The images obtained through the skull were very similar to those acquired by thinning or removing the skull. Immunohistochemistry evaluation revealed that the transplanted cells migrated towards the ischemic boundary zone and expressed the neuronal or astrocytic marker, supporting the findings on fluorescence optical images.

Therefore, it is critically important to develop an appropriate model of FCI in neonatal animals. We describe here a modified model of permanent FCI in rat pups at postnatal day-7 (P7). To produce permanent FCI, a suture embolus with different diameters (180–220 μm) was inserted into the left common carotid artery (CCA) of the pups with different weight (14–19 g). Then the suture embolus was advanced to the middle cerebral artery (MCA) to produce its occlusion. The success of vascular occlusion was evaluated by imaging the ischemic territory on serial brain sections with carbon black staining immediately after permanent FCI. The consistent cerebral infarction was confirmed by 2,3,5-triphenyltetrazolium chloride (TTC) staining 24 h after permanent FCI. Terminal deoxynucleotidyltransferase-mediated 2′-deoxyuridine 5′-triphospate-biotin nick end labeling (TUNEL) staining showed cell death with TUNEL labeling in the ischemic areas, which is one of the features of apoptosis.

Because direct physiological recording of postsynaptic currents are difficult to achieve, no information regarding the synaptic and dendritic events are available. This is due to the small size of the postsynaptic afferent nerve endings that do not allow a clear identification, and thus compromise direct electrophysiological recordings of the buttons. To study the physiology of afferent nerve endings, we have developed a two-photon imaging technique in cochlear and vestibular slice preparations from neonatal rats and turtles. This technique is based on a retrograde labeling of afferent nerve endings with high-affinity calcium-sensitive dyes. Dye filling was achieved by 6 h application of the dextran–amine conjugate of calcium green-1. Calcium changes were measured in afferent nerve endings in line scan and time lap mode. To address recording in a near-physiological situation, iontophoretic application of K+ was performed in the area of the stereocilia whereas glutamate was applied at the basal pole of sensory hair cells. Both types of application cause a reversible and sustained increase of Ca2+ in the button of afferent nerve fibers.

Much of the debate has centered on the identification of the dividing cells as neurons versus glia. Because neurogenesis has become a well-documented phenomenon, there is a need for reliable protocols to identify recently divided neurons in a wide range of situations. To facilitate the investigation of postnatal neurogenesis of magnocellular neurons in the pig hypothalamus, a sequential immunohistochemical staining technique was developed for use on serial sections of paraffin-embedded tissue. Proliferating neurons were labeled using mouse-derived monoclonal antibodies to detect proliferating cell nuclear antigen (PCNA) and vasopressin (VP). PCNA, a nuclear protein essential for cell division, identifies recently divided cells in the brains of healthy animals. VP is a unique functional marker for a mature neuron. The presence of a cell with VP positive cytoplasm and a PCNA positive nucleus demonstrates the presence of a VP-producing neuron that has recently divided. This protocol allowed us to safely and accurately label recently proliferated neurons in the mature pig hypothalamus and can be used on archived tissue. This data can be used for further morphometric analysis, as serial sectioning allows for three-dimensional reconstruction of hypothalamic nuclei.</div>","PeriodicalId":79477,"journal":{"name":"Brain research.
