This study found that CXCL12 inhibits hair growth via the CXCR4/STAT signaling pathway, suggesting that targeting this pathway could be a promising approach for promoting hair growth.

This study found that skin-infiltrating neutrophils play a crucial role in triggering chronic itch in atopic dermatitis by promoting skin hyperinnervation and enhanced expression of itch signaling molecules in a mouse model.

This study concluded that the CXCL12–CXCR4 signaling pathway significantly contributes to hair loss in androgenetic alopecia and alopecia areata by promoting inflammation and fibrosis, whereas inhibiting this pathway can restore hair growth and follicle health.

In mouse models, this study showed that transplanted dermal papilla and dermal sheath cells can integrate into hair follicles, promoting hair growth and extended anagen phases, with their effectiveness influenced by factors such as immune response and cell passage number.
