Figure Lengend Snippet: Time‐dependent intracellular localization of Cy3‐labeled miRNA relative to the cell nucleus in L929 fibroblasts. Representative confocal microscopy images showing Cy3‐labeled miRNA (yellow) and DAPI‐stained nuclei (blue) in L929 fibroblasts treated with free miRNA (A), LNP‐miRNA (B), or LNP‐miRNA_dial (C) at the indicated time points (30 min, 1 h, 2 h, 4 h, and 24 h). Cy3‐miRNA signal is predominantly cytoplasmic and localized in the perinuclear region, with formulation‐dependent differences in the timing and intensity of intracellular miRNA appearance. Scale bar: 50 µm.
