Adult neurogenesis has been the center of attention for decades. Neuroscientists hope to understand the mechanism underlying this phenomenon that might provide a unique perception of brain repair in future. Neurogenesis is referred to the process in which neuronal stem cells and progenitors generate new neurons in non-pathologic setting. Although there are some similarities between two neurogen...

Introduction: Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease. In the present study, we investigated the response of subventricular zone (SVZ) adult stem cells in the experimental autoimmune encephalomyelitis (EAE), an animal model of MS, and also the differentiation fate of these stem cells. Methods: Mice were immunized with MOG peptide emulsified in complete Freund'...

Intervertebral disc degeneration is a disease of the discs connecting adjoining vertebrae in which structural damage leads to loss of disc integrity. Degeneration of the disc can be a normal process of ageing, but can also be precipitated by other factors. Literature has made substantial progress in understanding the biological basis of intervertebral disc, which is reviewed here. Current medic...

The Asiatic hybrid lily, a bulbous ornamental plant, has a special position in the horticulture as cut flower. To overcome some problems in nutrition of bulb flowers, the use of hydroponic system and nutrient solution is important in the cultivation of these flowers. The Asiatic Hybrid Lilium bulbs “Tresor” cultivar, used for the current research were planted under 3 different calcium levels in...

Through adulthood, the rodent subventricular zone (SVZ) stem cell niche generates new olfactory bulb interneurons. We had previously reported that the number of new neurons produced in the SVZ declines through aging; however, age-related changes attributable specifically to the SVZ neural stem cell (NSC) population have not been fully characterized. Here, we conducted a spatiotemporal evaluatio...

Degenerative Disc Disease (DDD) is a prevalent musculoskeletal disorder associated with lower back pain that typically occurs age but can also be precipitated by other factors. At present, the available treatments such as physical therapy, analgesics, anti-inflammatory drugs, and surgical interventions are aimed at addressing symptoms of disease not degeneration process. Among various biologica...

New neurons are continuously added in specific regions of the adult mammalian central nervous system. These neurons are derived from multipotent stem cells whose identity has been enigmatic. In this work, we present evidence that ependymal cells are neural stem cells. Ependymal cells give rise to a rapidly proliferating cell type that generates neurons that migrate to the olfactory bulb. In res...

In the perinatal and adult forebrain, regionalized neural stem cells lining the ventricular walls produce different types of olfactory bulb interneurons. Although these postnatal stem cells are lineage related to their embryonic counterparts that produce, for example, cortical, septal, and striatal neurons, their output at the level of neuronal phenotype changes dramatically. Tiveron et al. inv...

Sensitive smell discrimination is based on structural plasticity of the olfactory bulb, which depends on migration and integration of newborn neurons from the subventricular zone. In this study, we examined the relationship between neural stem cell status in the subventricular zone and olfactory function in rats with diabetes mellitus. Streptozotocin was injected through the femoral vein to ind...
