Abstract: The object of the present invention is to provide a porous scaffold for cell culture which does not deteriorate even when subjected to sterilization treatment such as autoclaving, and is capable of culturing various cells; and a production method thereof. The present invention is a porous scaffold for cell culture comprising a crosslinked aggregate of gelatin and xanthan gum or an analog thereof, wherein the shape of the porous scaffold for cell culture is not changed during heat sterilization; and a method of producing a porous scaffold for cell culture, comprising: a mixing and foaming step of mixing and foaming gelatin and xanthan gum or an analog thereof; and a crosslinking step of crosslinking gelatin and xanthan gum or an analog thereof in the obtained foam.

Abstract: The cell state estimation system includes an appearance information acquisition portion acquiring appearance information of a second cell different from a first cell to be cultured, in which at least a part of a culture medium providing a growth environment to the first cell provides a growth environment to the second cell; a physical property measurement portion measuring at least one physical property of at least one of the culture medium that has provided a growth environment of the second cell and the second cell; and an estimation reference information portion storing estimation reference information referred to for estimating a state of at least one of the first cell and the culture medium, in which the estimation of the state of at least one is based on at least one of a result acquired by the appearance information acquisition portion and a result measured by the physical property measurement portion.

Abstract: A method of producing a culture solution for human or animal cell culture includes bringing an iron supply source including an iron-containing section and a plating layer provided thereon into contact with an aqueous medium to supply iron from the iron supply source to the aqueous medium.

Abstract: In order to induce aging while cutting the costs associated with adding cytokines at different aging stages, in a system for aging induction including a first culture chamber for perfusing, with a culture medium, a subject of aging-induction, the subject of aging-induction being derived from a living organism; a second culture chamber for perfusing, with a culture medium, a secretor that secretes a cytokine; and a control device for aging induction including a detection unit, a memory unit and a control unit, a protocol for aging induction defining a procedure of aging induction is stored, and in the control unit, an aging state of the subject of aging-induction is detected with a detection unit, and based on the protocol for aging induction, a flow rate at which the culture medium containing the cytokine secreted by the secretor is supplied to the subject of aging-induction is controlled according to the aging state of the subject of aging-induction.
