Pituicytes are glial cells of the posterior pituitary that store and release hormones. They are similar to astrocytes and may form rare tumors called pituicytomas.
Pituicytes are specialized astroglia cells in the neurohypophysis that regulate the secretion of oxytocin and vasopressin. Learn about their morphology, distribution, function and relation to pituitary tumors.
The meaning of PITUICYTE is one of the pigmented more or less fusiform cells of the stalk and posterior lobe of the pituitary gland that are derived from glial cells.
Pituicyte-enriched factors provide a local microenvironment that instructs a permeable neurovascular conduit. Thus, genetic and pharmacological perturbations of Vegfa and Tgfβ3 affected HNS vascular morphogenesis and permeability and impaired the expression of the fenestral marker plvap.
Pituicytes are elongated, uni- or bipolar cells with a fibrillary, piloid cytoplasm (Fig. 1). Similar to glial cells of other areas of the central nervous system, pituicytes expand processes to adjacent neuronal axon or to a blood vessel wall. At ultrastructural level, pituicytes appear to exist in five principal forms: (1) Major (or normal or light): the common type and reminiscent of ...
Pituicyte is a type of cell in the posterior lobe of the pituitary gland, related to neuroglia. Learn more about its function, structure and synonyms from different medical sources.
Pituicytes are neuroglial cells in the posterior pituitary gland that support the nerve terminals and capillaries. Learn about their structure, function, and related topics from various books and articles published by Taylor & Francis.
Pituicytomas originate from pituicytes, modified glial cells derived from ependymal lineage that are found in the stalk and posterior lobe of pituitary gland. The clinical presentation is similar to other pituitary tumors and imaging exams may ...
Why some blood vessels become permeable while majority of brain vessels form a blood-brain barrier remains unclear. Anbalagan et al. show that pituicytes, resident astroglial cells of the neurohypophysis, provide a local microenvironment that regulates the decision of endothelial cells to adopt a permeable endothelial fate instead of forming a BBB.
The hypothalamo-hypophyseal system is supplied with two types of specialized glial cells that interact in neuroendocrine functional dynamics: the tanycytes and the pituicytes. Tanycytes are the dominating glial cells within the median eminence. Similar to radial glia, they extend from the floor of t …
