Fluorescence micrographs demonstrating robust survival of adult human DRG neurons with elaborate axonal networks that could be maintained in culture for at least 3 months. The human DRG neurons were identified by immunoreactivity to antibodies specific for DRG neurons: A, CGRP or neurofilament proteins; B, RMO-254; C, SMI-31; and D, neurofilament-200. Each neuron cell body is ~ 50 μm in diameter.
