This case report details a rare instance of malignant proliferating trichilemmal tumour in a 60-year-old male, emphasizing the significance of histochemical and immunohistochemical markers for accurate diagnosis and differentiation from squamous cell carcinoma.

This study found that partially bald scalps of Indian men with androgenic alopecia retain progenitor cells marked by CD34 and Sox9, but these cells are absent in completely bald areas, suggesting that interventions might be more effective if focused on early-stage hair loss.

In this study, researchers found that minoxidil nanocrystals delivered using MG-MXD@NP, containing methylcellulose and gum arabic, significantly improved hair growth in mice compared to a standard minoxidil lotion, with enhanced delivery to skin tissues and increased markers of hair follicle stem cell activity.

This study found that CGF may be effective in reducing inflammation and improving skin conditions in psoriasis, particularly in patients resistant to other treatments.

This study found that combining platelet-rich plasma therapy with minoxidil significantly improved hair growth and hair follicle cell proliferation in men with androgenetic alopecia compared to either treatment alone.

CD8+ T cells attack hair follicle stem cells, causing scarring and hair loss in Discoid Lupus.

This study explored the diversity of melanocyte stem cell subpopulations in the hair follicles of adult female mice and identified novel groups with distinct immune privilege regulation, suggesting a heterogeneous landscape that future research should consider.

This study found that in atrophic acne scars, inflammation infiltrates the pilosebaceous unit over time, affecting resident stem cells and hindering the normal regeneration of the epidermis and adnexal structures, leading to scarring.

This study observed that while some progenitor cells were present in the partially bald areas of androgenic alopecia in Indian men, the completely bald areas lacked these cells, suggesting potential timing for therapeutic intervention targeting hair follicle stem cell activity.

This study found that exosomes from human dermal papilla cell cultures, particularly in an oxygen-permeable 3D environment, most effectively supported hair follicle stem cell maintenance and promoted hair follicle formation in vitro.

This study found that zebrafish and stickleback fish use similar genetic programs for tooth regeneration, despite differences in their dental structures.

This study found that isolated hair follicle outer root sheaths from mice can regenerate new dermal papillary structures in vitro, with stem cells and neutrophils playing key roles in the regeneration process.

LED light helps human hair root cells grow and move by activating certain cell pathways.

LED light helps human hair root cells grow and prevents them from dying by activating specific growth pathways.

This review discusses the role of stem cells in the hair follicle bulge region for regenerative medicine and reports no new clinical results; the authors highlight the complexities in studying these cells' involvement in alopecia.

This study observed that using transfected human cord blood cells enhanced skin wound healing in rats by promoting angiogenesis and earlier termination of proliferation compared to untransfected cells.

AA-PRP injections significantly promote hair growth but need better study design for clear efficacy.

This study confirmed the presence of specific stem cell populations in SKH1 hairless mice skin, including CD34+/α6-integrin+ cells, which are important for investigating ultraviolet radiation-induced carcinogenesis.

This study found that Stat3 influences the differentiation and migration of keratinocytes, potentially impacting epithelial carcinogenesis, by examining Stat3 activation or deletion effects in mouse models.

This study found that Stat3 deletion in certain skin cells led to increased differentiation and altered stem cell behavior, suggesting its significant role in skin tumor development and keratinocyte migration.

This study found that hair follicle stem cells from young rats can be induced in vitro to differentiate into corneal epithelium-like cells using homogenate of rabbit corneal limbal stroma.

This review discusses recent advances in using stem cells for skin repair and regeneration after severe burn injuries, but it reports no new clinical results.

In this study, the Foxn1(-/-) nude phenotype was associated with an altered regulation of epithelial progeny in skin, offering a valuable model for investigating stem cell niche maintenance and regulation.

This study found that intradermal injections of plant-derived exosomes in adults with early-stage alopecia increased stem cell activity, activated Wnt signaling pathways, and reduced certain immune cell populations, providing insights into their role in hair follicle regeneration and suggesting potential for hair restoration therapy.

This report describes a case where a woman's hair loss following COVID-19 vaccination improved after treatment with autologous CD34+ hematopoietic progenitor cells and umbilical cord blood-derived mesenchymal stem cells, with no significant adverse effects observed over the 12-week treatment period.

In this study, porcine collagen acellular dermal matrix scaffolds combined with mice platelet-rich plasma were associated with increased hair density and follicle regeneration in mice with alopecia, suggesting a potential therapeutic approach.

In this research, scientists developed a compression therapy model using immobilized mice, successfully analyzing skin without causing injury, and observed increased epidermal thickness and changes in adipocyte volume, with no increase in DNA damage markers.

This study explored how T cells interact with hair follicles in primary cicatricial alopecias by using spatial transcriptomics across mice, dogs, and human samples, revealing specific communication pathways and potential drug targets like CFD and S100A8/9 for future therapeutic research.

Stimulating OR10J1 can promote hair growth and may help treat hair loss.

This study found that both marine and bovine collagen peptides may help prevent hair loss by supporting epithelial hair follicle stem cell functions, with marine peptides maintaining hair in the growth phase and bovine peptides increasing stem cell presence in hair follicle regions.
