This overview highlights the exploration of mesenchymal stromal cells as potential treatments for COVID-19, noting their regenerative and immunomodulatory properties for reducing ARDS severity in critically ill patients, but it provides no new clinical results.

This review discusses how recent studies use models and experiments to understand immune system signaling, but it reports no new clinical findings; the authors suggest strategies for improving these models.

This review discusses the potential mechanisms of platelet-rich plasma in facial rejuvenation and reports no new clinical results, indicating a theoretical basis for its use in tissue regeneration.

This study found that 5% primed conditioned medium from human umbilical cord blood-derived mesenchymal stromal cells significantly improved hair density, thickness, and growth rate in patients with androgenetic alopecia.

This study found that deletion of c-Jun and JunB in mouse bulge hair follicle stem cells was sufficient to trigger psoriasis-like skin disease through thymic stromal lymphopoietin signaling.

This review highlights that the NLRP3 inflammasome is a promising therapeutic target for cerebral ischemia-reperfusion injury and discusses recent advancements in using natural plant products to modulate this pathway and reduce inflammation.

This review discusses how inflammation influences hair follicle stem cell activities like wound healing and follicle cycling and suggests a potential link between inflammation, stem cell activation, and programmed cell death.

This study found that Th17 lymphocytes may play a more crucial role than cytotoxic T cells in the development of alopecia areata due to their infiltration around the hair bulb/bulge, which exacerbates hair loss as histopathological grade worsens.

This review examines non-invasive methods for diagnosing inflammatory skin diseases like lupus erythematosus and psoriatic inflammation using samples from plucked hair and skin tape-strips, but no new clinical results are presented.

This study identified a regulatory element necessary for Foxn1 expression specifically in mouse thymic epithelial cells, crucial for thymus development but not affecting hair follicles.

This study demonstrated that customized microneedle arrays can precisely induce targeted hair regeneration and improve hair quality in mice, potentially offering a personalized treatment approach for hair loss.

This study observed that carboxytherapy significantly improved clinical and dermoscopic measures in patients with alopecia areata and androgenetic alopecia compared to placebo, though some benefits regressed during follow-up.

This study found that over- and ectopic-expression of FoxN1 in early life negatively affected the development of thymic epithelial cells, T and B cells, and skin epithelial cells.

This study found that mammary resident macrophages play a key role in mammary tissue development by influencing cell division and maintaining mammary stem cell activity through the TNF-α-Cdk1/Cyclin B1 signaling pathway, highlighting their importance in the mammary stem cell niche.

This study used single-cell RNA sequencing to create a detailed atlas of human scalp hair follicles and found that early-stage hair graying involves matrix hair progenitor depletion linked to P53 pathway activation.

This review explores the expression of Perforin by gamma delta T cells in human skin and its role in cytotoxicity but reports no new experimental results.

This study found that the expression of laminin-511 and -332 was significantly increased in psoriasis skin lesions and may influence keratinocyte proliferation and apoptosis, suggesting a previously overlooked role in the disease's pathogenesis.

This study found that diphencyprone showed a significant clinical response for treating alopecia areata, while tacrolimus was not effective.

This study found that metabolism-related genes significantly impact the prognosis and metastasis in breast cancer, and the development of prediction models may guide personalized therapeutic strategies.

This study found that mixtures used in permanent hair dyes had irritant effects on reconstructed human epidermis, while individual ingredients alone did not.

In this study, researchers using the hair paradigm highlighted how periodic patterning and compartmentalization enable diverse regenerative behaviors, including region-specific renewal cycles and emergent properties like regenerative waves in organ populations.

This study found that immune cells, including T cells and macrophages, significantly influence stem cell behavior and tissue regeneration by secreting cytokines and inflammatory factors in mice.

This study reports that immunologically inert and skewed immune cell populations in developing human skin may contribute to wound healing and structural changes during skin development.

In this study, basal cell carcinoma developed in Ptch-deficient mice only after chemical treatment, not skin wounding, suggesting a second unknown event is necessary for tumor formation.

In this study, topical quercetin was found to stimulate hair follicle growth and promote microvascular regrowth in mice, suggesting its potential for hair regrowth strategies.

This study suggests that mammalian hair follicles may serve as a viable and non-invasive system for diagnosing traumatic brain injury, reflecting similar molecular responses observed in other tissues.

This review discusses the role of fibroblast heterogeneity in kidney pathology, particularly their contribution to tertiary lymphoid tissue formation, and reports no new results.

This study found that M30 may protect against cyclophosphamide-induced alopecia in mice by enhancing hair growth and preventing abnormal hair, suggesting its potential as a treatment.

This review discusses insights from scar-free animal models and cellular factors in skin regeneration, suggesting potential strategies for developing scar-free treatments in clinical and cosmetic practices, but reports no new clinical results.

This study found that carbonic anhydrase II was significantly upregulated in human keratinocytes when treated with toll-like receptor 3 agonist and Th2 cytokines, suggesting its potential role in inflammatory skin conditions.
