January 2024 in “International journal of molecular sciences” This review article addresses how the TRPV4 ion channel helps cells respond to mechanical and environmental stimuli, discussing its role in calcium signaling crucial for tissue repair and fibrosis across various organ systems, and highlighting potential therapeutic targets from animal and disease models.
May 2025 in “Science Advances” In this study, researchers reported that hair follicle stem cells maintain quiescence through a PIEZO1-dependent mechanism that senses mechanical forces and translates them into localized calcium influx, involving a transcriptional network that regulates cell adhesion and cytoskeleton-related genes.
This study found that encapsulating dermal papilla spheroids in alginate hydrogel with extracellular matrix proteins increased alkaline phosphatase activity, suggesting an enhanced manipulation of dermal papilla activity.
