<prompt> Teratomas may arise from the aberrant migration ofEpiblastHypoblastCytotrophoblastSyncy otrophoblast  <response>: 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 epiblastprimordial germ cells at the primitive streak or their aberrant migration lead to forma on of teratomas.
