Studysummary This study found that Merkel cells in dogs are most numerous in sensory receptive areas like oral mucosa and facial skin, indicating a potential role in tactile sensation. Our plain-language summary of this paper — not a Tressless recommendation.
The study mapped and quantified Merkel cells (MCs) in the skin and mucosae of 21 adult dogs, analyzing 1,187 samples. It found that MCs were unevenly distributed, with higher densities in sensory receptive areas like the lips and snout, and lower densities in areas like the anal and genital mucosa. The distribution and density of MCs in dogs were similar to those in other mammals, suggesting comparable functions. The number of MCs did not significantly vary with age, sex, breed, coat, or pigmentation. The study provided foundational data for future research on MC functions in both normal and damaged canine tissues.
