We previously reported that the construction project near the MCN-III vivarium caused high rates of pregnancy loss and pup mortality, which impaired our ability to operate efficiently. We are now pleased to report that our pregnancy loss and pup mortality rates have returned to their historical baselines, as shown below.

Due to the nature of our work, during most of the recent COVID-19 shutdown, we were permitted to continue pushing projects forward until May, when we took a short pause. We have now resumed performing all microinjection and cryopreservation services and are accepting new projects. Despite these challenges, we produced twenty-seven new mouse models for sixteen VU/VUMC investigators between January 2019 and May 2020.

Pregnancy loss and pup mortality rates increased during construction period. Pre-construction = 2/1/2018 to 3/11/2019. n = 365 implementations (I), n = 1102 pups born (PB). Construction 3/18/2019 to 11/19/2019. n = 221 l, n = 366 PB. Post-construction = 11/26/2019 to 3/31/2020. n = 143 l, n = 350 PB. Statistical data comparison to Pre-construction. ***, P<0.0002. n.s., not significant. 2 x 2 contingency table, Fisher's exact test, 2 tailed.
