Figure Lengend Snippet: Confocal immunofluorescence images of S2-013 and HPNE cells that took up SNORA22 siRNA conjugated with FA-Dab8α and FA-Dab8γ. A S2-013 cells were incubated with Alexa Fluor 647-labeled chemically modified SNORA22 siRNA-FA-Dab8α and SNORA22 siRNA-FA-Dab8γ (green). Blue, DAPI staining. Scale bars, 10 µm. B Quantification of Alexa Fluor 647-labeled chemically modified SNORA22 siRNA-positive cells in A. Data represent the number of cells positive for the siRNA, scored across five fields per group and derived from two independent experiments. Columns , mean; bars , SD. * p <0.05 significantly different from SNORA22 siRNA-FA-Dab8γ (the Student’s t -test). C S2-013, S2-CP8, and HPNE cells were incubated with Alexa Fluor 647-labeled chemically modified SNORA22 siRNA-FA-Dab8α (green). Cells were stained with an anti-FOLR1 antibody (red). Blue, DAPI staining. Scale bars, 10 µm. D Quantification of Alexa Fluor 647-labeled chemically modified SNORA22 siRNA-positive cells in C. Data represent the number of cells positive for the siRNA, scored across five fields per group and derived from two independent experiments. Columns , mean; bars , SD. * p <0.05 significantly different from HPNE cells (the Student’s t -test)

Article Snippet: This solution was added to each well, followed by a 48-h incubation with the addition of 1 mL of fresh DMEM at 24 h. Cells were then fixed with 4% paraformaldehyde, followed by immunostaining using an anti-folate receptor 1 (FOLR1) antibody (MAB5646, R&D Systems, Minneapolis, MN, USA) and DAPI staining (HardSet Mounting Medium with DAPI, Vector Laboratories, Burlingame, CA, USA).

Figure Lengend Snippet: Localization of SNORA22 siRNA-FA-Dab8α and SNORA22 siRNA-FA-Dab8γ within lysosomes of S2-013 cells. Confocal immunofluorescence images show S2-013 cells incubated with Alexa Fluor 647-labeled chemically modified SNORA22 siRNA-FA-Dab8α and SNORA22 siRNA-FA-Dab8γ (green) and stained for lysosomes (LysoTracker, red) and nuclei (DAPI, blue). Cells enclosed in white boxes are shown at higher magnification below each panel to clearly demonstrate the specific colocalization of the nucleic acid compounds within the lysosomal compartments. Scale bars, 10 µm

Article Title: The influence of simulated microgravity on MG-63 osteoblast-like cells cultured on polymeric scaffold

doi: 10.1016/j.bbiosy.2026.100137

Figure Lengend Snippet: Live/dead staining results in Experiment 1 (A, C, E, G) and Experiment 2 (B, D, F, H) of MG-63 cells cultured on (A, B) Glass, (C, D) Sc _plate, (E, F) Sc _v_static, (G, H) Sc _v_RPM. Living cells stained green by calcein-AM, dead cells stained red by propidium iodide. Phalloidin/DAPI staining results in Experiment 2: (B2) Glass, (D2) Sc _plate, (F2) Sc _v_static, (H2) Sc _v_RPM. Actin filaments stained green by phalloidin, cell nuclei stained blue by DAPI. Glass – cells seeded on glass coverslips and cultured in standard conditions (37 °C, 5 % CO 2 ), Sc _plate – cells seeded on scaffolds in the well plates and cultured in standard conditions (37 °C, 5 % CO 2 ), Sc _v_static – cells seeded on scaffolds, enclosed in the vials (37 °C), Sc _v_RPM – cells seeded on scaffolds, enclosed in the vials (37 °C), and subjected to the 60 rpm (Experiment 1) and 10 rpm (Experiment 2) settings on the RPM. Scale bar =100 µm.
