The present invention relates to a plant stem cell derived from the cambium of family Solanaceae, and to a method for isolating and culturing the same. A stem cell derived from the cambium of family Solanaceae, according to the present invention, is useful as it can be isolated in an undifferentiated state without undergoing a dedifferentiation process and stably maintained without causing any variation in the cell growth rate and growth pattern even during long-term culture, thereby enabling large-scale culture. Moreover, the stem cell derived from the cambium of family Solanaceae and the culture thereof, according to the present invention, are useful for preventing and delaying aging as they have the effects of inducing biosynthesis of procollagen and more efficiently inhibiting the generation of enzymes related to aging than retinoic acid, which is known as having an excellent effect in skin wrinkle improvement.
