This study found that deleting the Twist1 gene in skin keratinocytes significantly reduced UVB-induced skin cancer and hyperproliferation in mice and suggested Twist1 as a target for skin cancer prevention.

This study found that IGF-1 injections increased hair follicle number and growth phase duration in wild-type mice, suggesting potential for baldness treatment.

This study found that far-infrared radiation preconditioning significantly enhanced the proliferation, survival, and migration of bone marrow-derived stem cells in vitro, indicating potential therapeutic benefits for cardiac ischemia treatment.

This study found that BMP6 and Wnt10b competitively regulate the transition between hair follicle growth phases, offering new insights into hair follicle cycling and potential hair loss treatments.

This study suggests that label-retaining cells in the hair follicle contribute to follicular renewal, indicating a specific role in the hair cycle by proliferating during the late telogen phase.

This article reviews mammalian skin epidermis as a model for studying stem cell regulation, noting the utility of in vitro and ex vivo platforms, but it reports no new empirical findings.

Skin-derived stem cells could help treat skin aging and pigmentation issues.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

This study found that a topical hedgehog agonist can stimulate hair growth by promoting the transition from the resting to growth phase of the hair cycle in adult mouse skin.

This review discusses the progress in identifying stem cells responsible for tissue regeneration and highlights technological advances in tracking their behavior, but reports no new clinical results.

This study found that β-catenin signaling increases in newly born glial cells in the cortex after traumatic brain injury in mice, suggesting potential targets for enhancing recovery through the Wnt/β-catenin pathway.

This study found that DNA strand segregation in multipotent hair follicle stem cells occurs randomly during development and tissue homeostasis, challenging the immortal strand hypothesis.

This review examines the location and markers of hair follicle stem cells, finding that they are primarily located in the bulge region and can contribute to various skin structures, but challenges remain in distinguishing them from their progeny.

In this animal study, topical minoxidil shortened the telogen phase of hair growth cycles in rats, suggesting it may stimulate certain follicles to progress more rapidly to anagen.

This study found that LED light irradiation induced proliferation and migration of human outer root sheath cells, potentially through the stimulation of the Wnt/β-catenin and ERK signaling pathways.

This study found that combining herbal extracts with PRP increased human dermal papilla cell proliferation via ERK and Akt protein regulation, suggesting its potential for developing hair growth therapies.

This study reported that disrupting ephrin-Eph interactions in adult mouse skin doubled cell proliferation in the hair follicle and epidermis, suggesting ephrins as negative regulators of proliferation.

This study found that Minoxidil had biphasic effects on normal human keratinocytes, stimulating proliferation at micromolar doses, but showing antiproliferative, pro-differentiative, and cytotoxic effects at millimolar concentrations.

This study found that the application of calreticulin significantly improved wound healing time and quality in diabetic mice, suggesting it may be an effective topical treatment for chronic wounds.

This study suggests that inactivation of β-catenin is necessary for chick retina regeneration, as it allows cells to enter the cell cycle during injury and promotes regeneration without needing FGF2.

This article explores questions about dormant hematopoietic stem cells and suggests avenues for future research, but does not present new experimental results.

This study found that melatonin's effect on HaCaT keratinocyte proliferation varied with concentration and incubation time, with no cytotoxic effects observed at suitable concentrations for skin treatment.

This study found that a topical cream containing PTH (7–34) significantly stimulated hair growth in hairless mice.

This study found that KLF4 expression in mouse hair follicle stem cells is important for effective cutaneous wound healing, with its knockdown leading to reduced stem cell populations and delayed healing.

This study found that follicular stem cells in hair follicles are more sensitive to the antiproliferative effects of glucocorticoids compared to basal keratinocytes due to incomplete desensitization.

This study found that topical cilostazol promotes hair growth, enhances hair follicle activities, and may serve as a potential treatment for alopecia.

This study found that human placental extract promoted hair growth and influenced cellular pathways in vitro and rat models, suggesting potential for future hair loss treatments.

This study found that MED1 deficiency in keratinocytes accelerates skin wound healing in young mice but delays healing in older mice, suggesting differential roles in epidermal regeneration with age.

In this study, sildenafil was found to enhance human dermal papilla cell proliferation and promote hair growth in mice, suggesting potential use in alopecia treatment.

In this study, the researchers found that the effectiveness of a 1,550-nm fractional laser in promoting hair growth in mice depends on the specific combination of beam energy and density, with inappropriate settings potentially causing ulcers or hair follicle injury.
