TLDR The silver marmoset's skin is thin, lacks pigment cells, and has unique features like keratinized spines and specialized glands.
The study of the silver marmoset's skin revealed several unique features, including a thin epidermis and dermis with few melanotic melanocytes, and specialized structures such as keratinized spines on the corpus penis and cholinesterase-reactive nerve end-organs on volar surfaces. The skin's rubicund color was attributed to a highly vascular dermis and subcutaneous fat. Hair growth occurred in sets of 3 to 5 follicles, with alkaline phosphatase-positive cells present in hair regions. Large sebaceous glands contributed to the scrotal skin's opaque-white color, while apocrine and eccrine sweat glands were distributed variably across different body regions.
