Abstract

Abstract: The epidermis is a stratified epithelium. Compared to that for monolayered epithelia, understanding of the cell biology of stratified epithelia lags far behind. The major reason for this is the limitation of methods to reproduce the epidermis in vitro using cultured keratinocytes: for example, cultured keratinocyte cell sheets lack Langerhans cells, melanocytes, nerves, sweat ducts, and hair follicles. One current way to overcome this limitation is to observe the epidermis in vivo via whole‐mount staining and three‐dimensional imaging. Here, we describe how to prepare epidermal sheets from skin and how to immunostain and observe them in whole mount. © 2022 Wiley Periodicals LLC.
