This study found that adipose-derived mesenchymal stem cells produced more anti-inflammatory and pro-angiogenic cytokines on electrospun scaffolds, which enhanced wound healing and macrophage activity in a rat model.

This study found that human follicle dermal papilla cells promote survival, proliferation, and tubulogenesis of microvascular endothelial cells, highlighting their significant role in hair follicle vascular remodeling.

This study found that in vitro, beard dermal papilla cells stimulated keratinocyte proliferation via androgen-dependent growth factors, while androgenetic alopecia cells released TGF-β1, inhibiting keratinocyte growth.

This review explores the mechanisms of intratesticular control of steroidogenesis and indicates the need for further controlled studies; it presents no new experimental findings.

In laboratory settings, this study suggests that Serenoa repens and N-acetyl glucosamine with milk proteins may promote hair follicle vascularization through specific cellular interactions and actions.

This article discusses the interactions between keratinocytes and melanocytes in maintaining epidermal and hair follicle homeostasis, without reporting new experimental results.

This review discusses the unique features of dermal white adipose tissue, its interaction with hair follicles, and its role in skin physiology, reporting no new experimental findings.

This study found that the survival and proliferation of mouse melanocytes expressing the GNAQQ209L oncogene were impaired by interactions with the epidermal microenvironment, suggesting a possible mechanism for the rarity of these mutations in epidermal melanomas.

This review discusses the role of various hormones in diffuse hair loss and emphasizes the need for further research to clarify their complex interactions and potential therapeutic implications, but reports no new clinical results.

This study identified TGF-β2 as a crucial signal in hair follicle stem cell regeneration, highlighting its role in counteracting BMP signaling to promote tissue regeneration.

This study found that increased expression of type II 5α-reductase, androgen receptors, and Hic-5/ARA55 in dermal papilla cells upregulates androgen sensitivity, playing a key role in androgenetic alopecia pathogenesis.

This upcoming review will investigate the role of hair follicle fibroblasts in androgenetic alopecia, focusing on their interactions with androgens and impact on cellular signaling and fibrosis.

This review discusses how using hydrogels as a three-dimensional culture platform for mesenchymal stem cells might affect the production of extracellular vesicles, highlighting challenges in standardization and opportunities to boost EV yield via combined hydrogels and bioreactor methods.

This study found that nerve growth factor signaling in organ-cultured human hair follicles inhibits hair growth by inducing apoptosis-driven hair follicle regression.

This study found that GNAQQ209L expression in mouse melanocytes led to reduced survival in the interfollicular epidermis due to paracrine signaling, while GNAQQ209L boosted survival in a different microenvironment.

This review discusses the paracrine properties of cardiac stem cells and pericytes in regenerative medicine for ischaemic diseases and reports no new clinical results.
