Soluble factors increase the numbers of Hes3+ cells in the adult rat hippocampus.(a) Treatment with the soluble factors induced a powerful increase in the number of Sox2+ cells in the hilus [Quantifications are from images taken from the tip of the hilus to approximately 1,300 micrometers towards the CA3 region – representative images are shown. Staining for the young neuron marker doublecortin (DCX) helps to visualize the subgranular zone]. (b) The same treatment also induced an increase in the numbers of Hes3+ cells in the hilus. (c) Sox2+ cells inside the hilus co-expressed Hes3; in contrast, Sox2+ cells in the subgranular zone did not co-express Hes3. (d,e) Quantification graphs of the increases in Sox2+ and Hes3+ cell numbers in the hilus (p<0.05). For the graph, the number of cells in the sham operated control animals was set to 100%.

Fluoxetine inhibits the differentiation of hypothalamic neuroprogenitor cells.Hypothalamic neuroprogenitor cells were differentiated for 18 days, in the presence or absence of fluoxetine (1 µM). Representative confocal photomicrographs for mature neurons marker Neu-N (green) (A). Fluoxetine decreases the percentage of Neu-N positive cells and the incubation with Trk receptors inhibitor K252a (24 h) partially reverses this effect (B). Representative confocal photomicrographs for the progenitor cells marker SOX-2 (green) (C). Fluoxetine increases the percentage of SOX-2 positive cells and the incubation with K252a (24 h) does not change this effect (D). Fluoxetine does not up regulate the levels of neurotrophic factor BDNF but incubation with K252a (24 h) results in a compensatory increase of BDNF mRNA levels (E). DAPI (blue), nuclear staining.

Neural induction of hPSCs. (a) Both hPSC culture and neural differentiation were performed on LN521 substrate. Cortical neurons were induced with dual SMAD inhibition, expanded in the presence of FGF2, and matured with support by a selection of neurotrophic factors. Neural progenitor cells (NPCs) could be cryopreserved at day 21 and plated at day 32 for final experiments, including microelectrode array (MEA) measurements. (b) Three different hPSC lines (one hESC line, 08/023 and two hiPSC lines, 10212.EURCCs and IMR90-4) were characterized for their efficiency in producing neuroectodermal cells in response to 12-day neural induction by dual SMAD inhibition. Cells were stained for pluripotency marker Oct4 at the pluripotent stage and after 12 days of neural induction. The presence of early neuroectodermal markers was evaluated with Sox2, FoxG1 and Pax6 staining. (c) After 21 days of differentiation, the culture contained vimentin- and Pax6-positive NPCs that could be cryopreserved. Additionally, the first Tbr2- and MAP2-positive neurons were detected at this time point. (d) The percentages of Pax6-positive cells were quantified at four time points of differentiation (mean ± s.e.m., n = 5–14, data derived from 1–3 independent differentiations). Statistical analysis was performed with the Mann-Whitney U test to compare differences between day 12 and day 46 within each hPSC line, and significant p-values are presented in the image. The scale bar is 50 µm in all images. Image collected and cropped by CiteAb from the following publication (https://pubmed.ncbi.nlm.nih.gov/31748598), licensed under a CC-BY license.
