The invention relates to preparation and a purification production process of mesenchymal stem cells (MSCs) derived exosomes, and application of the exosomes as a non-cell therapy in the treatment of acute lung injury. The MSCs deriving the exosomes belong to the wall adhesion type of stem cells, and the preparation and purification process have the characteristics that (1) parathyroid hormone is added specially for the preparation of MSCs condition medium, and (2) discontinuous Ficoll density gradient method and immunomagnetic beads separation and purification method are combined for separation and purification so as to obtain the exosomes. Rat acute lung injury (ALI) model experiments confirm that the exosomes can be used for treatment of ALI, so as to lay the foundation for the realization of non-stem cell therapies to substitute stem cells therapies.
