Organotypic spinal cord culture in serum-free fibrin gel: a new approach to study three-dimensional neurite outgrowth and of neurotoxicity testing: Effects of modulating the actin and tubulin dynamics and protein kinase activities.
    Journal of neuroscience methods, 1997, Dec-30, Volume: 78, Issue:1-2

    Spinal cord explants from embryonic day seven (E7) chicken embryos were cultured without serum and in the presence of aprotinine, in a three-dimensional fibrin matrix. These conditions promote a robust, radial, unfasciculated outgrowth of neurites that are tipped by elaborate growth cones. Routinely after 5 days, the neurite outgrowth intensity (NOI) was determined by measuring the optical density of the immunostained neurites (image analysis program OPTIMAS version 5.2) within defined areas, extending radially for up to 3 mm from the explant border. A dose-dependent inhibition of NOI was determined for the cytoskeleton-affecting drugs nocodazole (half maximal inhibition ([I50]), 0.02 microM), taxol ([I50], 0.016 microM), cytochalasin D ([I50], 0.006 microM), and tetramethyl lead ([I50], 0.05 microM). Likewise, NOI was decreased in a dose-dependent fashion by ML-9 and RO-31-8220, inhibitors of myosin-light chain kinase and protein kinase C (PKC), respectively. The addition of 1,2-dioctanoyl-s,n-glycerol, a potent activator of PKC, led, at 5 microM, to an increase and at 30 and 60 microM to a decrease in NOI. The described system provides a rapid, reproducible, and quantitative assay for the effects of exogenous factors on the mode and intensity of neurite outgrowth.
