Squamous differentiation. K-HME cells were grown in the center of a Matrigel® sandwich. A. Phase contrast; and B. Hematoxylin and eosin stained section after 10 days. Bright-pink center is keratin (*), the triangle indicates an area equivalent to the stratum corneum, the arrows identify cells equivalent to the stratum basale of a stratified epithelium. C. Phase contrast of similar culture after 1 day 20×
