This study found that Th17 lymphocytes may play a more crucial role than cytotoxic T cells in the development of alopecia areata due to their infiltration around the hair bulb/bulge, which exacerbates hair loss as histopathological grade worsens.

This review discusses strategies to regenerate human hair follicles using stem cells and reports no new experimental results; the authors note existing challenges and the potential of hiPSCs for future applications.

This study concluded that the new subfractionation culturing method generates highly homogeneous adipose-derived stem cells with enhanced mitogenic, paracrine, and hair growth-promoting effects compared to traditional isolation methods.

In a porcine model, this study observed that using an External Tissue Expansion Device increased epidermis thickness, cell proliferation, and vessel density at fat graft recipient sites.

This study observed that injecting a combination of human cultured dermal papilla and epithelial cells induced hair growth in a mouse model.

This study reports that sorafenib-associated facial acneiform eruption, mimicking chloracne, is a rare cutaneous adverse event which improved upon reducing or discontinuing the drug.

This study demonstrates that human hair follicle stem cells can be cultured and expanded without major changes to their phenotypes, which suggests potential for use in regenerative medicine.

This study found that serum MIF levels were significantly higher in patients with extensive alopecia areata compared to those with mild alopecia areata and healthy individuals.

In this study, CD34-positive progenitor cells in irradiated salivary glands were observed to potentially aid in blood vessel formation and remodeling, suggesting their role in tissue healing after radiotherapy.

This study reviewed the prospects and challenges of using stem cells from adipose tissue in regenerative medicine for facial rejuvenation, emphasizing the need for further research to ensure patient safety before these methods can become routine in cosmetic and reconstructive surgery.

This review evaluates existing preclinical and clinical studies on stromal vascular fraction for treating male sexual dysfunction, finding limited data and emphasizing the need for more research before conducting clinical trials.

This review examines the challenges of hair follicle regeneration and outlines strategies for bioengineering human hair follicle models, without presenting new experimental results.

This study found that TGF-β1 expression in follicular tumors correlates with differentiation degree and suggests its potential role alongside p63 in differentiating between sebaceous and follicular tumors.

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.

In this study, the researchers developed a new protocol using human-induced pluripotent stem cells to efficiently create skin hair follicle organoids, which may aid in optimizing hair follicle growth and exploring treatments for alopecia.

This study describes a protocol for generating hair follicle germ-like organoids from human skin cells, which may aid in alopecia drug discovery and understanding hair follicle regeneration.
