MP Term : abnormal stellate reticulum morphology [MP:0030522] Mammalian Phenotype

Namespace  MPheno.ontology Obsolete  false
description  any structural anomaly of the network of star-shaped cells found in the core of the dental (enamel) organ between the stratum intermedium and outer enamel epithelium which secrete hydrophilic glycosaminoglycans into the extracellular compartment; the stellate reticulum is most fully developed at the bell stage when intercellular spaces become fluid-filled, presumably related to osmotic effects arising from the high concentration of glycosaminoglycans; the main function of the stellate reticulum is mechanical, protecting the underlying dental tissues against physical disturbance and maintaining tooth shape
