Uterus transplantation

G Testa, E C Koon, L Johannesson
The uterus is the most recent addition to the list of organs that can be successfully transplanted in humans. This paper analyzes living donor uterus transplantation according to the ethical principle of equipoise. A comparison is made between living donor uterus transplantation and gestational surrogate motherhood. Both are solutions to absolute uterine infertility that allow the transfer of genetic material from intended parents to a child. The analysis concludes that living donor uterus transplantation does not violate the ethical principle of equipoise and should be considered an ethically acceptable solution to absolute uterine infertility...

The uterine transplant is an innovative surgical procedure whereby a healthy uterus is transplanted into a woman with uterine factor infertility (UFI) for the purpose of procreation. Twelve uterine transplants have been attempted in the world in the last two decades, and five have led to viable births. While uterine transplantation is still in its experimental stages, it remains unclear whether Canadian centres plan to attempt the procedure in the near future. Herein, I raise several observations that are specific to the Canadian setting and apply the Montreal Criteria for the Ethical Feasibility of Uterine Transplantation to determine whether there is fertile ground for a uterine transplantation program to be adopted in Canada...

INTRODUCTION: We present a case report of ectopic pregnancy (EP) after simultaneous pancreas-kidney transplantation (SKPTx). PRESENTATION OF CASE: A 33-year-old female status post SKPTx suddenly got abdominal pain in the lower level. She had high human chorionic Gonadotropin test. Ultrasonography revealed that there was no fetus in the uterus but a dilated right fallopian tube, which strongly suggested ectopic pregnancy. An emergency operation was performed and a dilated right side uterine tube was found with adhesions to her transplant...

AIM: To describe class I and II human leucocyte antigen (HLA) expression using different uterine tissues in the perspective of uterus transplantation. METHODS: Human uterine tissues were obtained from 12 women who had undergone hysterectomy for the treatment of benign disease. HLA class I and HLA-antigen D related (DR) expression were assessed via immunochemistry. HLA class I expression in the uterus was compared with expression in other organs and tissues, including kidney and myocardium samples...

Absolute uterine factor infertility affects 3-5% of the general population, and unfortunately this condition is untreatable. There are some available options, including surrogacy or adoption, but neither of these suits each and every woman who desires to have her own genetic child. With recent advances in surgery and transplant immunology, uterus transplantation may be a source of hope for these women with uterine infertility. In the last decade, a number of animal species including rats, mice, rabbits, pigs, sheep, and primates have been used as experimental models, and pregnancies were achieved in some of these...

AIMS: To investigate the therapeutic effects of bone marrow-derived mesenchymal stem cells (BMSCs) transplantation on intrauterine adhesions (IUA). METHODS: BMSCs were isolated and labeled by green fluorescence protein. IUA model was established by mechanical injury. 48 rats were randomly divided into control, IUA model, BMSCs vein injection and BMSCs intrauterine injection groups (n=12 in each group). The third generation of BMSCs was injected through tail vein or intrauterine...

BACKGROUND: The aim of this systematic review was to evaluate and compare the pros and cons of using living donors or brain-dead donors in uterus transplantation programs, 2 years after the first worldwide live birth after uterus transplantation. METHODS: The Medline database and the Central Cochrane Library were used to locate uterine transplantation studies carried out in human or non-human primates. All types of articles (case reports, original studies, meta-analyses, reviews) in English or French were considered for inclusion...

It has been reported that patients receiving renal replacement therapy (RRT), including dialysis and kidney transplantation, tend to have an increased risk of cancer; however, studies on the degree of this risk have remained inconclusive. The present meta-analysis was therefore performed to quantify the cancer risk in patients with RRT. Cohort studies assessing overall cancer risk in RRT patients published before May 29, 2015 were included following systematic searches with of PubMed, EMBASE and the reference lists of the studies retrieved...

OBJECTIVE: Uterine infertility (UI), which can be caused by a variety of congenital or acquired factors, affects several thousand women in Europe. Uterus transplantation (UTx), at the current stage of research, offers hope for these women to be both the biological mother and the carrier of their child. However, the indications of UTx still need to be defined. The main aim of the study was to describe the different etiologies of UI and other data as marital and parental status from women requesting UTx who contacted us in the framework of a UTx clinical trial...

Endometriosis is an estrogen-dependent, progesterone-resistant disorder largely derived from retrograde transplantation of menstrual tissue/cells into the pelvis, eliciting an inflammatory response, pelvic pain and infertility. Eutopic endometrium (within the uterus), giving rise to pelvic disease, displays cycle-dependent transcriptomic, proteomic, and signaling abnormalities, and while its DNA methylation profiles dynamically change across the cycle in healthy women, studies in endometriosis are limited. Herein, we investigated the DNA methylome and associated gene expression in three phases of the cycle in eutopic endometrium of women with severe endometriosis versus controls, matched for ethnicity, medications, smoking, and no recent contraceptive steroid use...

Endometriosis is a painful condition characterized by growth of endometrial cysts outside the uterus. Here, we tested the hypothesis that peripheral innervation and prostaglandin levels contribute to endometriosis-associated pain. Female Sprague-Dawley rats (n = 16) were surgically instrumented by transplanting uterine tissue onto mesenteric arteries within the peritoneal cavity to create a model of endometriosis which forms extra-uterine endometrial cysts and vaginal hyperalgesia. Our results describe a significant positive correlation between endometriosis-induced vaginal hyperalgesia and cyst innervation density (sensory, r = 0...

PURPOSE OF REVIEW: Vascularized composite allotransplantation (VCA) encompasses hand, face, uterus, penile and lower extremity transplantation. Psychosocial factors are recognized as important, but no standard approach to the evaluation, selection or posttransplant care has been described and thus, the development of a standardized approach is needed. RECENT FINDINGS: Various psychosocial assessment tools have been reported. Body image and the functional impact of hand versus face transplantation are notable issues...

BACKGROUND: As a definition, Endometriosis is a commonly encountered gynecological disease; as endometrial glandular and stromal cells existing in the outside of the uterus. In spite of several studies on endometriosis, its molecular mechanism and pathogenesis nevertheless have been not completely illuminated. Role of ELAM-1 gene in mediating the adhesion of tumor cells to endothelial cells by binding to ELAM-1 ligands expressed by eosinophils, neutrophils, monocytes, natural killer cell effectors T-lymphocyte cell, and cancer (progenitor/stem) cells is well studied...

Bone marrow (BM)-derived cells (BMDCs) contribute to endometrial regeneration. Our objective was to develop a non-gonadotoxic mouse bone marrow transplant (BMT) model using 5-fluorouracil (5-FU) for investigating BMDCs trafficking in reproduction. Female C57BL/6J mice received either single (CTX-1) or paired (CTX-2) 5-FU (150mg/Kg) dose, or single (CTX-1+SCF) or paired-dose (CTX-2+SCF) 5-FU with stem cell factor (SCF). Control mice received BMT only or saline. BM cells (20×10(6)) from transgenic green-fluorescent protein (GFP) mice were injected intravenously...

Endometriosis is observed in ∼10% of reproductive age women. Ovarian endometriosis not only causes dysmenorrhea but also infertility and a high risk of adenocarcinoma. Due to its scattered nature, complete surgical resection is difficult. Endometriosis consists of glandular and stromal cells. Previously, we showed that endometrial stromal cells (ESCs) play a role in the protection against pathologic events caused by monthly repeated hemorrhage. Here, we undertook a preclinical study of non-thermal plasma (NTP) as a surgical treatment of endometriosis...
