‘Frog Skin’ Cell Type Found in Mammal Mouths
Looking deep within mammalian spit-producing glands, scientists were recently surprised to find an ancient cell type long thought to exist primarily in the slimy skin of frogs and fish. Such discoveries are rare in modern science—and researchers say these tiny cells could fill many more roles than previously thought.
The scientists were trying to determine which cell produces a certain protein involved in salivary gland growth and repair. Using a technique called single-cell RNA sequencing, they isolated candidate cells…
