In this study, researchers identified Tenascin-C as a marker for touch dome keratinocytes, which maintain themselves and can develop into Merkel cells following injury, showing they share molecular traits with various epidermal keratinocytes.

This study identified key cells and pathways needed for the development of touch receptor patterns in mouse skin, notably that certain keratinocytes are crucial for innervation patterns, while Merkel cells and BMP signaling have distinct roles.

This article discusses recent advances in understanding the mechanisms of tactile end organs in the epidermis and hair follicles from studies of mouse hairy skin, but it reports no new clinical results.

Touch domes in human skin are complex sensory structures not directly linked to hair.

The document concludes that stem cells and their environments are crucial for skin and hair health and have potential for medical treatments.
