update publication information. We collected 3 replicates of whole stomach organs at 15 time points that covered embryonic days (E12.5, E13.5, E14.5, E15.5, E16.5, E17.5, E18.5), postnatal days (D1, D3, D5), and postnatal weeks (W1, W2, W3, W6, W8). The sampling time window covered from the earliest day that stomach sampling is anatomically feasible to the latest weeks when stomachs are close to mature. We applied a fast-seq proteomics workflow, a label-free quantitative proteomics approach in combination with small scale reverse phase pre-fractionation strategy.
