Objective: Embryo-derived PreImplantation Factor (PIF) is essential for pregnancy immune modulation and synthetic PIF (sPIF), reverses neuroinflammation, and prevents diabetes mellitus through its immune modulatory properties. Herein, we explore sPIF's systemic effects on peripheral blood mononuclear cells (PBMCs).
Study Design: sPIF's effects on PBMCs and subset populations from nonpregnant patients (n = 7) and male patients were evaluated by the assessment of binding characteristics, mixed lymphocyte reaction, proliferation, cytokine secretion, and associated gene expression. Data analysis was by analysis of variance (P < .05).
Results: Fluorescein isothiocyanate-sPIF bound all myelomonocytic cells; binding was 30-fold up-regulated in mitogen-activated T and B cells (P < .05). sPIF decreased mixed lymphocyte reaction by 70% and blocked anti-CD3 antibody stimulated-PBMC proliferation by approximately 80% (P < .05). In naïve PBMCs, sPIF reduced interleukin (IL)-10 and -2; in activated PBMCs, sPIF increased IL-4, -5, -10, and -2, tumor necrosis factor-α, interferon-γ, and granulocyte-macrophage colony-stimulating factor (P < .05).
Conclusion: Physiologic concentrations of PIF exert potent systemic antiinflammatory effects on nonpregnant activated immune cells.

The trophectoderm (TE) is the first tissue to differentiate during the preimplantation development of the mammalian embryo. It forms the outer layer of the blastocyst and is responsible for generating the blastocoel, a fluid-filled cavity whose expansion is essential for successful hatching and implantation. Here, we investigated the role of the small GTPase RHOA in the morphogenesis of the TE, particularly its relationship with HIPPO signaling, using mouse embryos as a model.

Optimal embryonic development depends upon cell-signaling molecules released by the maternal reproductive tract called embryokines. Identity of specific embryokines that enhance competence of the embryo for sustained survival is largely lacking. The current objective was to evaluate effects of three putative embryokines in cattle on embryonic development to the blastocyst stage.

Objective: To compare the cost-effectiveness of a gestational carrier to a uterine transplantation in the treatment of absolute uterine-factor infertility.
Design: We performed a cost-effectiveness analysis using a decision-tree mathematical model comparing a gestational carrier to a uterine transplantation.
Subjects: Published literature was used to derive costs for solid organ transplant, immunosuppression, gestational carrier obtainment, in vitro fertilization, preimplantation genetic testing, and frozen embryo transfer.

Background/aims: Preimplantation genetic diagnosis (PGD) with human leukocyte antigen (HLA) typing represents a significant advancement in treating inherited hematological disorders, particularly thalassemia major. This technology enables the birth of healthy children who can serve as compatible stem cell donors for their affected siblings. Turkey is a world leader in both PGD+HLA typing technology and hematopoietic stem cell transplantation from savior siblings born through PGD+HLA typing.
