Fibroblasts are diverse mesenchymal cells that participate in tissue homeostasis and
disease by producing complex extracellular matrix and creating signaling niches through …

Hair follicles are essential appendages of the mammalian skin, as hair performs vital
functions of protection, thermoregulation and sensation. Hair follicles harbour exceptional …

Adult mammalian skin wounds heal by forming fibrotic scars. We report that full-thickness
injuries of reindeer antler skin (velvet) regenerate, whereas back skin forms fibrotic scar …

Multipotent stromal cells (MSCs) are vital for development, maintenance, function, and
regeneration of most tissues. They can differentiate along multiple connective lineages, but …

Dermal fibroblasts exhibit considerable heterogeneity during homeostasis and in response
to injury. Defining lineage origins of reparative fibroblasts and regulatory programs that drive …

The skin forms a crucial, dynamic barrier between an animal and the external world. In
mammals, three stem cell populations possess robust regenerative potential to maintain and …

The process wherein dividing cells exhaust proliferative capacity and enter into replicative
senescence has become a prominent model for cellular aging in vitro. Despite decades of …

Specialized connective tissues, including bone and adipose tissues, control various
physiological activities, including mineral and energy homeostasis. However, the identity of …

Despite the growing interest by researchers into cellular senescence, a hallmark of cellular
aging, its role in human skin remains equivocal. The skin is the largest and most accessible …

Hair follicle stem cells are regulated by dermal papilla fibroblasts, their principal signaling
niche. Overactivation of Hedgehog signaling in the niche dramatically accelerates hair …
