The invention is directed to methods for treating inhalation injuries. Such methods utilize novel cell compositions such extraembryonic cytokine secreting (ECS) cells and Amnion-derived Multipotent Progenitor (AMP) cells and novel cellular factor-containing solution compositions such as extraembryonic cell-derived cellular cytokine solution, Amnion-derived Cellular Cytokine Solution (ACCS), and physiologic cytokine solution (PCS) compositions. The compositions may be used alone or in combination with each other and/or other agents.
