The tissue of the central nervous system is made up of two classes of cells that may be broadly categorized as neurons and glia. Neurons are anatomic, functional, and trophic units of the brain. Despite great variability in size and shape, all neurons share common morphologic features, which are those of the key elements of a highly complex communication network. The neurons are the dynamically polarized cells that serve as the major signaling unit of the nervous system. The human brain is known to contain about 1 x 10^11 neurons, each being able to contact at least 10,000 other neurons.HN from AcceGen Research Laboratories are isolated from the human brain. HN are cryopreserved at primary cultures and delivered frozen. Each vial contains ＆gt;1 x 10^6 cells in 1 ml volume. HN are characterized by immunofluorescent method with antibodies to neurafilament, MAP2, and beta-tubulin III. HN are negative for HIV-1, HBV, HCV, mycoplasma, bacteria, yeast and fungi. HN are guaranteed to further culture in the conditions provided by AcceGen Research Laboratories.
