Until now, many researchers have been trying to find new medical plants and their components, which can promote neurogenesis in the neurogenic regions, as a potential therapeutic agent of neurodegenerative diseases and many studies have demonstrated that some plant extracts and their components have the capacity to promote neurogenesis.[26],[27] Although some researchers recently showed that extracts of plants in the family Umbelliferae including Oenanthe javanica and Angelica sinensis improved cell proliferation and
neuroblast differentiation in the SGZ of the hippocampal DG,[28],[29] neurogenic effects of GLein the brainhave not yet been investigated.
At D3, there were no significant differences in
neuroblast density between PB-MNC+, PB-MNC, and PBS groups (52,262 [+ or -] 14,825 [micro][m.sup.2]; 47,579 [+ or -] 14,099 [micro][m.sup.2]; and 57,225 [+ or -] 21,634 [micro][m.sup.2], resp.) or in the migration distance of DCX+ cells toward the ischemic area (825.6 [+ or -] 177.4 [micro]m; 618.8 [+ or -] 184.5 [micro]m; and 765 [+ or -] 135.5 [micro]m, resp.) (N = 4 - 5) (Figure 7).
In addition, a significant decrease in the number of
neuroblasts (DCX-positive immature neurons) in the YAC128 hippocampal DG was observed at 6 months of age.
A single tumor may contain a wide range of cellular phenotypes characteristic of this transient embryonic structure, in particular
neuroblasts, melanocytes, and nonneuronal cells such as Schwann, perineurial, or satellite cells.
Neuroblasts were positive for vimentin and S100 (Figure 1E), specifically in the nucleus and cell membrane, and exhibited discrete positive staining for NSE in the cytoplasm (Figure 1D).
There are no
neuroblasts seen in the current specimen, which was submitted entirely (Figure 5).
Type A cells are proliferating
neuroblasts that form chains to migrate, while type B cells are similar to astrocytes morphologically [9].
The migration of
neuroblasts that will form the myenteric plexus begins in small intestines at I.U.
Stress by noise produces differential effects on the proliferation rate of radial astrocytes and survival of
neuroblasts in the adult subgranular zone.
Ibuprophen attenuates the inflammatory response and allows formation of migratory
neuroblasts from grafted stem cells after traumatic brain injuries.
Neuroblastoma is an embryonic malignancy arising from the
neuroblasts which show tremendous clinical heterogeneity.
PHOX2B was positive in
neuroblasts and ganglion cells and showed reactivity in 75% of undifferentiated NBs, 100% of poorly differentiated NBs, and 96% of differentiating NB/ganglioneuroblastomas.
