This study provides a comprehensive overview of human umbilical cord mesenchymal stem cell-derived extracellular vesicles (HUCMSC-EVs), suggesting their potential to combat aging and alleviate age-related disorders by rejuvenating multiple organs in animal models and discussing engineering strategies to harness their full anti-aging potential.

This study found that keratin 15 expression is downregulated in hyperproliferative conditions like psoriasis and hypertrophic scars, suggesting it is not compatible with keratinocyte activation.

This research review observed that topical hormone replacement therapy, particularly estradiol and estradiol-testosterone combinations, significantly increased Type I and III collagen synthesis in the skin of postmenopausal women, suggesting benefits against collagen loss-related skin aging effects such as reduced elasticity and increased dryness.

Hair follicle stem cells help maintain skin health after injury.

This study found that EGCG improved the integrity of skin grafts during cryopreservation, suggesting its potential usefulness for skin preservation, though the exact mechanism remains unclear.

Collagen XVIII is crucial for maintaining tissue structure and function in the brain, kidneys, and hair.

This study identified increased expression of ACAA1 and its regulation by hsa-miR-1343-3p, linking androgenetic alopecia to lipid metabolism pathways, particularly through PPAR signaling, in scalp tissues.

In this study, researchers using live mice observed that oncogenic Kras mutation disrupts hair follicle architecture by sustaining ERK signal activation, which affects stem cell behavior and tissue integrity.

In this study, researchers found that eccrine sweat glands in human scalp skin are morphologically integrated into the pilosebaceous unit, suggesting they form a common homeostatic tissue environment with adjacent structures.

This study found that matriptase, a membrane serine protease, is crucial for maintaining multiple types of epithelial tissues in mice, with its absence leading to severe organ dysfunction and increased permeability.

In diabetic mice, this study reported that the multifunctional hydrogel CPGel achieved complete wound closure in 21 days, showing promise in improving chronic wound healing through antibacterial, antioxidative, and tissue regeneration properties.

This paper reviews the state of knowledge on injectable cryogels, highlighting their unique properties such as shape-memory and mechanical integrity, which allow for minimally invasive delivery via needles and potential applications in oncology and regenerative medicine.

This integrative review concluded that microneedling therapy may be an effective and safe treatment for hair disorders like androgenetic alopecia, alopecia areata, and telogen effluvium, particularly when exacerbated by SARS-CoV-2 infection, offering promising results compared to other therapies.
