This article discusses the discovery of the first known menstruating rodent, the spiny mouse, and proposes that a significant increase in progesterone during the luteal phase is a unique feature of menstruating species, but reports no new experimental results.

This review discusses using human follicular fluid in metabolomic analysis as a diagnostic tool and predictor of success in assisted reproductive technology for PCOS patients, reporting no new results.

This collection of reviews, edited by Ken Lukowiak and Janis Weeks, explores diverse sensory systems across species, including olfaction, echolocation, magnetoreception, and visual adaptations, without presenting new experimental results.

This study reported that Pantaneiro sheep from the Pantanal region of Brazil exhibit greater genetic variability and adaptability compared to the commercial Texel breed, highlighting their potential for further research and importance in Brazilian sheep farming.

This study investigated the genetic basis of coat color variation in cattle using skin transcriptome and whole-genome analyses, identifying the ASIP gene as a significant determinant that is differentially expressed and under strong positive selection in black and brown cattle breeds.

In this study, researchers found that the absence of P-selectin delays inflammatory cell recruitment and reepithelialization in fetal wounds, although scar formation still occurs in later gestation wounds.

In this study, Akt2 and the oncogenic protein Tcl1 were found to be essential for early blastomere proliferation and embryo development in preimplantation mouse embryos.

This study reports that Wise is expressed in specific patterns during the morphogenesis of chick embryos, particularly in regions associated with known signaling molecules like Wnt, Bmp, and Shh.

This study suggests that an in ovo injection of CHIR-99021 promoted feather growth and follicle development in goose embryos by activating the Wnt signaling pathway.

This study found that the PP2A-B55α regulatory subunit is crucial for ectodermal development in mice, with knockout embryos displaying severe neural and epidermal defects and failing to survive to birth.

This study identified several candidate genes related to wool production traits and adaptation to hot, arid environments in Iranian sheep, highlighting potential targets for future inbreeding programs.

This article discusses the potential benefits of platelet-rich plasma injections in ovarian tissue to improve reproductive outcomes in IVF for older individuals and proposes a mechanism to enhance embryo ploidy rescue, but reports no new clinical results.

This review discusses factors affecting fertility in both men and women with congenital adrenal hyperplasia and emphasizes individualized preconception management but reports no new clinical results.

In this study on tolerant rats, maternal and developmental toxicity from levo-alpha-acetyhnethadol hydrochloride were observed at all doses, without specific fetal toxicity or teratogenic effects.

This review highlights similarities in the development of thymus and skin epidermis, reporting no new results; the authors emphasize shared molecular mechanisms despite different embryonic origins.

This study found that intrauterine PRP infusion is a safe and effective treatment for patients with refractory thin endometrium and implantation failures, with the improvement primarily driven by the angiogenic cytokines in PRP.

Mouse Scube3 affects teeth, tongue, vibrissae, and eye development, but not facial structure or limb growth.

This study used whole-genome resequencing to analyze genetic diversity and selection in 17 rabbit breeds, identifying genes linked to traits like coat color and body size, which could inform breeding and conservation efforts.

This study suggests that mouse lineage specification during pre-implantation development involves distinct timing and mechanisms for trophectoderm and inner cell mass differentiation, challenging existing models.

This study found that both natural and environmental selection have significantly influenced the goat genome, revealing genetic loci tied to adaptation, fitness, and productive traits, more so than artificial selection, across various goat populations.

This study reports that the autotaxin–LPA–LPA3 signaling pathway at the embryo-epithelial boundary plays a critical role in decidualization by up-regulating HB-EGF and COX-2 in the uterine epithelium.

This study observed that high concentrations of rosemary and thyme extract caused thymic tissue damage, decreased IgM and IgG levels, and fluctuated IL-10 levels in chick embryos, with inflammation signs present despite potential benefits.

In this study, transiently activating the sonic hedgehog signaling pathway in chickens transformed reticulate scales on the feet into feathers comparable to body feathers, without ongoing treatment, suggesting this pathway affects the diversity of bird skin appendages.

The researchers reported that scaffoldin, a protein identified in chicken embryos, likely plays a role in forming periderm granules and contributes to the soft cornification of embryonic epidermis.

This commentary discusses the feasibility and challenges of uterine transplantation for transgender women, emphasizing anatomical, hormonal, and ethical considerations without reporting new clinical results.

This review summarizes how single-cell omics technologies have advanced understanding of cellular regulatory programs in sheep and goats, but highlights limitations in genomic annotation and integration with population genetics for molecular breeding.

This study suggests that mNotch expression plays a significant role in hair follicle differentiation and cell fate selection within the follicle during development.

This review discusses the effects and selection criteria of different progestogens in various treatments but reports no direct clinical comparisons of their metabolic effects.

This review discusses the role of LPA(3) in embryo implantation and its genetic connection with prostaglandin signaling, but reports no new clinical results.

This study found that back skin mesenchyme from mouse embryos can induce hair follicle formation even before dermal condensate formation, but R-spondin-1 alone or with a Bmp receptor inhibitor was not sufficient for hair follicle induction.
