This review highlights the potential of cell-free therapies, particularly cell extracts, in addressing radiation-induced salivary gland damage from head and neck cancer treatment, emphasizing their practicality and safety compared to traditional therapies despite incomplete understanding of their bioactive components.

This study found that humans have a significantly slower wound-healing rate compared to non-human primates and other animals, suggesting that slow wound healing is a characteristic unique to humans within the primate order and potentially indicating evolutionary adaptations.

This review highlights that current in vitro models often fail to replicate the physiological oxygen levels experienced by different skin cell types, which could affect redox states and functions, potentially accelerating skin aging.

This scoping review evaluates the connection between hypoxia and declining sex hormonal signaling in middle-aged individuals, proposing a "middle-aging hypovascularity hypoxia hypothesis" as a potential mechanism influencing age-related diseases, with implications for developing strategies to maintain healthspan.

This case report describes a rare instance of a Chinese Crested dog with leukocyte chimerism, normal female external genitalia, and hormonally active Sertoli cell tumors, demonstrating surgery as a curative treatment option.

This review discusses the role of metabolism in maintaining adult stem cell homeostasis with aging and highlights the potential benefits of dietary restrictions on stem cell function and longevity. It reports no new clinical results and emphasizes the need for further molecular studies.

In this study, researchers found that Wnt4 overexpression increased the thickness of burn wounds by promoting epidermal cell migration and activating the canonical Wnt signaling pathway.

This study found that keratin 15 lacks the ability to sequester YAP1 in keratinocytes effectively, unlike keratin 14, and suggests that a higher K15:K14 ratio may promote a progenitor state and inhibit differentiation in epidermal keratinocytes.

In this study, researchers used single-cell RNA sequencing to identify cell types and molecular differences in subcutaneous adipose tissue from various anatomical sites, suggesting that certain subpopulations of human adipose stem cells might improve the treatment of chronic refractory wounds.

This review synthesizes current advances in transcriptomics and RNA regulatory networks, alongside stem cell-derived skin organoid research, to propose a conceptual framework for understanding and potentially guiding regenerative skin repair, without claiming clinical readiness.

This study highlights that a novel radially aligned nanofiber scaffold with dual growth factor gradients significantly enhances wound healing, promoting cell migration, epidermal regeneration, and angiogenesis, ultimately leading to improved wound closure, immune regulation, and tissue remodeling compared to other groups.

This study suggests that supplementing with a cell-free fat extract might enhance embryo development and improve clinical outcomes in older women experiencing in vitro fertilization failure.

This study found that different epidermal stem cell populations contribute to the formation of various skin tumors and new hair follicles following β-catenin activation in the adult epidermis.
