The video illustrates an immunofluorescence staining method used to examine neurogenesis in the adult hippocampus. Initially, a mouse brain section undergoes treatment with primary antibodies directed at marker proteins associated with neurogenesis in neuronal progenitor cells. Next, it is labeled with secondary antibodies tagged with fluorophores. The brain section is then observed under a confocal microscope to distinguish various subtypes of progenitor cells, based on the expression patterns of distinct combinations of marker proteins.
Protocol
All procedures involving animal models have been reviewed by the local institutional animal care committee and the JoVE veterinary review board. 1. Tissue Preparation Prepare 4% formaldehyde in 0.1 M phosphate buffer pH 7.4 on the day before perfusion. Store at 4 °C. Transcardially perfuse the deeply anesthetized mice (3.5% isoflurane) via the left ventricle with 10 ml ice-cold phosphate-buffered saline (PBS), then with 40 ml ice-cold formaldehyde (f…
Representative Results
Figure 1. Schematic illustration of transferring microtome slices into a 24-well plate. Start at A1 and place subsequent slices into row A; after A6, go to the next row B, and so forth. When reaching D6, go back to A1 and continue. This arrangement of slices allows for quantification of every nth section of an entire brain. For quantification of newborn cells, take every 6th…
