Mouse Assisted Reproductive Technology (MART)

The Mouse Assisted Reproductive Technology (MART) Core staff are experienced in collecting mouse sperm, harvesting unfertilized eggs, conducting in-vitro fertilization and embryo transplantation. In addition, to eliminate common mouse pathogens in the offspring born to mice of uncertain health status (example, mice coming from other facilities and countries), we perform cesarean section, embryo transfer, and in-vitro fertilization.

Mouse Strain Rederivation

  • Import Rederivation: Live Strain Rederivation using caesarean section and cross-fostering
  • Embryo Transfer (ET ): fresh embryos
  • Embryo Transfer (ET ): frozen embryos
  • In Vitro Fertilization (IVF): fresh sperm
  • In Vitro Fertilization (IVF): frozen sperm
Sperm Cryopreservation

  • Sperm Recovery and Cryopreservation

Cryobank Repository Service

All of the above procedures are conducted in our ABSL-2 laboratories to preserve the specific pathogen-free health status of our mouse colonies and breeding program.

Disclaimer:  Overall performance using the above reproductive technologies tends to be a function of genetic strain viability.
