What are mammalain cells means?

Mammalian cells refer to cells derived from mammals, which are warm-blooded vertebrates characterized by the presence of mammary glands, fur or hair, and three middle ear bones. These cells are often used in biological research and biotechnology due to their similarity to human cells, making them valuable for studying disease mechanisms, drug development, and genetic engineering. Common types of mammalian cell lines include fibroblasts, epithelial cells, and immune cells, which are cultured in laboratories for various scientific applications.
