This review discusses the regenerative potential of polynucleotides and polydeoxyribonucleotides in aesthetic medicine, noting their benefits for skin texture, hydration, and patient satisfaction despite limited high-quality evidence.

The hydrogel helps heal wounds without scars by releasing two drugs gradually.

This study reviews the role of exosomes in regenerative aesthetics, highlighting their potential in treating conditions like photoaging and wound healing through mechanisms like matrix remodeling and immunomodulation, while also noting advancements in exosome isolation techniques and regulatory considerations.

In this study, a new topical formulation containing amine-activated carboxymethyl chitosan and hydrolyzed extracellular matrix showed promising results in a mouse model by reducing oxidative stress, inflammation, and promoting hair regeneration, potentially offering an alternative treatment for inflammatory hair loss.

This review highlights single-cell sequencing's role in understanding macrophages' diverse functions and subtypes in skin wound healing, emphasizing macrophages' importance in tissue restoration and identifying key genes involved in the process.

This study found that human dermal papilla cells are surrounded by a basement membrane-like extracellular matrix, which maintains their aggregated structure without strong cell‒cell contacts.

This review highlights PRF's potential as a regenerative medicine tool, detailing its diverse applications in dentistry, orthopedics, and dermatology, but presents no new clinical results.

This study found that upper-bulge epidermal stem cells in mouse hair follicles are specialized for nerve interactions, crucial for forming tactile sensory units, and influence touch responses via EGFL6 and αv integrin pathways.

This study found that culturing hair follicles at the air-liquid interface enhanced hair growth and maintained an anagen-like morphology better than submerged cultures.

This article discusses the potential use of human hair follicular stem cells combined with platelet-rich plasma for androgenetic alopecia, focusing on the regenerative processes involved, but reports no new clinical results.

This study found that topical application of 17 alpha-propylmesterolone significantly increased proliferative activity in hair matrix cells in men with androgenetic alopecia.

The study identified increased IL-24 expression in keratinocytes and fibroblasts exposed to particulate matter, contributing to skin aging by promoting conditions similar to age-related changes such as increased MMP1 expression and decreased type I collagen production.

This review discusses the potential of single cell technologies to improve understanding and treatment of impaired wound healing and reports no new clinical results.

This chapter reviews therapies for skin and corneal regeneration and hair loss, discussing various treatments but presenting no new research findings.

This review examines the challenges of cell engraftment in regenerative medicine and discusses potential strategies to improve the efficacy of cell-based therapies, including cell-free regenerative approaches.

This review discusses key molecular targets in cosmetic research and reports no clinical results; it highlights the role of telomerase, sirtuins, and tyrosinase in anti-aging and depigmentation strategies.

In this study, a spayed adult female dog with recurrent vaginitis and cystitis due to bone structures in the vaginal canal was successfully treated with manual removal and medication.

This study found that newborn mouse skin organoids can robustly grow hair in vivo, while adult organoids require specific interventions to restore their hair-forming ability.

This study re-examined the structure of lanceolate endings in rat vibrissae, suggesting that their apical cones may function as a transducer site for detecting hair movements.

This study presents a method using polarization-sensitive optical coherence tomography to accurately assess the depth of burn wound damage in the dermal collagen matrix, potentially improving diagnosis beyond traditional visual methods.

This study identified upregulation of genes linked to fibroproliferative disorders, such as platelet-derived growth factor and collagen genes, in patients with central centrifugal cicatricial alopecia, suggesting potential therapeutic targets.

This study observed that aging leads to significant structural and biological changes in the scalp's hair follicle environment in women, which may affect hair growth.

This review discusses recent advancements and ongoing challenges in engineering human skin with appendages using scaffold-free and scaffold-based bioengineering approaches, but it reports no new clinical results.

This study found that hydro-alcoholic Eclipta alba extract may have anticancer and multidrug resistance-reversal effects in animal models, suggesting potential as an adjunctive agent in tumor chemotherapy.

This study found that suppressing Jagged1 in epidermal stem cells disrupted Notch signaling and resulted in poor-quality wound healing, suggesting a potential therapeutic target for improving wound repair.

This study found that epithelial components of calcifying epithelioma of Malherbe showed lectin binding and keratin staining patterns similar to normal hair follicles, with prominent Con A staining in tumor giant cells.

In this study using a rat full-thickness burn model, the amnion bilayer dressing showed better healing and skin recovery than the standard protocol, including quicker complete healing and restored skin appendages.

This study observed that treating hair follicles with BM15766 and 7DHC led to structural damage, disrupted cellular organization, reduced expression of key genes and proteins, and increased apoptosis, in contrast to controls, indicating detrimental effects on hair follicle integrity.

Monocyte-derived dendritic cells play a key role in UVB-induced skin sensitivity and inflammation.

This study found that ageing in women leads to significant structural and biological changes in the scalp hair follicle environment, which may affect hair growth.
