While lineage segregation becomes morphologically apparent at the 16-cell stage, increasing evidence suggests that molecular asymmetries emerge much earlier. Here, we systematically profile the transcriptome of whole embryo and individual blastomere of mouse embryos at 2-cell and 4-cell stage using SMART-Seq2.2026/06/01GSE300864GSM9069836GSM9069858GSM9069859GSM9069837GSM9069838GSM9069839GSM9069861GSM9069840GSM9069841GSM9069842GSM9069843GSM9069844GSM9069845GSM9069823GSM9069846GSM9069824GSM9069860GSM9069825GSM9069847GSM9069848GSM9069826GSM9069849GSM9069827GSM9069828GSM9069829GSM9069850GSM9069851GSM9069852GSM9069830GSM9069853GSM9069831GSM9069854GSM9069832GSM9069833GSM9069855GSM9069856GSM9069834GSM9069857GSM906983524247300864Mus musculus
