BACKGROUND Because of their lipophilicity, persistent organic pollutants (POPs) cross the human placenta, possibly affecting central nervous system development. Most POPs are known aryl hydrocarbon receptor (AhR) ligands and activators of AhR signaling. Therefore, AhR activation has been suggested to cause developmental neurotoxicity (DNT). OBJECTIVE We studied the effects of AhR ligands on b...
NSCs are responsible for the generation of CNS cell types derived from the neural tube. Published data resulting from experiments studying the differentiation of NSCs in vitro or in vivo have confirmed their spontaneous tripotency, i.e. their ability to generate cells of the neuronal, astroglial and oligodendroglial lineages. The relationship between NSCs generated in vitro and ependymal cells ...
The identification of self-renewing and multipotent neural stem cells (NSCs) in the mammalian brain holds promise for the treatment of neurological diseases and has yielded new insight into brain cancer. However, the complete repertoire of signaling pathways that governs the proliferation and self-renewal of NSCs, which we refer to as the 'ground state', remains largely uncharacterized. Althoug...
There is a pressing need for patient-derived cell models of brain diseases that are relevant and robust enough to produce the large quantities of cells required for molecular and functional analyses. We describe here a new cell model based on patient-derived cells from the human olfactory mucosa, the organ of smell, which regenerates throughout life from neural stem cells. Olfactory mucosa biop...
Neural progenitor cells (NPCs) derived from human induced pluripotent stem cells (iPSCs) are traditionally maintained and proliferated utilizing two-dimensional (2D) adherent monolayer culture systems. However, NPCs cultured using this system hardly reflect the intrinsic spatial development of brain tissue. In this study, we determined that culturing iPSC-derived NPCs as three-dimensional (3D) ...
The characteristics of a material’s surface are extremely important when considering their interactions with biological species. Despite chemistry playing critical role in mediating the responses cells, there remains no single rule which dictates absolute performance; this is particularly challenging response differing cell types to range materials. Here, we highlight functional behavior neural...
Cancer stem cells or cancer initiating cells are believed to contribute to cancer recurrence after therapy. MicroRNAs (miRNAs) are short RNA molecules with fundamental roles in gene regulation. The role of miRNAs in cancer stem cells is only poorly understood. Here, we report miRNA expression profiles of glioblastoma stem cell-containing CD133(+) cell populations. We find that miR-9, miR-9(*) (...
