Hair follicle stem cells rely on nearby blood vessels for their maintenance and function.

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 review explores the mechanism and potential applications of wound-induced hair follicle neogenesis but reports no new clinical results, highlighting the need for further research in hair regeneration therapies.

This study suggests that using sebaceous glands from rat tail skin samples may effectively capture hair follicle stem cells, potentially aiding skin regenerative medicine when available tissue is limited.

This study found that cells from the upper hair follicle exhibited more active growth compared to other segments in vitro, suggesting their potential as a source of hair follicle stem cells.

In this study, researchers found that hair follicle stem cells in mice can generate both hair follicle and epidermis cells, highlighting their potential bipotency.

In this study, upper-bulge epidermal stem cells in mouse hair follicles were shown to play a role in forming tactile sensory units by creating an extracellular matrix that supports nerve interactions.

This study reported that 5% minoxidil nanoparticles enhanced hair growth more effectively in mice than a commercial minoxidil solution, with significantly higher drug accumulation in the upper hair follicles.

This study claims that the upper dermal sheath of rat vibrissa follicles can induce hair growth under specific conditions, challenging prior beliefs about its lack of inductive capacity.

This study found that upper-bulge epidermal stem cells in mouse hair follicles are specialized for nerve interactions, crucial for forming tactile sensory units, and influence touch responses via EGFL6 and αv integrin pathways.

This study found that hair-follicle-associated-pluripotent (HAP) stem cells can be cryopreserved for future use in nerve and spinal cord repair, with human trials being planned.

Basal cell carcinoma mostly starts from cells in the upper skin layers, not hair follicle stem cells.

This study found that hair follicle matrix progenitors differentiate into various layers asynchronously, with early progenitors forming the companion layer and later progenitors generating the inner root sheath and hair shaft.

This study observed two cases of pigmented epithelioid melanocytoma suggesting potential differing origins: one from a hair follicle's outer root sheath and another from an intradermal nevus.

Hair follicle stem cells can become heart muscle cells.

This study observed that isoproterenol directs hair-follicle-associated pluripotent stem cells to differentiate into cardiac muscle cells in large numbers, forming tissue sheets of beating heart muscle cells in culture.

This review discusses the genetic and molecular factors involved in human hair follicle development and cycling, highlighting identified genes and pathways associated with hair diseases but reports no new results.

This study found that Shh from neurons signals to Gli1-expressing cells in the hair follicle, cultivating a niche where these bulge cells can potentially transform into epidermal stem cells in wound healing.

This study found that hemoglobin α is upregulated in epidermal keratinocytes after UV exposure and may function as an antioxidant, particularly for hair follicle stem cells.

In this study, topical application of ginsenosides Rb₁ and Rd in mice increased cell proliferation in hair follicles, suggesting they may help prevent hair loss by promoting growth through p63 induction.

This study reports that patients with specific MFN2 mutations, including p.Arg707Trp, exhibit significant upper body fat overgrowth with suppressed leptin production, suggesting tissue-selective mitochondrial dysfunction and potential therapeutic targets.

This study found that epidermal-specific deletion of integrin α3β1 significantly reduces papilloma formation in a skin carcinogenesis model by modulating HB stem cell behavior and CCN2 expression.

This article reviews the role of adult stem cells in tissue homeostasis and wound repair, focusing on their regulation within the murine hair follicle's specialized niche, but it presents no new findings.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This study reports that Lef1 plays a crucial role in promoting bulge stem cell differentiation towards hair fate by activating β-catenin and downstream signaling pathways during hair follicle development.

This study found that in vitro, cultured bulge cells from human hair follicles possess properties of primitive cells, supporting the hypothesis that hair follicle stem cells reside in the bulge area.

Early stage bald spots are linked to skin inflammation and damage to the upper part of the hair follicle.

This study suggests that damaged anagen hair follicles have the capability to repair themselves and resume growth by mobilizing extra-bulge epithelial cells, particularly after injuries like chemotherapy and radiotherapy.

TR3 is mainly found in hair follicle stem cells and may be involved in hair loss.

This study describes the process of isolating and analyzing multipotent stem cells from mouse hair follicles for potential use in tissue engineering and regenerative medicine.
