AB  - Brain trauma leads to the induction of neural stem cell proliferation and the migration
of young neurons to injured areas. However, these neurons are insufficient to fully
restore neuronal function due to the limited potential of adult neurogenesis. This study
aimed to investigate the effect of hypoxia, a condition that underlines a wide spectrum
of brain pathologies, on pluripotency and the capacity of stem cells to differentiate
into neural progenitors. We analyzed the expression of SOX genes and microRNAs as
they control a variety of cellular processes during neuronal differentiation, including
cell proliferation and cell fate determination. In vitro neuronal differentiation of
human embryonal carcinoma cell line NT2/D1 and induced pluripotent stem cells
were used as a model system of adult neurogenesis. Cobalt chloride was used to
induce hypoxia.
The results of the analysis showed that, following hypoxia, the efficiency of neuronal
induction was significantly decreased, that coincident with decline in mRNA
expression levels of SOXB and SOXC genes. In contrast to that, the expression level of
miR-21 was significantly increased.
Our findings advance the study of SOX TFs, miR-21, and their possible interplay in
ischemia-related pathologies, establishing them as prospective biomarkers and
possible targets for future diagnostic and therapeutic approaches.

AB  - The in vitro generation of neural cells from human embryonic stem cells is a powerful tool to acquire better knowledge of the cellular and molecular events involved in early human neural and brain development under physiological and pathological conditions. Prenatal alcohol exposure can induce important anomalies in the developing brain, the embryogenesis being an important critical period for the craniofacial defects and mental disabilities associated with fetal alcohol syndrome. Here, we report the generation of neural progenitors (NPs) from human embryonic stem cells. Neuroepithelial progenitors display the morphological and functional characteristics of their embryonic counterparts and the proper timing of neurons and glia cells generation. Immunocytochemical and real time (RT)-polymerase chain reaction analyses reveal that cells appeared as clusters during neuroepithelial cell proliferation and that the genes associated with the neuroectodermal (Pax-6) and the endodermic (alpha-fetoprotein) lineages decreased in parallel to the upregulation of the genes of NPs (nestin and Tuj1), followed by their differentiation into neurons (MAP-2+, GABA+), oligodendrocytes [galactocerebroside (GalC+)], and astrocytes (GFAP+). We further demonstrate, for the first time, that human NPs express the endocannabinoid receptors (CB1 and CB2) and the enzymes involved in endocannabinoids synthesis (NAPE-PLD) and degradation (FAAH). Using this in vitro culture, we demonstrate that ethanol exposure impairs NPs survival, affects the differentiation of NPs into neurons and astrocytes, disrupts the actin cytoskeleton, and affects the expression of different genes associated with neural differentiation. The results provide new insights into the effects of ethanol on human embryogenesis and neuroprogenitors and offer an opportunity to delineate potential therapeutic strategies to restore early ethanol-induced brain damage.
