Figure Lengend Snippet: USP18 deficiency inhibits the growth of ccRCC organoids (A and B) Bright-field (A, scale bars, 500 μm) and H&E (B, scale bars, 100 μm) images showing the morphology and structure of ccRCC organoids from three patient samples. (C and D) IF data show the expression of CK7 (C) and Vimentin (D) in ccRCC organoids (scale bars, 100 μm). (E) Bright-field images showing the morphology of control and USP18-deficient ccRCC organoids. “Before” indicates the bright-field image of the organoids after transfection with shNC/shUSP18 at 72 h, and “after” indicates the bright-field image of the organoids after transfection with shNC/shUSP18 at 96 h. The images taken before and after are of the same organoids at different time points in the same field of view. (F) Change in diameter (%) of control and USP18-deficient ccRCC organoids. (G) ATP assay indicating the viability of control and USP18-deficient ccRCC organoids. (H and I) Western blot data indicate the expression of USP18, YBX3, P-AKT, and P-PI3K in control and USP18-deficient ccRCC organoids. Unpaired two-tailed Student’s t test was employed for p -value calculation. Data are represented as mean ± SD.

Article Title: Droplet Microfluidics‐Assisted Fabrication of Magnetite Nanoparticle Hybrid Microgels for Facile Protein Immobilization

doi: 10.1002/cbic.202500958

Figure Lengend Snippet: Fabrication and stability of biotin‐functionalized hybrid microgels loaded with MNPs. (A) Scheme illustrating droplet microfluidics‐assisted fabrication of biotin‐functionalized, poly(acrylamide)‐based hybrid microgels with MNPs. HµGel‐XB denotes biotinylated microgel, where X indicates biotin‐PEG‐acrylamide concentration in the precursor solution in % ( w/w ). Following ultrasonic treatment, the precursor solution is injected into microfluidic channels with flow‐focusing design (as shown in the AutoCAD design). Crosslinking of water‐in‐oil (W/O) emulsion droplets occurs via UV irradiation within the outflow tubing. (B) MNP stability in the precursor solution over time demonstrated by bright‐field microscopy images of purified microgels containing 1% ( w/w ) MNP and 2.5% biotin (HµGel‐2.5B) after 1.5 and 3.5 h of experimentation, respectively. Insets show uniform distribution of MNPs within the microgels and reveal consistent MNP loading during microfluidic processing over time. All scale bars denote 150 μm.
