This article reviews advancements in understanding skin regeneration and suggests that bioengineering skin surrogates may soon enhance treatments for skin trauma, but it presents no new clinical findings.

Apoptosis in hair follicles varies by growth phase, with TGF-β possibly starting the catagen phase.

This review discusses the genetic factors involved in hair follicle morphogenesis and cycling and reports no new clinical results; it emphasizes the role of genes in hereditary hair diseases.

This review examines how hormonal, vascular, and neuropeptide factors may regulate hair growth, suggesting a combined approach could contribute to developing new treatments for hair loss; it reports no new clinical results.

This study generated a transcriptomic map of human hair follicles, identifying compartment-specific gene expression profiles that can aid in developing targeted therapies for hair follicle disorders.

This study reported that specific inhibition of the classical complement pathway with BIVV009 prevented C3 deposition along the dermal-epidermal junction in bullous pemphigoid, reflecting its potential efficacy.

This study suggests that human skin contains distinct fibroblast subsets with unique expression profiles and functions, which can be isolated to investigate their role in skin pathogenesis.

Scientists used a special imaging technique to observe that hair follicle regeneration involves cell division and structural changes, mostly in the lower part of the follicle, and that the dermal papilla at the base is crucial for regrowth.

In this study, trichocytes were shown to have potential for alternative differentiation, with mesenchymal cell influences playing a critical role in determining this process.

Mesenchymal stem cells from bone marrow and umbilical cord can help regenerate hair follicles.

This study examines various growth factors' roles in hair cell function and suggests insulin-like growth factor may stimulate hair growth, while the precise mechanism of growth inhibition remains unclear.

This study found that human embryonic and induced pluripotent stem cells differentiated into specific bulge stem cells and successfully formed new hair follicles when transplanted with mouse dermal cells in immunodeficient mice.

This study found that while extracellular matrix components like hyaluronic acid promoted larger organoid formation, other matrix components hindered hair follicle germ assembly in an in vitro model.

This study identified the dermal sheath as a key component of the hair follicle niche, essential for outer root sheath regression during the hair cycle, highlighting its importance in hair follicle support and regulation.

This study found that human hair follicle dermal cells, specifically dermal sheath cells, can serve as an alternative and potentially superior cell source for constructing the dermal component of bioengineered skin in both in vitro and in vivo settings.

This study found that Plumbago zeylanica extract and its component plumbagin may help prevent androgenetic alopecia by promoting dermal papilla cell growth and reducing SRD5A2 expression.

This study found that 18-β-Glycyrrhetinic acid, a licorice component, stimulated human hair follicle cell proliferation, inhibited testosterone 5α-reductase, and suppressed TGF-β1, suggesting potential for treating androgenetic alopecia by promoting hair growth and prolonging the anagen phase.

This study found that the Polycomb Repressive Complex 2, particularly its component Ezh2, is crucial in regulating dermal fibroblast differentiation and epidermal keratinocyte proliferation during murine skin development.

In this study, researchers found that crude extracts from Avicennia marina and its component avicequinone C inhibit mechanisms contributing to androgenic alopecia in vitro, including 5α-reductase activity and DHT-AR interactions, potentially promoting hair growth and delaying the catagen phase in human dermal papilla cells.
