The presence and localization of synapsin I were investigated in the cat vestibular epithelium, using a rabbit anti-synapsin I antibody. The staining was performed by immunofluorescence or by a peroxidase-anti-peroxidase technique. A strong immunoreactivity was observed with both methods. It appeared as spherical patches distributed in the lower part of the(More)
Early afferent innervation and differentiation of sensory vestibular cells were studied in mouse embryos from gestation day (GD) 13 to 16. Afferent neurites were found as early as GD 13 in the epithelium when there were no clearly differentiated sensory cells. By GD 14 the earliest sensory cells which exhibited short hair bundles at their luminal pole were(More)
The effect of transecting the vestibular nerve on the vestibular sensory epithelium was studied in adult guinea-pigs. When denervation was complete, after fifteen days, the vestibular hair cells began to show morphological features of immaturity. After two months, the majority of hair cells showed a supporting cell phenotype. By four months, both hair cells(More)
The intracellular space between sensory hair cells and nerve endings and between supporting cells of the vestibular epithelia in the cat contains a fine network of microstructures arranged obliquely between the cell membranes of adjacent cells. In situ immersion-perfusion fixation, electron microscopy complemented by lanthanum negative-contrast and(More)
The maturing process of afferent innervation of the vestibular sensory cells in the cat was studied during both the fetal and postnatal stages. Although the type II cells from the 36th day of gestation already have an innervation similar to that found in the adult, it is not the same for the type I receptor cells. Only 75% have a complete innervation from(More)
In the course of postnatal development in the cat, there is a decrease of about 93% in the total number of synaptic bodies (synaptic balls and synaptic bars) in type I hair cells. In type II hair cells, there is no change in the number of synaptic balls. Simultaneously, the length of specialized neuroepithelial contact increases by approximately 300% during(More)
The maturation of the innervation of the sensory hair cells of the cristae ampullares was studied in the newborn cat. The essential characteristics of the adult are already present in the type II cells at this age. The type I cells on the contrary reveal different degrees of maturation. It was observed that in the immature stages the efferent endings which(More)
Rotation-mediated aggregate cultures of foetal rat liver cells were prepared and grown in a chemically defined medium. Their capacity for cellular organisation and maturation was studied over a culture period of 3 wk by using both morphologic and biochemical criteria. It was found that within each aggregate, distinct liver cell types were present and(More)
To assess the association between growth indicators of Serbian children aged <5 years of Roma and non-Roma populations and social determinants of health. This study used a cross-sectional secondary data analysis design to measure national and Roma population samples from the MICS 4 (UNICEF) performed in 2010 in Serbia. A total of 4,978 questionnaires were(More)
