Cultures of keratinocyte cells are provided which are free from nonautologous fibroblasts and organ extracts, and which have a high speed of cell amplification for a minimum seeding density. The cultures can be cryopreserved in a buffered isotonic medium containing serum and a cryoprotectant. The cultures are produced by a process that does not involve the use of a feeder layer and organ extracts. A culture medium which can be used contains Medium 199, serum, epidermal growth factor, cholera toxin and/or hydrocortisone, and optionally insulin. A substance for wound healing and for cosmetic applications is derived from cultured human keratinocytes. A non-viable total keratinocyte lysate for use in promoting wound healing is produced by growing keratinocyte cells on a support, detaching the cells from the support, and lysing the detached cells to obtain the lysate which may be frozen and lyophilized. The cells may be grown without using a support to produce the lysate, or to produce a non-viable keratinocyte cell culture lyophilisate or spray dried non-viable keratinocyte cell composition for use in healing wounds.

The invention relates to a pigment-containing artificial skin detection model and a preparation method thereof.
