Carrier for cell delivery.

Problem to be solved. To provide a carrier for cell delivery that can deliver an active ingredient to a cell and a living tissue with high reliability and has all of antioxidant activity, intracellular absorptivity, intracellular disintegration properties, stability and safety. Solution. Provided is a carrier for cell delivery, the carrier comprising: a vitamin derivative capable of simultaneously activating an autophagy-related gene and a synthetic gene for cathepsin; a stimulus-responsive polymer-containing molecule; an emulsion stabilizer; an active ingredient; and a lipid. Since the active ingredient is enclosed in the carrier for cell delivery, the carrier can deliver the active ingredient to a cell and a living tissue with high reliability.
