We recognized small groups with features of cap cells or TF cells (selective expression of Lmx1a (LIM homeobox transcription factor 1a), engrailed (en), decapentaplegic (dpp), and wingless (wg); 43 cells) [33–36], stalk cells and their precursors (selective expression of Lamin C (LamC; also expressed in TF and cap cells) and single-minded (sim); 23 cells) [32], and germline cells (selective expression of zero population growth (zpg), chinmo (chronologically inappropriate morphogenesis), ovo, ovarian tumor (otu) and vasa; 34 cells) (Additional file 1: Fig. S1) [32]. Here, LMNA is linked to ovarian neoplasm.
