Microsized skin cell beads consisting of 3D layered structures with epidermal and dermal cells have been fabricated. The beads are monodisperse, type-I collagen beads encapsulating dermal cells and covered by epidermal cells. The beads can be used in individual analyses of cellular functions and respond to chemical stimulation.
