Annotation rationales
Papillary dermal fibroblasts occupy the superficial dermis beneath the epidermis and have a matrix and morphogen profile adapted to the epidermal interface.
Functional implications
They maintain the dermal–epidermal junction, support epidermal renewal and contribute to superficial wound repair and skin architecture.
