Mesenchymal stromal cell therapies show promise for treating various diseases but need more research and standardization.

In this case study, researchers observed reversible scalp hair loss associated with centrifugal lipodystrophy, potentially linked to altered leptin expression in inflamed adipose tissue.

This study used two-photon microscopy to reveal that the dermal papilla is crucial for hair follicle regeneration and cannot be replaced by neighboring cells, providing new insights into stem cell behavior.

This study found that while 3D spheroid culture preserved sweat gland cell-specific markers better than 2D culture, their growth and structural organization were suboptimal, highlighting the need for improved culture systems.

This study found that skin fibroblasts in mice arise from two distinct lineages which contribute differently to dermal structure and repair, impacting hair follicle formation during wound healing.

This review updates the understanding of fibroblast heterogeneity in wound healing, discussing advancements in fibroblast roles and potential therapies, but it reports no new clinical results.

In this study, using stirred-suspension bioreactors to expand dermal stem cells resulted in larger numbers, but had reduced efficiency in forming hair follicle structures compared to static culture conditions.

This study found that transplanting adipose tissue into the rat dorsum supported long-term skin expansion by enhancing thickness, vascularization, and cell proliferation, with adipose-derived cells actively contributing to skin regeneration and growth factor expression.

This report expands the known genetic mutations linked to monilethrix by identifying new patients with KRT83 mutations, confirming its role as a causative gene for this hair disorder.

This review highlights how intravital microscopy has advanced understanding of tissue homeostasis and cancer progression, focusing on how tumor cells exploit physiological processes for growth; it reports no new experimental findings.

This article reviews the genetic foundations of keratins in maintaining epithelial tissue integrity and links specific keratin variants to diverse ichthyosis forms, without presenting new clinical findings.

This study observed that after hair cell loss in the mouse cochlea, supporting cells were replaced by migrating non-specialised cells, with genetic background affecting the rate of tissue re-organization.

In this study, researchers found that the JAK1/2 inhibitor ruxolitinib helped normalize tissue-specific autoimmunity in APECED patients by reducing inflammation and immune cell accumulation, but it was also linked to subclinical side effects like anemia and weight gain.

This article discusses the factors involved in optimizing laser hair removal, emphasizing patient selection, laser safety, and understanding laser–tissue interactions, but presents no new clinical findings.

This study found that over-expressing Spry4 and Fgf10 modulates feather stem cells to alter feather morphologies in distinct ways, affecting barb branch formation and tissue structure.

In this study, researchers engineered ventral skin organoids (vSkOs) with specific cellular compositions and signaling environments to generate human amnion-like tissues called Amnioids, offering new tools for studying human development and potential regenerative therapies.

This review discusses the use of trichoscopy for diagnosing systemic diseases and concludes that certain trichoscopic features may help dermatologists suspect these conditions.

This review discusses the historical development and dermatological applications of platelet-rich plasma, emphasizing its potential for treating androgenic alopecia and other skin conditions, but reports no new clinical results.

This study highlights that while advances in dermatology, such as biologics and JAK inhibitors, have improved treatments for conditions like atopic dermatitis and psoriasis, challenges remain, including issues with lasting efficacy and the need for more personalized therapies.

This study found that Cathepsin E plays a crucial role in keratinocyte terminal differentiation, affecting epidermis formation and homeostasis in mice.

This study created a detailed spatial atlas of healthy human skin and basal cell carcinoma, revealing a potential hair follicle origin for basal cell carcinoma and expansion of certain mesenchymal cell populations.

Oral and maxillofacial surgeons are now well-equipped to offer comprehensive facial cosmetic care after additional training.

This review discusses strategies and advances in bioprinting for skin wound healing, concluding that bioprinting could offer promising solutions for skin regeneration despite existing challenges.

This study found that dermal fibroblast cultures, especially those with higher alpha-smooth muscle actin expression, can be used to produce skin-derived precursor cells, unlike human hair follicle dermal papilla cultures.

This review discusses the role of activin signaling in hair follicle formation, hair growth cycling, and skin healing, but presents no new clinical findings.

This study identified lymphatic vessels as crucial components of the hair follicle stem cell niche, coordinating connections and contributing to hair follicle regeneration in mice.

This review discusses the role of the sonic hedgehog pathway in skin development and cancer, highlighting its potential as a target for chemoprevention and treatment; it reports no new findings.

The authors concluded that using an expanded temporoparieto-occipital scalp flap for sideburn reconstruction provides satisfactory hair direction and inconspicuous scars in both the donor and recipient areas, with few complications.

This study found that prolonged acute tissue expansion notably increased the amount of scalp tissue removed during scalp reduction surgery in three patients.

This study reports that using a combined approach of free osteoseptocutaneous fibula flap and temporal artery-based scalp flap provided satisfactory aesthetic and functional outcomes in reconstructing gunshot-inflicted composite mandibular defects in males.
