This review discusses the role of perifollicular macrophages in hair growth and suggests targeting them could be relevant for managing hair growth disorders, but reports no new results.

This review discusses recent advancements in regenerative medicine, including functional organ regeneration and the creation of mini-organs, and reports no new clinical results.

This review describes the development of three mouse models using fluorescent proteins to visualize and study angiogenesis in tumors, particularly detailing interactions between tumor cells and the surrounding stroma.

This study found that angiogenin is expressed in human dermal papilla cells, where it might stimulate hair growth by promoting cell proliferation and local skin angiogenesis.

This study found that transplantation of autologous stromal vascular fraction cells increased skin thickness and improved regeneration when combined with mechanical stretching, without severe adverse events.

This study suggests that thymosin beta 4 may regulate hair growth by influencing VEGF and MMP-2 levels through the Wnt/β-catenin/Lef-1 signaling pathway in mouse models.

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.

This study found that CD34+ cells from adipose tissue may enhance hair morphogenesis and participate in blood vessel formation in reconstituted skin tissues of mice.

Vitamin B12 deficiency can cause skin darkening and increased blood vessels, but treatment can improve symptoms.

This study found that SA-MS hydrogel released Mo4+ ions which promoted healing of disease-impaired wounds by enhancing cell proliferation and angiogenesis, and through its photothermal effects addressed skin cancer-impaired wounds in mice.

In this study, severe diffuse hair loss in patients with systemic lupus erythematosus was associated with distinct clinical, dermoscopic, and histopathological features, which improved alongside treatment of the underlying condition.

This study found that telocytes in human scalp tissue were located around hair follicles and glands and may be involved in skin regeneration and homeostasis.

This paper proposes a new hypothesis that androgenic hair loss may be caused by changes in scalp vasculature due to androgen effects, but reports no new experimental results.

This research reported that melatonin may serve as a potential treatment for both rosacea and Alzheimer's disease by regulating inflammation and vascular signaling pathways, demonstrating effectiveness in reducing symptoms associated with rosacea-like skin lesions in experimental settings.

This article reviews the complex roles and therapeutic potential of Mesenchymal Stem Cells across various medical applications, emphasizing their anti-inflammatory and tissue repair functions rather than cell replacement or differentiation, and concludes that more precise measurement of their survival and effectiveness is needed.

Dermoscopy helped diagnose discoid lupus erythematosus in two patients without needing skin biopsies.

This study found that elastic fibre arrangements in the skin of domesticated mammals vary with hair density, with densely-haired species having horizontal fibres and sparsely-haired ones exhibiting a sponge-like system.

This study suggests that dermoscopy can help identify and distinguish various rosacea subtypes, improving clinical diagnosis and treatment decisions.

This study observed that human growth hormone treatment in osteoporosis patients appeared to improve skin thickness and restore dermal structures towards normal without stimulating hair, sebum, or melanin.

In this study, implantable vascularized engineered thrombi using autologous whole blood improved skin wound healing in rats by promoting robust microcapillary networks and accelerating healing processes.

This study found that mesenchymal stem cells sourced from hair follicle outer root sheath showed higher differentiation efficiency and angiogenic potential for vascular graft applications compared to adipose-derived stem cells.

This review assessed experimental studies on herbs used for alopecia, identifying potential mechanisms involving hair cycle management and keratinocyte processes, but highlighted a need for improved evidence on quality control and toxicity of these herbal treatments.

In this study, the researchers found that transplanted hair follicles undergo significant morphological changes, including a thickened dermal sheath and increased hair shaft diameter, which are associated with altered follicular vascularization.

This study found that canine adipose-derived mesenchymal stem cell-derived dermal papilla-like tissues promoted new hair follicle formation and increased vascularization in mice, suggesting potential for hair regeneration.

This study observed that both Factor XIIIa+ dermal dendrocytes and microvasculature size decreased with scalp aging and that alopecia changes resembled stress-induced premature senescence.

This study found that a single dose of 1 mg/kg dexamethasone promoted wound healing in septic mice but delayed it in normal mice.

This study demonstrated that human skin can be efficiently reinnervated using human induced pluripotent stem cell-derived neural stem cells, promoting skin vitality and sensory reinnervation comparable to physiological conditions.

This study found that AiQingHua oil improved microcirculation and promoted hair regeneration in mice with testosterone-induced alopecia.

In this study, researchers found that dermoscopy does not provide distinguishing features for diagnosing scalp contact dermatitis from topical minoxidil compared to other causes of severe scalp itching.

This study found that transplanting hair follicles into human scars may remodel fibrotic tissue and reduce scarring by altering collagen structure and decreasing pro-fibrotic factors.
