Figure Lengend Snippet: Human Neural Progenitor Cells (NPCs) display increased neurite outgrowth when cultured with exosomes and CM from MCF-7 Snail cells compared to MCF-7 Neo. MCF-7 Neo or MCF-7 Snail was cultured in exosome-depleted medium (Exo-D medium) for 3 days, and conditioned medium (CM) was collected, or exosomes were isolated from the CM. These were subsequently cultured with NPCs for 2 days. (A) Images of NPC after incubation in NPC regular medium, Exo-D medium, exosomes or CM with or without Talin1 inhibitor mH4 were captured with a Nikon Eclipse TE2000-S Inverted Fluorescence Microscope. (B) The percentage of NPCs with neurite outgrowth and average neuron length was measured utilizing Image J Fiji Just software in NPCs cultured with NPC medium, Exo-D medium, and Exo-D medium plus NGF-beta as a positive control. The percentage of NPCs with neurite outgrowth and average neuron length of NPCs cultured with (C) exosomes isolated from MCF7-Neo and MCF7-Snail CM or (D) CM from MCF7-Neo and MCF7-Snail was analyzed using ImageJ Fiji Just software. Statistical analyses were done using GraphPad Prism software (one-way ANOVA, Šídák's multiple comparisons test, ****p< 0.0001, ***p< 0.001, **p < 0.01, *p < 0.05). Bars represent the SD of the mean. Results are representative of 3 experiments performed independently.

Article Snippet: Neural Progenitor Cells (ACS-5004), NPC Growth Medium (ATCC ACS-3003), DMEM: F12 (ATCC 30-2006) and Cell Basement Membrane (ACS-3035) were purchased from American Tissue Cell Culture (ATCC), Manassas, VA. Talin1 inhibitor, mH4 and F3 protease inhibitor control, was obtained from Dr. Kensei Tsuzaka, Kaytee Bio, Co. & Ltd., Chiba, Japan. mH4 was dissolved in DMSO to a stock solution of 14 mg/ml.

Figure Lengend Snippet: Human neural progenitor cells (NPCs) display reduced neurite outgrowth with exosomes and CM from C4-2 Snail knockdown (C4-2 E8) cells compared to C4-2 Non-silencing (NS) cells. C4-2 NS or C4-2 E8 was cultured in exosome-depleted medium (Exo-D medium) for 3 days, and conditioned medium (CM) was collected, or exosomes were isolated from the CM. These were subsequently cultured with NPCs for 2 days. (A) Images of NPC after incubation in NPC regular medium, Exo-D medium, exosomes, or CM with or without Talin1 inhibitor mH4 were captured with a Nikon Eclipse TE2000-S Inverted Fluorescence Microscope. The percentage of NPCs with neurite outgrowth and average neuron length of NPCs cultured with (B) exosomes isolated from MCF7-Neo and MCF7-Snail CM or (C) CM from MCF7-Neo and MCF7-Snail was analyzed using ImageJ Fiji Just software.

Figure Lengend Snippet: Establishment of the GSC–neuron coculture. ( a ) Neuron differentiation: iPSC-derived NPCs were induced to differentiate into neurons for three weeks and were characterized for the neuronal markers Tuj1 (green) and NeuN (red). Cell nuclei were stained with DAPI (blue). ( b ) Establishment of the GSC–neuron coculture: NeuN + neurons were used for the cocultures. GFP + GSCs (NSC11 and NSC20) were added directly to the neurons in the GSC media for 48 h to establish the coculture. The figure shows representative images of the GSCs (GFP: green)–neurons (NeuN: red) in the direct coculture. The images were captured with a confocal microscope using a 40× lens, and images of the neurons are presented as orthogonal projections.

Figure Lengend Snippet: UV (254 nm) vs. laser (808 nm) cytotoxicity assay in human neural progenitor cells (hNPCs). ( a ) hNPCs were grown in culture for 3 days prior to UV or laser treatment, and viability assays were performed 24 h after. Immunofluorescence images show the expression of NPC markers SOX1 and Nestin. ( b ) UV irradiation at energy densities 30, 60, & 90 J/cm 2 significantly decreased the viability of hNPCs after 24 h in a culture determined via CCK-8 assay. ( c ) Laser irradiation at energy densities 30, 60, & 90 J/cm 2 did not affect hNPCs viability. The statistical significance of the data was analyzed using one-way ANOVA with Tukey’s multiple comparisons test for each group (**** P < 0.0001)

Figure Lengend Snippet: Photocleavable nanoparticle (PCN) cytotoxicity assay in human neural progenitor cells (hNPCs). ( a ) hNPCs were grown in culture for 3 days prior to PCN or laser treatment, and viability assays were performed after 24 h. ( b ) Concentrations of PCN up to 900 µg/mL exhibited no cytotoxic effect on hNPCs. ( c ) Laser irradiation in combination with PCNs at energy densities of 30, 60, and 90 J/cm 2 , did not affect hNPC viability after 24 h in culture, as determined by the CCK-8 assay. ( d ) Immunofluorescence images show the presence of PCNs in hNPCs, confirming that hNPCs remained viable after treatment and laser irradiation. Groups were compared using one-way ANOVA with Tukey’s multiple comparisons test
