Abstract

To determine whether adult human dorsal root ganglion neurons can be isolated and maintained in long-term tissue culture, where they would extend processes. Dorsal root ganglia were removed from adult human organ donors within 2 hours of clamping the aorta. They were then treated with enzymes for one hour, triturated to dissociate the neurons and their satellite cells, and the individual neurons were then plated in tissue culture dishes in medium containing serum. Isolated adult human dorsal root ganglion neurons survive in vitro for more than 2 1/2 months, in the absence of exogenously supplied neurotrophins. where they remain electrically excitable and extend processes, Isolated adult human dorsal root ganglion neurons survive in culture for more than 2 1/2 months, extend processes, and remain electrically excitable, without exogenous neurotrophins. These results suggest that, adult human sensory neurons do not require exogenous neurotrophins for survival and process outgrowth, or that sufficient factors were provided by the small number of satellite cells in the cultures. In addition, the neurons survive well in spite of an initial period of up to 14 hours of hypoxia, between the time the aorta was clamped and when the plate...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function.
