Transplantation of ovarian tissue is a valuable method to rescue mouse strains with fertility problems and to revitalize archived strains.The purpose of this study was to investigate the effect of (i) different sizes of transplanted ovary pieces on reproductive outcome, (ii) use of immunodeficient recipients to overcome the limitation of histocompatibility, and (iii) to compare different protocols for cryopreservation of ovarian tissue.Halves, quarters, and eights of mouse ovaries were transplanted.

All four cryopreservation protocols used were able to preserve functionality of the ovarian tissue.Transplantation of ovarian tissue smaller than halves resulted in reduced litter sizes.The distribution of ovarian tissue of one donor female to 4 or 8 recipients will therefore yield in a higher total number of offspring in a certain time period.The use of immunodeficient recipients is an option for non-histocompatible donors.

Moreover, the breeding of genetically modified lines with serious welfare problems can be refined by transplantation of their ovaries into healthy wildtype recipients.For successful reconstitution of recipient fertility, ovaries have to be either freshly transferred or archived within 2 h without cooling  or within 4 h stored at 4 °C  after death of the donor and transferred after thawing.Mostly whole ovaries are transferred [1, 2, 6,7,8, 11,12,13], but in some studies, half ovaries are used [3,4,5, 8, 9] and sometimes even quarter pieces [9, 14].
To split the ovaries into smaller pieces simplified the transfer procedure compared with the transfer of whole ovaries.Additionally, in cryopreservation studies, the permeation of tissue with cryoprotectants was improved by reduction of the tissue size.However, published results between different studies are not comparable because of the use of different parameters like donor age (from day 16 of pregnancy  via 10–16 days [6, 7, 13] up to 12 weeks ), mouse strains (BALB/c [2, 7], FVB , C57BL/6 , C3H , ICR , or DBA ), recipient age (4 weeks [9, 13] up to 12 weeks , penetrating cryoprotective agent (DMSO [2,3,4, 6,7,8, 11, 12, 14], ethylene glycol , DMSO ethylene glycol , DMSO acetamide propylene glycol , DMSO acetamide propylene glycol polyethylene glycol ), or the cryopreservation method (vitrification [9, 13, 14] or slow freezing [2,3,4,5,6,7,8,9, 11, 12, 14]). Forex broker mac platform. [[To our knowledge, there is no systematic comparison of the transfer of different sized ovary pieces in mice.A prerequisite for engraftment of transplanted tissue is the histocompatibility between donor and recipient determined by the genes of the major histocompatibility complex (MHC).Without histocompatibility, the transplant will be rejected.

Therefore, donors of outbred strains with undefined mixed genetic background are not suitable because of the absence of appropriate histocompatible recipients.In the International Mouse Strain Resource (IMSR), more than 286,000 strains are listed but only 883 are indicated as inbred or major histocompatible (A possible strategy to overcome this incompatibility problem is to use very young recipients without a fully developed immune system . But this approach induces technical problems due to the small size of the very young recipients.Alternatively, adult immunodeficient mouse mutants could serve as universal recipients but are still rarely used for the transplantation of mouse ovaries [12, 14].In contrast, immunodeficient mice have frequently been used for xenotransplantation as recipients for ovary pieces from the rat , human [16,17,18,19,20,21], sheep [22, 23], cat [24, 25], cattle [26, 27], wombat , elephant , dog [30, 31], and lion .
Cryopreservation of ovarian tissue offers a valuable additional resource to the routinely used gametes and embryos for archiving and fertility recovery.In reproductive medicine, freezing of ovaries with subsequent thawing and surgical engraftment can restore fertility in young women undergoing cancer treatment with chemo- and/or radiotherapy [33,34,35,36].Moreover, ovarian tissue can be a valuable tool to preserve important lines or strains of laboratory, domestic, and wild animals. Sanitärhandel erlangen. Frozen ovaries may offer a valuable addition to the current cryopreservation approaches with embryos and gametes.Although different protocols for the cryopreservation of mouse ovaries were published, a direct comparison of fertility parameters after transplantation of thawed ovarian tissue is still missing [2,3,4,5,6,7, 11, 12, 37,38,39].We have selected four very different protocols from the literature with regards to the physical process (vitrification, slow freezing), containment (straw, cryo tube), and cryoprotective agent (dimethyl sulfoxide (DMSO), acetamide, ethylene glycol).
Here, we address different aspects of transplantation and cryopreservation of ovarian tissue of mice in order to maximize the benefit of the procedures for practical application.All animals were housed in Macrolon® cages, lined with bedding (Lignocel®, heat treated, Rettenmaier Austria Gmbh & Co.KG, Vienna, Austria), and enriched with nesting material (Pur-Zellin 4 × 5 cm; Paul Hartmann Gesmb H, Wiener Neudorf, Austria), in a rodent facility (room temperature 21 ± 1 °C [mean ± SEM]; relative humidity 40–55%; photoperiod 12L:12D).

Food (V1126, Ssniff Spezialdiaeten Gmb H, Soest, Germany) and tap water were available ad libitum.The specific pathogen-free status was confirmed quarterly according to FELASA (Federation for Laboratory Animal Science Associations) recommendations .Experimental procedures were discussed and approved by the institutional ethics committee and granted by the national authority under license numbers BMWF-68.205/0258-II/3b/2011, BMWF-68.205/0023-II/3b/2014 and BMBWF-68.205/0062-V/3b/2018.
Ovary donors were sacrificed by cervical dislocation immediately before transplantation and dissected ovaries were stored in M2 medium (M7167-100 ml, Sigma-Aldrich Handels Gmb H, Vienna, Austria) at 37 °C for at most 60 min.Recipients were anesthetized by intraperitoneal (i.p.) injection of Ketamine/Xylazine (100 mg/kg BW Ketamine (Ketasol), 4 mg/kg BW Xylazine (Rompun), Graeub Veterinary Products, Bern, Switzerland) and eyes were covered with eye ointment (Oleovit, Fresenius Kabi, Graz, Austria) during surgery.After disinfection with 70% ethanol, an incision of the skin and the peritoneum was made lateral close to the ovary for gentle extraction of the ipsilateral reproductive tract.

To unwrap the ovary, the ovarian bursa, a transparent tissue membrane that covers the ovary, was opened with fine iris scissors for a distance of a few millimeters directly along the ovarian fat pad.For ovariectomy, the ovarian ligament which held the ovary in place was cut with fine scissors.After stopping bleeding from the cut vessels, a new piece of ovarian tissue (according to the experimental protocol: experiment 1, 2, or 3) was orthotopically grafted without fixation and wrapped with the bursa.
