physiology.
Main Methods:
- Microscopical and ultrastructural analysis of chick embryo choroid plexuses.
- Observation from the 9th incubation day to hatching.
Main Results:
- Mast cells were identified within the perivascular connective tissue of the choroid plexuses.
- These cells exhibited morphological characteristics similar to mast cells in other embryonic organs.
- Their presence was noted in the later stages of embryonic development.
Conclusions:
- Mast cells exist in the developing chick embryo choroid plexus.
- These cells may play a role in regulating choroid vessel permeability.
- Mast cells could influence the exchange of substances between plasma and cerebrospinal fluid.
