Stem cells residing in the epidermis and skin appendages are imperative for skin homeostasis and regeneration.These stem cells also participate in the repair of the epidermis after injuries,inducing restoration of tissue integrity and function of damaged tissue.Unlike epidermis-derived stem cells,comprehensive knowledge about skin appendage-derived stem cells remains limited.In this review,we summarize the current knowledge of skin appendage-derived stem cells,including their fundamental characteristics,their preferentially expressed biomarkers,and their potential contribution involved in wound repair.Finally,we will also discuss current strategies,future applications,and limitations of these stem cells,attempting to provide some perspectives on optimizing the available therapy in cutaneous repair and regeneration.
Stem cells are the core of tissue repair and regeneration,and a promising cell source for novel therapies.In recent years,research into stem cell therapies has been particularly exciting in China.The remarkable advancements in basic stem cell research and clinically effective trials have led to fresh insights into regenerative medicine,such as treatments for sweat gland injury after burns,diabetes,and liver injury.High hopes have inspired numerous experimental and clinical trials.At the same time,government investment and policy support of research continues to increase markedly.However,numerous challenges must be overcome before novel stem cell therapies can achieve meaningful clinical outcomes.
