PURPOSE: Amyotrophic lateral sclerosis (ALS) or motor neuron disease is an adult-onset progressive neurodegenerative disorder. ALS-CSF has been shown to produce toxic effects on motor neuron cells like aberrant neurofilament phosphorylation and morphological alterations of nuclear and soma size. Our current study was designed to investigate the neuroprotective role of platelet derived growth factor (PDGF) in reverting the adverse effects produced by ALS-CSF.
METHODS: Our present study was carried out to determine the restorative potential of PDGF on the toxic effects of ALS-CSF on NSC motor neuron cells from patients. Therefore the cells were divided in to three groups: (a) normal control (NC) - the cells were not exposed to ALS-CSF; (b) ALS group - the cells were exposed to ALS-CSF; (c) NALS group - the cells were exposed to non ALS CSF. Further each of these groups was supplemented with PDGF.
RESULTS AND CONCLUSIONS: We observed that the mean area of nucleus and cell soma of the differentiated NSC motor neuron cells was significantly reduced in the cells exposed to ALS-CSF. We also observed that subsequent treatment with PDGF restored the soma area and nucleus of the ALS-CSF exposed cells significantly. Taken together, we show that supplementation with PDGF restores the morphological changes induced by ALS-CSF and PDGF may play a significant role in protecting motor neurons from apoptosis in ALS and thereby it promoting the cell survival.
