Figure Lengend Snippet: bPGCLC induction. (A) Scheme for the direct induction of bPGCLCs from bES cells. (B) PGCLC induction with a WNT agonist plus WNT antagonist. Shown are bright-field (BF), fluorescence images and FACS analysis of D4 aggregates of bES cells. BT, BLIMP1-tdTomato. TN, TFAP2C-mNeonGreen. Scale bar: 200 µm. (C) Scheme for the induction of bPGCLCs under the culture conditions indicated. (D) bES cells after 24 h of incubation under the conditions indicated. (E) PGCLC induction with BMP4 and a WNT antagonist. Shown are bright-field (BF) and fluorescence images and FACS patterns of D4 aggregates of bES cells after 24 h of pre-incubation. BT, BLIMP1-tdTomato. TN, TFAP2C-mNeonGreen. Scale bar: 200 µm. (F) PGCLC induction from various cell lines. C1-144 yielded the most BTTN-positive cells when the BMP4 concentration was 200 ng/ml, while C11-928 and N5-319 were best when the BMP4 concentration was 50 ng/ml. The concentration of CHIR was 6 µM in the all experiments. FACS analyses were done on day 4 of PGCLC induction. BT, BLIMP1-tdTomato. TN, TFAP2C-mNeonGreen. Scale bar: 200 µm.
Article Snippet: Existing targeting vectors were treated with restriction enzymes, and mNeonGreen sequences were amplified by PCR from LifeAct-mNeonGreen (98877; Addgene) and cloned using an in-fusion HD cloning kit (TaKaRa Bio, Shiga, Japan).
