Sperm mediated gene transfer

Pigs with expression of transgenes may be generated by sperm mediated gene transfer (SMGT).



The SMGT technique consists of the following steps (see schematic presentation here):


  • Collection of sperm cells from many different boars
  • Evaluation of sperm cell quality: motility, survival rate, morphology and ability to take up exogenous DNA
  • Preparation of transgene – linearized DNA is used for uptake in sperm cells
  • Removal of seminal fluid and mix with transgene – DNA uptake
  • Transfer of transgenic sperm cells to recipient sow by artificial insemination
  • Birth and molecular test of transgenic offspring
