Nails are hard plates of dead epidermal cells that have been converted into keratin, a tough, fibrous protein. This transformation occurs in the nail matrix, where new cells are produced and push older cells outward, leading to the formation of the nail. The keratin provides strength and resilience, allowing nails to protect the fingertips and enhance tactile sensitivity.
Hair and nails are derived from the epidermal layer of the skin. Cells known as keratinocytes in the epidermis produce a protein called keratin, which is the main structural component of both hair and nails.
The tough protective protein found in epidermal cells is called keratin. Keratin helps to provide strength and structure to the skin, hair, and nails.
Melanocytes, which produce melanin for skin pigmentation, are found in human epidermal cells but not in leaf epidermal cells. Additionally, human epidermal cells contain structures like Langerhans cells for immune response, which are not present in leaf epidermal cells.
No, epidermal cells from petunia do not stain with phloroglucinol. Phloroglucinol is typically used to stain lignin in plant tissues, not epidermal cells. The stain mainly reacts with lignin, which is absent in the epidermal cells.

Nails are made up of layers/plates of keratinized epithelial cells.
Epidermal cells undergo a process called keratinization to produce nails. During keratinization, the epidermal cells in the nail matrix produce keratin, a tough protein that forms the structure of the nail plate. As these cells mature and move upwards, they become tightly packed and eventually form the hardened nail plate that we see.

Merkel cells compose about 8% of the epidermal cells. These specialized cells are found in the deepest part of the epidermis and are involved in the sensation of touch.
HIV mainly attacks cells in the immune system. I'm not aware of a major impact on skin (epidermal) cells.
