Growth cones of cultured sympathetic neurons contain adrenergic vesicles
The growth cones of dissociated rat sympathetic neurons developing in culture were fixed with potassium permanganate to visualize vesicular stores of norepinephrine through the formation of granular precipitates. It was found that growth cones contain numerous small granular vesicles (SGV) 40-60 nm in diameter. The majority of the SGV was present in the varicosity of the growth cone but SGV als...
متن کاملExpression of CXCL10 in cultured cortical neurons.
Chemokines expressed in neurons are important mediators in neuron-neuron and neuron-glia signaling. One of these chemokines is CCL21 that activates microglia via the chemokine receptor CXCR3. As neurons also express CXCL10, a main ligand for CXCR3, we have thus investigated in detail the expression pattern of CXCL10 in neurons. We show that CXCL10 is constitutively expressed by neurons, is stor...
متن کاملDynamics of the endoplasmic reticulum and other membranous organelles in growth cones of cultured neurons.
The fluorescent lipophilic dye 3,3'-dihexyloxacarbocyanine iodide [DiOC6(3)] was used to examine the distribution of membrane-bound organelles in growth cones of cultured rat sympathetic neurons. Within chemically fixed growth cones, intense DiOC6(3) fluorescence was localized predominately to the base or central region of growth cones. However, in most growth cones several thin DiOC6(3)-fluore...
متن کاملGrowth cones are not required for initial establishment of polarity or differential axon branch growth in cultured hippocampal neurons.
Hippocampal neurons developing in culture exhibit two types of differential, seemingly competitive, process outgrowth in the absence of external cues. During the initial acquisition of polarity, one of several equivalent undifferentiated minor neurites preferentially grows to become the axon. Once the axon has formed, it typically branches, and the branches grow differentially rather than concu...
متن کاملInducing dendritic growth in cultured sympathetic neurons.
The shape of the dendritic arbor determines the total synaptic input a neuron can receive (1-3), and influences the types and distribution of these inputs (4-6). Altered patterns of dendritic growth and plasticity are associated with impaired neurobehavioral function in experimental models (7), and are thought to contribute to clinical symptoms observed in both neurodevelopmental disorders (8-1...
