In this study, mice exposed to prolonged space conditions demonstrated skin atrophy, altered hair follicle cycles, and significant changes in the gene expression associated with skin muscle health.

This study identified chemokine receptor ligands cxcl10 and cxcl11 as new hair-specific transcriptional targets of the Eda pathway, suggesting chemokine signaling plays a role in primary hair follicle patterning.

This review discusses the effects of valproic acid on immune cell activation and gene expression, potentially influencing infection outcomes and suggesting its promise for autoimmune and hypersensitivity condition management.

This review discusses the role of pharmacological sciences in advancing regenerative medicine technologies but reports no new experimental findings; the authors advocate for increased pharmacologist involvement to drive innovations.

In this study, decreased expression of BMP2 and ephrin A3 and increased NT-4 gene expression were observed in dermal papilla cells from androgenic alopecia-affected skin, suggesting potential roles in hair growth regulation.

This study found that lymphatic vessels in mice are important for hair follicle development and organization, as their depletion blocks hair growth.

This study suggests that TGF-β 2 plays a critical role in hair follicle morphogenesis and may enhance the effectiveness of future cell therapies for hair regrowth using expanded dermal papilla cells.

This review explores the potential (neuro-)endocrine influences on hair follicle epithelial stem cell biology and emphasizes the need for more systematic research, but it provides no new empirical results.

This review discusses the progress in tooth regeneration research and highlights the potential of spatial-temporal release of developmental factors, but it reports no new clinical findings.

The authors describe drug repurposing as a promising strategy for finding new uses for existing drugs, noting it is efficient, cost-effective, and poses lower risks than traditional drug discovery processes, potentially aiding in the treatment of rare and difficult-to-treat diseases.

This study's meta-analysis reported that PRP injections significantly increased hair density compared to baseline and placebo in androgenetic alopecia patients, supporting its use as a beneficial treatment.

This review discusses the potential of repeated low-level red-light therapy to inhibit myopia progression through metabolic effects, highlighting its molecular and cellular impact, but reports no new clinical results.

This review examines how fibroblasts contribute to regeneration in various organs and explores the potential of reverting adult fibroblasts to a fetal-like state for regenerative therapies, but reports no new empirical findings.

In this study, epidermal Notch activation increased jagged 1 expression, leading to skin changes like thickening and blistering, with these effects inhibited when jagged 1 was absent.

This review discusses the dual role of cellular senescence in ageing and tissue repair and suggests potential therapeutic applications, with no new experimental results reported.

In this study, researchers found that alkylating chemotherapy causes hair follicle stem cells to lose their regenerative ability by initially triggering proliferation followed by apoptosis, leading to permanent regeneration loss.
