Micrographs of acute and chronic NGF exposed myoFB.

<p>Cells were exposed to different concentrations of NGF and stained with fluorescent DAPI or colorimetric TUNEL. (A-B) An increase of fluorescent cells showing nuclear condensation, picnotic nuclei and perimembrane vescicles is noticeable after acute and chronic NGF treatments. (C) TUNEL images from acute and chronic NGF exposed monolayers. (D) Histogram showing the % of TUNEL-positive NGF treated myoFB, over untreated ones (p<.05).
