ABSTRACT
Objective:
The present study aims to evaluate the viability of adult human neural cells in culture obtained from traumatized brain tissues collected in emergency surgery procedures.Methods:
Exploratory, descriptive, quantitative and cross-sectional study evaluating samples obtained from patients who underwent traumatic brain injury with extrusion of brain tissue submitted to cell culture in a standardized medium, being preserved during 168h. After observation under phase contrast microscopy and immunohistochemical processing for neuronal (MAP-2) and glial (GFAP) markers, morphometric parameters of neural cells (cell body area, dendritic field length and fractal dimension) were evaluated using ImageJ software, with data obtained after 24, 72 and 168h being compared using non-parametric Kruskal Wallis test, followed by Dunn's post hoc test.Results:
The explant of the nervous tissue revealed a consolidated pattern of cell migration into the culture medium. Cell proliferation, upon reaching confluence, presented an aspect of cellular distribution juxtaposed along the culture medium at all time points analyzed. Both neurons and glial cells remained viable after 168h in culture, with their morphologies not varying significantly throughout the time points evaluated. Immunohistochemistry for MAP-2 showed a relatively well-preserved cytoskeletal organization. GFAP immunoreactivity revealed activated astrocytes especially at the later time point.Conclusions:
Our results point out the viability of cell culture from traumatized human nervous tissue, opening up perspectives for the use of substances of natural origin that may contribute neuroprotectively to neuronal maintenance in culture, allowing future translational approach.Assuntos
