September 2023 in “Medicine” This study found increased infiltration of specific immune cells, such as γδ T cells and CD8+ T cells, in the bald scalp of male androgenetic alopecia patients, and identified four key immune-related genes potentially involved in hair loss development through interferon-γ signaling pathways.
January 2026 in “Materials Horizons” This source highlights the challenge in achieving scarless healing with skin appendage regeneration for wounds and notes that vitamin A derivatives show promise for promoting new follicle growth. However, specific results from this research are not reported in the abstract.

September 2025 in “Frontiers in Microbiology” This review article proposes a possible skin-gut-fibrosis axis, suggesting that gut microbial metabolites may influence the development of keloids and hypertrophic scars by affecting immune responses and fibrotic signaling pathways, although direct evidence in skin fibrosis remains limited.
January 2026 in “Preprints.org” This review explores current knowledge on fibroblast lineage specification and its impact on scar-free wound healing, noting that early fetal skin fibroblasts support regeneration, while later developmental shifts lead to fibrosis, highlighting potential strategies to reprogram adult fibroblasts for regenerative repair.
September 2024 in “JAMA Dermatology” In this case series, low-dose oral metformin was associated with improvements in symptoms and gene expression changes in Black female patients with treatment-resistant central centrifugal cicatricial alopecia, suggesting a potential therapeutic role for metformin in managing this condition.
