Abstract
The present invention relates to a composition including plant-derived recombinant human serum albumin, lipids, and plant protein hydrolysates as active ingredients for cryopreservation of stem cells or primary cells, and use thereof, more particularly, to a composition including plant-derived recombinant human serum albumin, lipids, and plant protein hydrolysates as active ingredients for cryopreservation of stem cells or primary cells, in which the albumin, lipids, and plant protein hydrolysates are present in sufficient quantities to reduce cell death caused by freezing while maintaining animal-free and xeno-free conditions during long-term preservation of stem cells or primary cells; and to a method for cryopreservation of stem cells or primary cells using the composition.
