Teratomas may arise from the aberrant migration of: (A) Epiblast, (B) Hypoblast, (C) Cytotrophoblast, (D) Syncy otrophoblast
Answer is A. Epiblast cells form the primordial germ cells, which migrate from the region of primitive streak to the region of future gonads to form the gametes like sperm & oocyte.Abnormal remnants of epiblast/primordial germ cells at the primitive streak or their aberrant migration lead to forma on of teratomas.
