Amyotrophic lateral sclerosis (ALS) is the most common adult onset motor neuron disease. The etiology and pathogenic mechanisms of the disease remain unknown, and there is no effective treatment. Here we show that intrathecal transplantation of human motor neurons derived from neural stem cells (NSCs) in spinal cord of the SOD1G93A mouse ALS model delayed disease onset and extended life span of...
In contrast to mammals, zebrafish regenerate spinal motor neurons. During regeneration, developmental signals are re-deployed. Here, we show that, during development, diffuse serotonin promotes spinal motor neuron generation from pMN progenitor cells, leaving interneuron numbers unchanged. Pharmacological manipulations and receptor knockdown indicate that serotonin acts at least in part via 5-H...
Purpose: The aim of this study was to evaluate the effect of NT-3 on the decrease of the differentiation time of bulge stem cells of rat hair follicle from neuron like cells.Materials and Methods: The bulge region of the rat whisker was isolated from and cultured in DMEM/F12 supplemented with epidermal growth factor (EGF) in 3 groups for 7, 8 and 9 days .Then 10 ng/ml NT-3 was added to each gro...
Human embryonic stem (ES) cells are undifferentiated pluripotent cells derived from the inner cell mass of blastocyst stage embryos. These unique cell lines have the potential to form virtually any cell type in the body and can be propagated in vitro indefinitely in an undifferentiated state. These cells are capable of forming embryoid bodies (EB) that contain cells from all three embryonic lin...
objective(s): nowadays much effort is being invested in order to diagnose the mechanisms involved in neural differentiation. by clarifying this, making desired neural cells in vitro and applying them into diverse neurological disorders suffered from neural cell malfunctions could be a feasible choice. thus, the present study assessed the capability of fetal brain extract (fbe) to induce rat bon...
Motor neuron and musculoskeletal diseases are the most frequently inherited muscular disorders. Motor neuron diseases are mostly found among people within 35-70 years of age, which selectively affect the motor neurons. Amyotrophic lateral sclerosis (ALS) is the most common variant of motor neuron diseases that progressively degenerates the motor cells in the brain and spinal cord, so that the m...
While microRNAs have emerged as an important component of gene regulatory networks, it remains unclear how microRNAs collaborate with transcription factors in the gene networks that determines neuronal cell fate. Here we show that in the developing spinal cord, the expression of miR-218 is directly upregulated by the Isl1-Lhx3 complex, which drives motor neuron fate. Inhibition of miR-218 suppr...
Background: Spinal muscular atrophy (SMA) is a genetic motor neuron disease caused by mutations in the SMN1 (Survival Motor Neuron) gene, which leads to hypotonia, muscle weakness and respiratory involvement. Its most severe form, SMA type 1, starts before 6 months of life has high mortality due ventilatory failure. Nusinersen, first approved treatment for SMA, an antisense oligonucleotide intr...
