  • Patent number: 10669527
    Abstract: An artificial skin culture container according to the present invention can solve the problems of the contraction of the dermal layer of artificial skin and the detachment thereof from the culture container, which result from an interaction between collagen and fibroblasts existing in the dermal layer of artificial skin during the production of the artificial skin, by using agar and hydrophobically modifying a portion of the agar. Therefore, the use of the culture container enables to stably culture artificial skin and produce artificial skin similar to the human skin. In addition, the artificial skin culture container of the present invention comprises agar, and thus a culture solution can be supplied through a side portion as well as a lower portion of the culture container, which allows to effectively culture artificial skin.
