This protocol describes using two-photon laser-scanning microscopy to study hair regeneration in live mice, offering detailed imaging capabilities for observing hair follicle stem cell behavior and manipulating cellular populations.

This study introduces a new multimodal imaging technology to visualize and quantify cell dynamics in natural skin over long durations, demonstrated in GFP bone marrow-transplanted mice, to study dynamic skin regeneration.

This study introduces a five-modal microscopy technique that allows label-free, in vivo observation and quantitative analysis of various wound healing processes.

This study used two-photon microscopy to reveal that the dermal papilla is crucial for hair follicle regeneration and cannot be replaced by neighboring cells, providing new insights into stem cell behavior.

This study found that somatosensory axons innervating Merkel cells in adult mouse skin exhibit significant plasticity, influenced by epithelial and neural factors, indicating a complex interaction in maintaining homeostasis.

This study in adult mice found that somatosensory axons innervating Merkel cells in the skin are highly plastic, with significant remodeling in response to epithelial turnover, and that Merkel cells play a role in limiting axonal branching and promoting their maturation.

This study found that in adult mouse skin, somatosensory axon plasticity is highly dynamic and influenced by epithelial-neural crosstalk and intrinsic neural mechanisms.

In this study, researchers observed that different ERK signal activation dynamics during hair follicle regeneration are linked to cell fate specification and are affected by distinct upstream signaling pathways.

This study observed nestin-GFP expressing stem cells in the hair follicle bulge of living mice using high-resolution in-vivo multiphoton tomography, allowing migration tracking within their natural skin environment.

The conclusion is that the dermal papilla is crucial for hair follicle regrowth, and hair follicles undergo significant structural changes in addition to cell division during regeneration.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

This study concluded that intense pulsed light treatment effectively thinned hair to achieve a natural look after hairline correction surgery in East Asian women with naturally thick hair.

This study found that aminomethylpyrazole compound 10l inhibited hair growth in a mouse model and showed a low risk for photo-irritation, though it was slightly less effective than eflornithine.

This article presents two cases of positive outcomes using PRP for hair treatment but notes the lack of detailed protocols and longer follow-up, making it more a stimulative piece than conclusive evidence.

In this study, researchers found that black holes with primary Proca hair exhibit distinctive optical properties, including a two-boundary shadow structure and additional inner rings, offering novel observational signatures and potential insights into strong-gravity environments.

This study explored the use of an AI-driven device, HairMetrix, to quantitatively assess the effects of PRP treatments on scalp health in two Caucasian women with androgenetic alopecia, reporting increases in average hair width and follicle count after one treatment.

This study demonstrated that ablation of individual somatostatin-expressing interneurons increased activity in nearby neurons of the mouse motor cortex during motor learning.

This article presents a protocol for using mouse tail skin to study hair follicle stem cells, enabling visualization of calcium signaling and other cellular features in various conditions but reports no new research data.

This study found that multiphoton microscopy imaging allows for detailed observation and quantitative analysis of collagen alterations in the progression of endometrial cancer, potentially offering a faster, more accurate method for early diagnosis compared to current protocols.

This observational study reports that a TRASER device using specific wavelengths for vascular and follicular targets showed both clinical responses and histological changes, suggesting its potential as an effective vascular and hair removal tool.

This study found that combining red light therapy with oral beta-carotene significantly improved photoaging treatment outcomes compared to red light therapy alone, with Group A showing a 56.12% reduction in photoaging scores over 12 weeks versus 44.78% in Group B.

This study found that transtherapy, a treatment using Korean medicine, significantly improved acne scars, reducing the scarring grade from an average of 3.5 to 1.5 in moderate and severe cases.

This study evaluated the effects of pumpkin seed oil and rosemary essential oil combined with electrotherapy on androgenetic alopecia in stressed young women, finding no statistically significant differences between treatment groups and suggesting further research is needed to assess the oils' efficacy.
