Me2SO perfusion time for whole-organ cryopreservation can be shortened: Results of micro-computed tomography monitoring during Me2SO perfusion of rat hearts.

Cryopreservation of whole organs and specific tissues is an important and continually expanding field of medicine. The protocols currently used for organ preservation do not ensure survivability and functionality; the protocols for ovarian tissue lead to acceptable outcomes, but these are still capable of further improvement. In general, cryopreservation protocols need to be optimized.

Chelidonium majus and its effects on uterine contractility in a perfusion model.

Objective: The herbal agent celandine is thought to have mainly spasmolytic effects, but in the uterus it is regarded as promoting contractions, which can offer promising and innovative options for optimizing artificial reproduction. The aim of the present study was to investigate the effect of celandine on the uterine muscle, using a perfusion model of swine uteri.

Study Design: Sixteen swine uteri were perfused with Krebs-Ringer solution.

Porcine uterus cryopreservation: an analysis of contractile function using different uterotonics.

Cryopreservation of whole organs has become increasingly successful in recent years, and establishing reliable methods for confirming the success of specific cryopreservation procedures has therefore become extremely important. On the assumption that methods such as histological evaluation do not provide definitive evidence of long-term cryopreservation and that clear signs of conserved function in an organ are good evidence of its viability, contractile function was analysed in porcine uteri (n=60), either after long-term (group A) or short-term (group B) cryopreservation and post-thaw treatment with three different uterotonics. A slow freezing protocol was used to preserve the organs.

Uterus cryopreservation in the sheep: one step closer to uterus transplantation.

Background: Uterus transplantation is the only way for women with no functional uterus to become pregnant. However, the technique is limited by the fact that an aggressive immunosuppression is necessary in order to avoid rejection of the graft. For better chances of finding a matching organ, which would minimize the immunosuppressive therapy, the establishment of cryobanks with a large number of uteri would be helpful.
