METTL14 regulates chondrogenesis through the GDF5–RUNX–extracellular matrix gene axis during limb development [scRNA-seq]

Mettl14 forms a protein complex that induces m6A methylation on RNA but its roles in mouse limb development remains elusive. Here, the Mettl14 gene was knocked out in a limb bud-specific manner in Mettl14 flox/flox mice with the Prx1 promoter-driven cre. Dissociated cells from day 12.5 (E12.5) embryonic limb buds were applied to scRNA-seq to identify differentially expressed genes in a cell type-specific manner. Samples prepared from Per1cre;Mettl14 wild type/flox and Per1cre;Mettl14 flox/flox mice were labeled as cHet and cKO, respectively. Overall design: Single cells prepared from limb buds on E12.5 were applied to scRNA-seq.
