Derivation of GS cells in a B6 background by PS48. (A) ECAR of GS cells cultured with GDNF and FGF2 for 3 d. n = 14 for control; n = 15 for FGF2 + GDNF. (B) ECAR of 7-d-old DBA or B6 germ cells cultured with GDNF and FGF2. n = 12 for DBA; n = 11 for B6. (C) Germ cell tumors found in recipient testis that underwent transplantation of testis cells overexpressing Myc or Mycn. (D) Appearance of DBA-GS and PS48-B6-GS cells. (E) ECAR of 7- to 8-d-old B6 germ cells cultured with GDNF, FGF2, and PS48. n = 14 for control; n = 13 for PS48. (F) Proliferation of B6-GS cells. Bars: C,D, 50 µm. The asterisk indicates a significant difference.
