Abstract
Here, we present a protocol for localized gene knockdown in embryonic mouse hindlimb explants using direct small interfering RNA (siRNA) injection, combined with a semi-quantitative morphology scoring system to assess developmental outcomes. We describe steps for mating of samples, preparing hindlimb explants for culture and siRNA-Lipofectamine complex, and direct injection of the siRNA-Lipofectamine complex. We then detail procedures for explant culture and maintenance, data analysis, tissue fixation, and cryoprotection. This protocol approach enables spatially precise modulation of gene expression during limb and joint development.
