The hair follicle is an organ found in mammalian skin. [1] It resides in the dermal layer of the skin and is made up of 20 different cell types, each with distinct functions. The hair follicle regulates hair growth via a complex interaction between hormones, neuropeptides, and immune cells. [1]
Hair follicles are micro organs-formed by the interaction between epidermis and dermis (Ji et al., 2021). Thus, these structures are composed of cells that arise from two different embryonic tissue sources, ectoderm and mesoderm (Ji et al., 2021).
17 lut 2021 · The hair follicle (HF) is a highly conserved sensory organ associated with the immune response against pathogens, thermoregulation, sebum production, angiogenesis, neurogenesis and wound...
30 paź 2023 · Hair follicles harbour exceptional regenerative abilities as they contain multiple somatic stem cell populations such as hair follicle stem cells (HFSCs) and melanocyte stem cells.
22 lut 2024 · Herein, we review the functional anatomy of hair follicles and the cell signaling events that play a role in follicle cycling. We also discuss the pathology of androgenetic alopecia and the known molecular mechanisms underlying this condition.
9 cze 2021 · Hair follicles develop from flat, disc-like structures called placodes in the epidermis — the surface layer of skin cells above the dermis. Morita et al. 2 used time-lapse live imaging and...
1 sty 2022 · During the hair cycle, a complex remodeling and regeneration of the non-permanent portion of the hair follicle takes place together with dramatic changes in the mesenchyme, the extracellular matrix, the vasculature and innervation, and the hair-follicle-associated cell populations.
