Description

Intracellular dye injections of protoplasmic astrocytes from the CA1 region of hippocampus of a 4 week old rat reveals highly ramified spongiform processes. Astrocytes were filled with Lucifer Yellow. Optical sections were generated with a single photon confocal microscope, and compiled here as a single maximum projection image. This image has been downsampled from the raw data image which can be accessed using the link provided to the Cell Centered Database.

Technical Details

Male Sprague Dawley rats, 4 weeks of age, were anesthetized and perfused transcardially with with Ringer’s solution (37°C), followed by 4% paraformaldehyde (PFA) in PBS (37°C, pH 7.4). Tissue was sectioned (100 µm thick) using a vibratome, and injected with a BX50WI microscope (Olympus, Melville, NY) and, using infrared differential interference contrast videomicroscopy, cells with a small diameter soma (approx. 7–11µm) in the stratum radiatum of CA1 were located and impaled with glass micropipettes filled with 5% aq. Lucifer Yellow. The astrocytes were filled using 0.5 Hz pulses of current until all of the processes were brightly fluorescent. After several astrocytes were filled, a slice was placed in the 4% PFA overnight at 4°C. Slices were then imaged after coverslipping in Gelvatol. Confocal images were acquired with a BioRad Radiance2000 (Hercules, CA) attached to a Nikon E600FN (Kanagawa, Japan) microscope equipped with a Nikon (Tokyo, Japan) 60x oil objective (NA 1.4).
