Immunofluorescent Light Micrograph of astrocytes with other neuroglial precursor cells cultured in the laboratory These cells constitute the non conducting special connectivetissue in the brain This tissue is known as neuroglia nerve glue Starshaped astrocytes light green perform a function of supplying nerve cells with nutrients and may store nerve information Other cells here are busy forming into different types of neuroglia nervesupport tissue Cell nuclei stain blue Immunofluorescence is a staining technique which uses antibodies to attach fluorescent dyes to specific tissues and to molecules within the cell Magnification x at mm x at xcm
