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 review discusses advancements in plant cell culture technology for producing potent natural cosmetic ingredients and reports no new experimental results.

This study suggests that skin-derived precursors from Sox2(+) hair follicle dermal cells have the potential to function as dermal stem cells, supporting hair morphogenesis, dermal maintenance, and wound-healing.

Hair graying is caused by the loss of pigment cells due to poor maintenance of stem cells in the hair follicle.

This study found that the transcription factor Gata6 regulates the sebaceous duct lineage identity and plays a crucial role in epidermal wound healing by enabling dedifferentiation and broader lineage capabilities in post-mitotic cells.

This study reports that the side population technique can isolate melanocyte stem cells from human hair follicles, potentially allowing them to be used for skin pigmentation repopulation.

This study found that in identifying bulge stem cells, CD34 is more specific in mice and CD200 in humans, with CD200 potentially marking progenitor and partially differentiated cells.

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.

This study found that post-hematopoietic cell transplantation epidermal grafting significantly reduced chronic wound size in patients with recessive dystrophic epidermolysis bullosa.

This study suggests that pilomatricoma can differentiate towards various hair follicle structures, including hair matrix, hair cortex, follicular infundibulum, outer root sheath, and hair bulge.

This review examines the differentiation potential of epithelial cells from various sources in hair follicle formation, concluding that complex interactions are required for hair-specific characteristics, which were achieved in vivo but not in vitro.

This narrative piece considers how epigenetic factors may influence the processes of skin wound healing, including hair follicle formation, but it presents no new experimental results.

This study utilized a pigmented human epidermal equivalent model to incorporate melanocytes into the epidermis and found enhanced differentiation potential compared to conventional in vitro systems, reflecting in vivo cellular trajectories and highlighting melanocyte-to-keratinocyte communication pathways.

This study reported that stress can induce hair graying in mice through noradrenaline-mediated depletion of melanocyte stem cells in hair follicles, providing a mechanism that connects stress to hair color changes.

This study found that "early" transit amplifying cells, marked by CD271, are the first keratinocyte stem cell progenitors with distinct features, playing a significant role in early epidermal differentiation and regeneration.

This study found that differentiated airway epithelial cells can revert into functional stem cells in vivo, suggesting a more general role for this dedifferentiation process in tissue regeneration in higher vertebrates.

This study found that melanoma cells develop resistance to therapies through dedifferentiation but become vulnerable to ferroptotic cell death, suggesting a potential therapeutic approach to target resistant forms of melanoma.

This study observed that NSPC predominantly differentiated into neurons when exposed to serum fractions with molecules under 100 kDa, particularly with biomaterial and fibronectin, in the presence of basic fibroblast growth factor.

In this study, researchers developed a method to differentiate human iPSCs into cells that can generate all lineages of hair follicles, potentially aiding treatments for hair loss and skin disorders.

This study found that human induced pluripotent stem cells differentiated precisely to express certain markers during a specific window could enable successful hair follicle generation when transplanted.

This study demonstrated that hair follicle cells can be induced to differentiate into cardiomyocyte-like cells in vitro, exhibiting characteristics and spontaneous beating typical of cardiac muscle, without genetic modification.
