This report discusses a potentially underdiagnosed form of multisystem Langerhans cell histiocytosis in infants, demonstrating the use of thymic sonography for staging, highlighting a case where thymic and cutaneous involvement was confirmed, and suggesting thymic ultrasound may aid in better diagnosis and management of LCH.

This article discusses the development of the regenerative medicine field based on stem cells' capacity for in vitro differentiation, rather than actual organ or tissue regeneration.

This study found that innate lymphoid cells-type 1 (ILC1lc) can induce alopecia areata (AA) by disrupting hair follicle immune privilege and causing hair follicle dystrophy and regression in both ex vivo and in vivo settings.

This study found that the Arabidopsis cation chloride cotransporter (CCC1) is crucial for regulating pH and processes in the trans-Golgi-network/early endosome, impacting plant growth and stress responses.

The research found that while Dnmt3a and Dnmt3b are not necessary for skin homeostasis in mice, the loss of Dnmt3a increases squamous tumor formation from carcinogens, and combined deletion of both results in more aggressive and metastatic tumors.

This study found that a transcription factor called FoxA is specifically required for the regeneration of the planarian pharynx, suggesting its critical role in organ-specific regeneration.

Substance P helps restore skin thickness and cell renewal when sensory nerves are reduced.

This study found that Brazilian patients with advanced NSCLC required significant survival gains to accept treatments causing severe tiredness or skin rash, with preferences varying among treatment options.

This study developed the iCOUNT tool, which provides insights into stem cell behavior by tracking cell division events and molecular consequences in human and mouse neural stem/progenitor cells.

In this study, the researchers found that depleting natural polyamines or manipulating translation rates can enhance the stemness of hair follicle stem cells, while N1-acetylspermidine increases proliferation without affecting translation.

This review discusses the significant role of Wnt signaling in skin development, homeostasis, and disease, highlighting recent advances in understanding its diverse functions, but reports no new experimental results.

This study found that Notch signalling promotes differentiation of epidermal cells and acts as a tumour suppressor in the skin by interacting with various pathways and mechanisms.

This discussion explores advances in intravital imaging for visualizing stem cells, highlighting key discoveries and potential future developments; it reports no new experimental results.

This review discusses the potential regulation of signal transduction pathways by microRNAs in animal cells, aiming to identify biological processes that may be influenced by miRNA-mediated regulation, but it reports no new experimental outcomes.

This review summarizes how genetic studies using conditional β-catenin loss- and gain-of-function mice have advanced understanding of canonical Wnt signaling's role in embryonic development, adult stem cell maintenance, and cancer modeling.

This review explores the mechanisms of adult stem cell self-renewal, using skin as a model, and reports no new results but raises important unanswered questions in the field.

This study found that androgen receptor activation in adult mouse skin reduces β-catenin-induced hair follicle growth and sebaceous gland conversion, highlighting its role in stem cell fate decisions.

This study found that a young male Maine Coon cat with a tortoiseshell coat, which typically indicates unusual sex chromosomes, was fertile, carrying both XX and XY cell lines. The researchers recommend genetic testing for tri-colored male cats before breeding decisions.

This review discusses the Activin/Nodal signalling pathway's role in stem cell function and its implications in cancer therapy, reporting no new experimental results but highlighting future research questions.

This study demonstrates that modeling clone size independently of time offers analytical advantages for understanding cell distribution and mutation frequency in epithelial progenitors, extending applications beyond neutral models.

This study found that Cannabidivarin (CBDV) promotes neuronal differentiation and inhibits oligodendrocyte maturation via TRPV1 modulation, highlighting its potential in neural stem cell research.

This mini-review explores how both endogenous and damage-released RNAs serve as instructional signals that influence cell identity and plasticity during tissue maintenance and repair, highlighting RNA's role as a regulator of cellular flexibility in various regenerative contexts.

This study suggests that mouse lineage specification during pre-implantation development involves distinct timing and mechanisms for trophectoderm and inner cell mass differentiation, challenging existing models.

This study revealed that hair cells undergo an organized process to become keratin-packed "zombie" cells, highlighting a key area for treatment development in the first 1mm of hair follicles.

This article discusses the discontinuation of the Bexxar regimen for non-Hodgkin's lymphoma, noting that despite its effectiveness, it was under-prescribed due to marketing and development challenges without reporting new clinical results.

This article discusses developments in clinical urology featured in the Journal of Urology's October 1999 issue and presents no new clinical findings.

The committee unanimously voted against recommending approval of the injectable cisplatin/epinephrine gel IntraDose for certain head and neck cancer patients, citing insufficient clinical benefit and concerns about toxicity in this study.

MRI helps distinguish between pituitary adenomas and craniopharyngiomas, guides treatment for pediatric CNS tumors, and assesses rhinocerebral mucormycosis with a high mortality rate in transplanted patients.

In a randomized clinical trial, Robinson et al found that patients with melanoma and their partners could effectively perform skin self-examinations after participating in a 30-minute structured skills training, potentially aiding early detection of additional melanomas.

The editorial concludes that while evidence-based medicine is crucial, doctors should also use their own experience and consider patient preferences in dermatology care.
