This study found that cathepsin L deficiency in mice led to significant abnormalities in hair follicle development and cycling, including disrupted hair shaft outgrowth and premature hair growth phase entry.

This study found that mice lacking the 1αOHase enzyme, which is responsible for producing a key vitamin D metabolite, showed impaired epidermal differentiation and delayed recovery of skin barrier function after disruption.

This review outlines the advancements in organ and tissue transplantation since the discovery of the human MHC and reports no new clinical results.

This study found that overexpressing Dsg3 in the suprabasal epidermis of transgenic mice resulted in flaking skin and abnormal hair growth, supporting Dsg3's role in regulating epidermal differentiation.

This study found that human hair follicle-derived mesenchymal stem cells can differentiate into myogenic, osteogenic, adipogenic, and chondrogenic lineages, although this potential decreases over time and varies by lineage.

This review summarizes recent findings on how Wnt signaling proteins play crucial roles in the cutaneous wound healing process but reports no new clinical results.

This study suggests that mesenchymal stem cell-induced dermal papilla-like tissues can generate new hair follicles in mice, indicating potential for developing hair cell therapy using stem cells.

Bone-marrow and epidermal stem cells help heal wounds differently, with bone-marrow cells aiding in blood vessel formation and epidermal cells in hair growth.

This study observed that CIP/KIP proteins play a significant role in regulating cell cycle arrest and differentiation in human hair follicles, supporting hair growth and formation in the anagen phase.

This study found that overexpression of the transcription factor NFIC may enhance the proliferation and differentiation of stem cells from the apical papilla, suggesting its potential role in dentin/root regeneration.

This study found that upregulation of NFIC may enhance proliferation and osteogenic/cementogenic differentiation in rat dental follicle cells.

This study found no difference in bone mineral density between young women with PCOS and age- and BMI-matched controls, but BMI significantly influenced BMD in women with PCOS.

This study demonstrates that Rac1 activity is essential for normal hair follicle formation but influences hair structure and pigmentation, in terminal differentiation, through alterations in hair shaft, cuticle, and pigmentation organization.

This study found that a mutation causing Stormorken syndrome in mice led to skeletal abnormalities and unusual hair growth, showcasing the STIM1 R304W protein’s role in bone development and cell fate.

This study demonstrated that human dermal mesenchymal stem cells can be differentiated into cardiomyocytes using 5-azacytidine, suggesting potential future applications for treating myocardial infarction.

This study found that overexpression of sPLA2-IIA in homozygous mice resulted in cyclic alopecia, a halt in hair follicle cycling, and impaired wound healing due to complete loss of hair follicle stem cells.

This study found that dermal EZH2 plays a crucial role in controlling fibroblast differentiation by regulating Wnt/β-catenin and retinoic acid signaling during skin development.

In this study, adipose-derived stem cells from human scalp were successfully directed towards chondrocyte differentiation, with TGF-beta3 and BMP-6 growth factors proving effective for in vitro chondrogenesis.

This study found that Wnt5a expression may suppress cell differentiation and induce an inflammatory response in HaCaT keratinocytes, which could be relevant to psoriasis development.

This study found that patients with hidradenitis suppurativa had lower trabecular bone score and total hip bone mineral density compared to controls, with a high prevalence of vitamin D deficiency.

In this study, low-level laser therapy significantly improved the mechanical strength of bone at tooth extraction sites in rats, while neither platelet-rich plasma alone nor combined with laser affected mechanical strength or calcium content.

This study found that gelatin sponges used as scaffolds in rats with deep wounds and periosteal defects enabled regeneration of diverse tissue types, including periosteum, skin, and appendages, highlighting the role of vascular niche formation.

This case report describes a Japanese bone marrow transplant recipient who developed a high-risk cutaneous squamous cell carcinoma on the scalp, potentially linked to long-term voriconazole use.

This study found that Erdr1 expression was significantly reduced in the skin of patients with hair loss disorders, particularly alopecia areata, suggesting it may serve as a novel biomarker.

This review discusses mesenchymal stem cells' role in tissue regeneration and skin anti-aging, highlighting their migration to damaged sites and secretome effects, but reports no new clinical results.

This review summarizes discussions from a 2010 stem cell biology meeting, covering the origin, behavior, and therapeutic potential of pluripotent and multipotent stem cells, without reporting new experimental findings.

This research reviews the scientific literature on bone broth extract, exploring its nutritional composition, potential health benefits, food industry applications, and risks such as heavy metal and antibiotic contamination. Results are not reported in this summary.

This study found that VEGFR-2 activation may play a role in hair follicle differentiation, proliferation, and apoptosis by co-expressing with several key proteins in normal human scalp skin.

In this study, mouse hair follicle stem cells cultured in mouse embryonic fibroblast/keratinocyte serum-free medium exhibited the highest proliferative ability and stronger osteogenic differentiation potential, similar to hair follicle dermal papilla cells.

The study found that dermal EZH2 plays a crucial role in coordinating dermal fibroblast differentiation and epidermal development by modulating Wnt/β-catenin and retinoic acid signaling.
