This study found that DKK1 and WNT10b are paracrine factors that modulate hair follicle stem cell differentiation inhibition, contributing to androgenetic alopecia by affecting Wnt signaling in androgen-sensitive dermal papilla cells after dihydrotestosterone stimulation.

This review discusses lung regeneration and highlights the role of facultative stem/progenitor cells, but it reports no new findings and calls for further exploration of underlying mechanisms.

This review revisits the mechanisms of wound induced hair follicle neogenesis in mice and concludes that the process involves canonical WNT signaling activated by Fgf9 from γδ T cells, but more research is needed to fully understand its cellular bases.

In this study, patients receiving adipose-derived stromal vascular cell transplantation for alopecia areata experienced significant hair regeneration, increased growth, and improved hair quality after 3 and 6 months, indicating potential efficacy of this stem cell-based therapy for hair loss.

This study found that lymphatic vessels in mice are important for hair follicle development and organization, as their depletion blocks hair growth.

This study identified hair shaft progenitors in the matrix that regulate hair growth and pigmentation by creating a niche dependent on stem cell factor, implicating KROX20+ cells in these processes.

This review discusses recent advancements in the management and diagnosis of primary cicatricial alopecias but reports no new clinical results; emerging insights suggest sebaceous gland dysfunction may play a role in their etiopathogenesis.

This review discusses advances and challenges in skin tissue engineering, focusing on developing 3D constructs for functional skin substitutes, and reports no new clinical results.

This study found that micrografts containing human hair follicle mesenchymal stem cells significantly increased hair count and density compared to placebo over 58 weeks in patients experiencing hair loss.

The researchers reported that in mice, prolactin signaling in the skin epithelium inhibits hair follicle stem cell activation, promoting quiescence during periods of high serum prolactin like pregnancy and lactation.

This study observed that autologous bone marrow derived mononuclear cells and follicular stem cells were both safe and effective for improving resistant alopecia areata and androgenetic alopecia, with no serious adverse events.

This report reviews current advances in hair follicle regeneration for tissue-engineered skin grafts and highlights the feasibility and challenges of creating human hair follicles in this setting, suggesting key bioengineering requirements.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

This study found that Ldh activity in hair follicle stem cell-mediated squamous cell carcinoma is not necessary for tumorigenesis, as its modulation did not affect the cancer's development or characteristics.

This study found that transforming growth factor-β1 and CX3CR1 are crucial for recruiting specific macrophages essential for wound-induced hair growth in mice.

This study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.
