This study found that macrophages treated with keratin in vitro were more similar to anti-inflammatory M2 macrophages and reduced astrocyte reactivity, potentially limiting secondary inflammatory damage after spinal cord injury.

This review discusses recent advances in scarless wound healing research, focusing on the roles of mechanobiology and immunology, and reports no new clinical results; the authors highlight the potential of next-generation human skin equivalents in understanding these mechanisms.

This review explores the role of macrophage subsets in adult cutaneous wound healing and emphasizes their potential for therapeutic targeting, but reports no new experimental results.

This case report describes a 7-year-old girl who developed radiation-induced alopecia after a neurointerventional procedure, with dermoscopy revealing specific hair and scalp patterns that helped diagnose this rare complication. The findings highlight the importance of dermoscopy in distinguishing RIA from other alopecic disorders in children.

The researchers reported that mesenchymal stem cells promote wound healing by using Cx43 hemichannels to mediate ATP secretion, which supports macrophage polarization, angiogenesis, and fibroblast migration, suggesting a potential therapeutic strategy for improving tissue repair.

This review discusses various techniques for treating post-acne scars, highlighting new laser technologies and tissue augmentation methods, but reports no new clinical results.

This study suggests that the tumescent technique effectively provides anesthesia and reduces bleeding during hair micrografting, eliminating the need for multiple needle injections or nerve blocks.

This article discusses the temporary scalp trichopigmentation procedure, detailing its unique approach compared to traditional scalp micropigmentation, and reports no new clinical findings.

In this retrospective analysis, researchers evaluated 54 patients undergoing soft tissue reconstruction for scalp and forehead defects and reported excellent aesthetic outcomes with local flaps for defects up to 50 cm², while larger defects typically required additional skin grafting.

This study observed that pediatric bone marrow transplantation patients frequently experience various dermatological issues; mucositis and xeroderma were the most common.

This study found that gelatin–polycaprolactone/silk fibroin composite membranes with line micropatterns enhanced wound healing in rats by promoting cell alignment, angiogenesis, and increased α-SMA production.

This study found that a high-energy shock wave can increase osteogenic activities in human mesenchymal cells, offering insights into potential therapeutic targets for trauma-induced heterotopic ossification.

This letter highlights concerns about transient lymphadenopathy as a potential adverse effect of platelet-rich plasma combined with microneedling for alopecia, emphasizing the need to understand its underlying cause.

Hair follicles in injured skin can quickly accumulate minerals, especially calcium and phosphorus.

This case report describes a 27-year-old male who developed a frontal scalp hematoma after platelet-rich plasma therapy and suggests that topical minoxidil may contribute to this side effect.

In this review, biomaterial-based mechanical strategies were highlighted for their potential to enhance skin regeneration and promote scarless repair, though a comprehensive understanding of their underlying mechanisms is still needed for broader application.

This study shows that multiphoton microscopy can non-invasively distinguish between scarring and non-scarring alopecia by identifying certain morphological features, but further research is needed to confirm its clinical utility.

This report describes three cases of white piedra of scalp hair, identifying Trichosporon inkin and Trichosporon mucoides as the fungi responsible, which are uncommon causes of this condition.

This study reviewed evidence on cutaneous reactions and associated radiation doses from cranial or spinal neurointerventional procedures, finding that alopecia/epilation was most common and onset doses often aligned with known thresholds, highlighting the need for standardized dose reporting and follow-up.

This study found that dermal stem cells from granulation tissue promoted wound healing and reduced fibrosis in a combined radiation and skin wound mouse model.

The authors reviewed cases of six children with both hair-shaft abnormalities and neurological disorders, noting that such hair defects may indicate neurological conditions, including potentially treatable metabolic errors.

This case report describes successful treatment of an 11-week-old infant with hair thread tourniquet syndrome causing toe swelling, highlighting the condition's rarity and the critical need for prompt surgical intervention.

This article illustrates various hair shaft defects and suggests that dermatologists can diagnose most of them using light microscopy and polarization without needing advanced imaging techniques.

This article reports on a family with six members diagnosed with monilethrix, highlighting varying degrees of alopecia linked to this rare hair shaft defect.

This review highlights the use of microneedling devices and patches to deliver cosmetic agents through the skin, noting their applications in skin rejuvenation and safety considerations such as potential skin irritation and infection.

This review discusses scalp micropigmentation techniques and their customization to individual patients, but reports no new clinical results.

This special issue reviews advancements in engineering cell microenvironments for tissue engineering, highlighting various studies on interventions like silk fibroin and platelet-rich plasma, but presents no new empirical findings.
