Detailed explanation-1: -Epidermal cells can be engineered to express a gene either permanently or transiently. These genes could encode growth factors or cytokines, as mentioned earlier, or they may antagonize some of the inhibitory factors found in chronic wounds.
Detailed explanation-2: -Subsidiary cells, also called accessory cells, surround and support guard cells.
Detailed explanation-3: -23.2. Guard cells are another type of plant single-cell models to study early signal transduction and stress tolerance mechanisms in plants. Guard cells are surrounded by stomatal pores and are located in leaf epidermis. Guard cells control influx and efflux of CO2 and water from leaves, respectively.
Detailed explanation-4: -Cells of epidermis are flat. Forms a continuous layer. There are no intercellular spaces. Secretes a waxy layer (cuticle) to prevent loss of water.
