This study found that testosterone therapy improved physical performance and strength in older men with low testosterone over 36 months, whether administered alone or with finasteride.

This study found that testosterone therapy increased bone mineral density in older men with low testosterone, and combining it with finasteride may reduce prostate enlargement associated with testosterone treatment.

This study found that encapsulating hADSCs-derived exosomes in PF-127 hydrogel improved wound healing in mice, suggesting a promising approach for enhancing skin repair.

This review synthesizes recent research on exosomes, highlighting their role as key modulators in regenerative outcomes and suggesting they may offer advantages over stem cell-based therapies in process and regulation.

This study found that exosome-incorporated human amniotic membrane scaffolds notably enhanced diabetic skin wound healing in mice, suggesting potential applications for ADSC-derived exosomes in clinical settings.

This study identified a distinct "exogen" phase in the hair cycle during which hair shedding occurs, primarily coupled with the anagen phase, rather than as part of the telogen phase.

In this study, dermal papilla cell-derived exosomes accelerated hair follicle growth in mice, suggesting potential for treating hair loss by modulating key signaling pathways.

This review discusses the shedding phase of the hair cycle, known as exogen, and reports no new findings while analyzing related processes like club fiber formation and release.

This study found that testosterone replacement, with or without finasteride, did not lead to significant cognitive improvements over 36 months in healthy older men without prior cognitive impairment.

This review discusses recent advances in the therapeutic potential of exosomes for wound healing, highlighting their benefits and challenges but reports no new clinical results.

This study proposes the miR-22-5p-LEF1 axis as a novel pathway that may regulate hair follicle stem cell proliferation.

Dermal exosomes with miR-218-5p boost hair growth by controlling β-catenin signaling.

This study suggests that exosomes derived from dermal papilla cells, especially those cultured in three dimensions, promote hair growth and regeneration by enhancing follicular cell activity.

This study found that IGF-1 injections increased hair follicle number and growth phase duration in wild-type mice, suggesting potential for baldness treatment.

Exosomes are crucial for protecting sensory hair cells in the inner ear.

This review discusses the potential of endogenic and exogenous exosomes in dermatology and cutaneous aesthetics, highlighting their capacity to repair and rejuvenate skin tissue, but reports no new experimental results.

This review examines the potential of plant-derived exosome-like nanovesicles in dermatology, highlighting their bioactive properties and discussing challenges to their clinical application, but does not provide new clinical results.

This study found that MDSC exosomes promoted partial hair regrowth and modulated immune responses in mice with alopecia areata, suggesting potential as a treatment for autoimmune diseases.

This review discusses the potential role of mesenchymal stromal cell-derived exosomes in skin regeneration and calls for more research to address clinical translation challenges, without reporting new results.

In an animal model, this study found that PEG hydrogels delivering M2 macrophage-derived exosomes effectively promoted M1 to M2 macrophage transition and enhanced wound healing.

In this study, researchers developed a non-invasive method to distinguish exogen hair from telogen hair on the human scalp, finding that normal exogen hair levels are generally less than seven hairs per cm².

This study found that exogenous ochronosis from hydroquinone use in melasma treatment has distinctive dermatoscopic features that may aid in diagnosis without needing a biopsy.

This study found that the outer protein layer of Merino wool is rich in sulfur-containing proteins similar to those found in both sheep wool and human hair.

This study found that the application of calreticulin significantly improved wound healing time and quality in diabetic mice, suggesting it may be an effective topical treatment for chronic wounds.

This study found that exosomes from different mesenchymal stem cell sources had distinct effects on immune cell functions and varied microRNA expression profiles compared to their original cells.

This study found that exosomal miR-181a-5p promotes hair follicle growth and development in vitro by activating the Wnt/β-catenin signaling pathway and suppressing hair follicle stem cell apoptosis.

This review discusses the potential of mesenchymal stem/stromal cells and their exosomes in promoting wound healing and skin regeneration, but reports no new experimental results.
