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 study found that conditioned medium from human placental cells or tissue promoted angiogenesis in HUVECs in vitro, with early-pregnancy placental cells and whole placental tissue showing more significant effects.

This review examines rodent models to explore how maternal conditions like undernutrition, obesity, hypoxia, and androgen exposure affect fetal programming and metabolic outcomes in offspring, but presents no new clinical findings.

This study concluded that placental mesenchymal stem cells from aborted fetal tissue may serve as an in vitro model for studying spontaneous abortion mechanisms and potential regenerative therapies due to their abnormal gene expression and differentiation capabilities.

This study found that the subtilisin protease Sub3 from Microsporum canis is essential for adherence to the feline epidermis but is not necessary for invading epidermal structures.

This study found that human placenta extract may be a promising pulp-capping material, causing less intense chronic inflammation and thicker dentine bridge formation compared to mineral trioxide aggregate in dogs' teeth.

This article reviews human placenta hydrolysates and their complex molecular mechanisms in treating various conditions but does not present new clinical findings.

The study found that conditioned medium from placental cells and sub-cultured placental tissue promoted angiogenesis in HUVECs, with early pregnancy cells showing more significant effects than those from full-term pregnancy.

This study suggests that maternal hyperandrogenism and insulin resistance may induce ferroptosis in the gravid uterus and placenta in rats, but through distinct molecular mechanisms.

This study found that ΔNp63α directly regulates VDR expression, which in turn may reduce invasiveness in an epidermoid cancer cell line.

In this study, researchers developed a 3D-printed vascular model to analyze how different shear stresses influence cell behavior and promote cellular organization around neovessels, offering insights into tissue engineering for wound reconstruction.

This report describes a 33-year-old woman who developed alopecia neoplastica due to gastric adenocarcinoma, highlighting the role of tumor invasion in hair follicle atrophy.

This study found that bioactive extracts from goat placenta, particularly when delivered via dissolving microneedles, enhanced fibroblast proliferation and skin regeneration without being toxic to skin cells, suggesting a promising dermal application for improving skin health.

This study found that NKB placental mRNA expression was higher in women with PCOS, particularly in pregnancies with female offspring, suggesting its involvement in PCOS-related placental dysfunction.

This study suggests that hair follicles may be the primary target in the onset of various skin diseases, potentially spreading to affect the surrounding epidermis.

This review discusses the potential of human placental extract (HPE) in cartilage regenerative medicine for osteoarthritis, noting its significant anti-inflammatory and regenerative properties observed in vitro and in vivo studies, but reports no new clinical results.

This review discusses peptide "biogenic stimulants" from human placenta extracts, highlighting their potential wide-ranging clinical applications across multiple diseases, and reports no new clinical results.

This study found that conditioned medium from placental cells and sub-cultured placental tissue promoted angiogenesis in human umbilical vein endothelial cells in vitro, with early pregnancy cells having a more significant effect.

This study found that local injections of fetal tissue mesenchymal stromal cells in mice significantly improved healing and hair follicle density after high-dose radiation-induced skin damage.

This study identifies SOX9 as a critical downstream effector of ERG in TMPRSS2:ERG fusion-positive prostate cancer, indicating its role in tumor invasion and growth.

In this study, mice lacking podoplanin in epidermal keratinocytes showed reduced tumor cell invasion and peritumoral lymphangiogenesis, suggesting that keratinocyte-expressed podoplanin contributes to advanced stages of skin tumor progression.

Wnt/β-catenin signaling is crucial for cell fusion in placental development.

This study found that keratins 5, 7, 8, and 19 are expressed in human trophoblast cells while vimentin is solely expressed in stromal-mesenchymal cells, aiding in placental cell type identification.

This paper explores the complex immune processes and cellular diversity that enable the skin to heal and resist invasion, and highlights its potential as a model for studying regeneration.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study investigated transcription factors in human trophectoderm cells during development, finding that GATA2 and GATA3 are essential for transforming stem cells into induced trophoblast stem cells, which display characteristics similar to placental progenitor cells, offering new methods for modeling placental-associated diseases.

This review discusses biological sex differences in COVID-19 outcomes and reports no new clinical results; it identifies a need for studies to clarify how sex influences disease progression.

This review examines the potential of K18 as a diagnostic and prognostic marker in epithelial-derived tumors, highlighting its specific expression in tumor tissues and interaction with proteins involved in tumor progression, without reporting new clinical findings.

This study found that Epstein pearls and Mongolian spots are the most common skin lesions in newborns in India, influenced by interracial, environmental, and hormonal factors.

This study found that nearly half of the tinea capitis patients at a Surabaya hospital had cat contact, with the most common symptoms being crust and hair loss.
