This review summarizes the major events and regulators of the hair cycle in mammals but reports no new experimental results; it emphasizes the complex regulation of stem cell activation and differentiation during hair growth.

This review discusses the dual role of the Wnt/β-catenin pathway in mammalian tissue injury, highlighting its potential for both promoting regeneration and contributing to fibrosis, but presents no new findings.

This study expands knowledge of non-coding RNAs in goats and other mammals, enhancing understanding of their roles in hair follicle growth and regression.

This study highlights the loss of hair-type keratin genes in cetaceans compared to terrestrial mammals, suggesting a potential adaptive role linked to their hairless phenotype and habitat changes.

This review discusses the biological roles and diagnostic significance of keratins in mammalian colon epithelial cells and reports no new clinical results.

This review discusses the migration and colonization of melanocytes from the neural crest in mammals and reports no new experimental results.

This article explores the insights gained from using rat whiskers as a model for mammalian hair follicles and their implications for hair restoration surgery, without presenting new experimental results.

This study evaluated a new computer-aided detection system for identifying Breast Arterial Calcification in mammograms, achieving 70% accuracy, but highlighted the need for a larger dataset to explore its relationship with cardiovascular diseases.

This review found that vesicle-based therapies, including mammalian MSC-derived and plant-derived vesicles, consistently promote wound healing in preclinical models of thermal injury and may offer a safer alternative to live cell transplants.

This study found that RNase L acts as a regeneration repressor gene in mammals, as seen in Rnasel-/- mice which showed increased regenerative capacity and elevated Wound Induced Hair Neogenesis through enhanced IL-36α signaling, suggesting a tradeoff between regeneration and immune regulation.

This study suggests that incorporating matrisomal components into biomaterials could enhance skin wound healing in mammals that do not naturally regenerate tissues like the axolotl and Acomys.

This study found that MAPK/ERK signaling plays a key role in driving tissue regeneration in spiny mice and suggests potential for reversing fibrosis to promote regeneration in mammals.

This study found that the internal structure and fracture patterns of hair vary among different mammal species, which could inform the development of keratin-based biomaterials for medical and cosmetic applications.

This study found that guinea pig α-lactalbumin transgene was expressed in the mammary glands and sebaceous glands of transgenic mice, with milk protein production occurring in the expected secretory acini.

This review discusses the role of mitochondrial dysfunction in the ageing process and reports that its significance compared to other factors in mammalian ageing remains uncertain.

This study found that KSR1 is necessary for v-Ha-ras-mediated skin tumor formation but not for MT-driven mammary cancer, indicating its potential as a therapeutic target in Ras/MAPK signaling-related tumors.

This article reviews the similarities in early development processes of hair follicles, teeth, and mammary glands and reports no new experimental findings.

This study found that conserved DNA motifs and expression patterns in keratin genes suggest functional regulatory similarities in hair follicle differentiation across different mammalian species.

Cornification evolved from keratinization in vertebrates, with differences between mammals and sauropsids.

This study suggests that wounding skin in adult mice can trigger new hair follicle formation, indicating mammalian skin may have greater regenerative capacity than previously thought.

This study suggests that the keratins found in reptile and bird skin appendages evolved independently from mammalian hair keratins, highlighting convergent evolution in these species.

This research suggests that targeting the HIF-1α pathway via PHD inhibitors may enable regeneration similar to amphibians in mammals, potentially fast-tracking regenerative therapies from mice to humans.

This study suggests that NFIB and STAT5 work together to control cell-specific genetic programs in mammalian tissues, particularly in mammary and hair follicle stem cells.

In this study, researchers found that alpha-keratin homologs similar to those in mammalian hair are present in the claws of the lizard Anolis carolinensis, suggesting a structural role during claw formation.

This study reported that topical calcipotriol did not reduce hypertrophic scar formation in women post reduction mammoplasty, but found a strong association between activated keratinocytes and scar formation.

This study found that the tetrazolium salt INT is the most effective for revealing dehydrogenase activity and certain histological structures in sheep and other mammals' skin.

This study analyzes the fine structure and protein distribution in monotreme hairs, finding similarities with other mammals and detailing unique immunocytochemical features in their inner root sheaths.

This study identified Activin A and follistatin as key regulators of hair cell differentiation in the mammalian auditory sensory epithelium, with Activin A signaling influencing the timing and pattern of cell differentiation.

This study found that a new lecithinized coal tar formulation did not stain different types of mammalian hair, suggesting it may be promising for treating scalp psoriasis without the drawback of staining.

This study identified various cell types in the canine claw, showing complex mechanisms of cellular differentiation similar to mammalian hair and human nails.
