Generally, target detection can be accomplished using chromogenic or fluorescent staining. Immunolabeling of cells (immunocytochemistry or ICC) or tissues ( immunohistochemistry or IHC) with antibodies to study neurons is a highly utilized application in Neuroscience mainly due to the availability of a wide range of markers and the relatively low cost for performing and imaging the immunolabeled material. Measurement of protein expression levelsÄownload our complimentary Neuronal Cell Markers Poster.Assessment of cellular or protein co-localization.Phenotypic and morphological analysis of neurons.microglia, astrocytes, and oligodendrocytes) Rather than undergoing cell death, some neurons can regrow axons and dendrites. If either type of process is removed, the cell cannot function. One example is the apical dendrite of the pyramidal neuron in the mammalian cortex, which is guided towards the pial surface by a gradient of attractive semaphorin 3A (Sema3A), a protein that repels axons. Neurons extend dendrites and axons to receive and send signals. Dendrites: are tree-like structures that extend away from the cell body to receive neurotransmitters from other neurons. Distinguishing neurons from other cell types in the nervous system (e.g. Similar to the axon, dendrite outgrowth and guidance are instructed by extrinsic signals.The use of antibodies for these markers in conjunction with microscopy serves as a powerful method for: ![]() ![]() These unique compartments are distinguishable using specific markers, and are generally classified into soma (cell body), axon, dendrite, and synapse. Dendrites receive and integrate signals from other neurons or from sensory stimuli, and conduct nerve impulses towards the axon or the cell body. Neurons have highly compartmentalized structures that allow their distinction from other cell types in the nervous system. An individual neuron can be viewed as a mosaic of structur- ally distinct cellular domains-cell body, dendrites, axon.
