Abstract
The present invention provides a novel material for activating epidermal cell multiplication on which not only effective adhesion and multiplication of human and mammalian epidermal cells is accomplished also intercellular adhesion is promoted to form a plain cellular layer. The present invention provides a material for activating epidermal cell multiplication which contains silk fibroin of .alpha.-type or .alpha.-helix X-ray diffraction pattern as a principal constituent. The present material fulfills the principal requirements for activating epidermal cells of greatly improved cellular adhesion rate, multiplication, intercellular adhesion and growth of cell layers.
