In this study, loss of epidermal Par3 in mice disrupted the skin barrier and affected cell differentiation and stem cell maintenance, highlighting its role in epidermal homeostasis.

This review outlines the processes and potential of stem cells in regenerating skin, hair, and other tissues but presents no new experimental findings.

Stem cells compete for space using cell adhesion, and mutations can affect their competitive success, with implications for tissue health and disease.

This study found that Bacillus/Trapa japonica fruit ferment filtrate extracts enhanced human hair follicle dermal papilla cell proliferation through the Akt/ERK/GSK-3β signaling pathway, suggesting potential benefits for alopecia treatment.

In a study using a mouse model, HF-MSCs were reported to enhance ovarian function in cyclophosphamide-induced premature ovarian failure more effectively than HU-MSCs, potentially by preventing ferroptosis in granulosa cells via the KEAP1/NRF2/HO-1 pathway.

This study found that γδ T cells play a role in regulating stromal behavior, influencing the composition and vascularity of fibrotic tissues during the foreign body response.

This study used a 3D live imaging system to map cell dynamics in human hair follicles, revealing patterns of cell movement and division that help explain hair fiber extrusion during hair growth.

This study reviews the potential of stem cell-based therapies, including transplants and exosome treatments, to reactivate hair follicle stem cells and promote hair growth in individuals experiencing pattern hair loss.

This study established the R-7 dermal papilla cell line, which retained essential characteristics of primary cells without undergoing malignant transformation, suggesting its potential for future hair research.

This study found that external light can rapidly activate hair follicle stem cells in animals via a retinal light-sensing pathway linked to the central and autonomic nervous systems.

This review discusses the use of Dermal Papilla cells as in vitro models for studying hair growth modulators, emphasizing their role in aiding the development of new hair treatments, but reports no new clinical results.

The study suggests that a 3D culture system using the RAD16-I peptide scaffold can help restore the original phenotype of hair follicle dermal papilla cells and support their osteogenic and adipogenic differentiation.

This study identified three main ethical concerns regarding stem cell use from an Islamic perspective in Malaysia, focusing on embryonic stem cells, aesthetic applications, and therapeutic medicine.

This study observed that stem cells from the hair follicle dermis share similarities with bone marrow-derived mesenchymal stem cells and have potential to form neural-like cells under specific conditions.

This study demonstrates that transfected epidermal stem cells using a novel 3D transfection system significantly enhanced wound healing and may serve as an effective therapeutic agent and gene delivery method for wound treatment.

This review discusses the evolution of lineage-tracing strategies over the past century, emphasizing their role in identifying progenitor cells and resolving debates about cellular origins, with no new results reported.

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.

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

This study found that individualized homeopathic medicine can significantly improve outcomes in patients with alopecia areata, including complete hair regrowth and reduced SALT scores within 5 to 12 months, without relapse, and shows promise for alopecia universalis through targeted miasmatic and constitutional remedies.

This study found that Cutl1 mutant mice experienced retarded lung differentiation and abnormal hair follicle morphogenesis, indicating the vital role of CDP in lung development and hair follicle cell-lineage specification.

In this study, researchers developed a sensitive assay to measure the inhibition of steroid 5-α reductase (5AR) by chemicals like finasteride and dutasteride, revealing species-specific differences in inhibitor efficacy between human and fish cell lines.

This review discusses the potential benefits of using autologous endometrial cells and PRP via hysteroscopic injections to improve pregnancy outcomes in ART, particularly in individuals with refractory thin endometrium, but reports no new clinical results.

This study found that COVID-19 infection disrupts spermatogenesis, alters testicular cell populations, and may impact male fertility by causing long-term changes in testicular function and reduced sperm quality, as observed even in patients who have recovered from the acute phase of the infection.

This study discovered that in *Drosophila*, knockdown of specific storage proteins in adipocytes decreased germline stem cell maintenance, implicating a role for these proteins in adult tissue regulation.

In this study, researchers developed a novel computational framework using deep reinforcement learning to identify strategies for cellular reprogramming in gene regulatory networks, showing its effectiveness in a model of immune response against infection.

This study found that germ-free mice on a biotin-deficient diet exhibited significant weight loss and severe alopecia, unlike conventional mice on the same diet.

This study outlines new strategies for overcoming "cold" tumors, which are typically unresponsive to cancer immunotherapy, with approaches like dendritic cell-based treatments and local immune microenvironment modification, bolstered by both preclinical and clinical trial data.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This study found that IL-25-mediated-IL-17RB signaling improved diabetic wound healing by enhancing angiogenesis, collagen deposition, and endothelial cell function, suggesting a potential therapeutic strategy for poorly healing diabetic wounds.

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.
