Abstract: Disclosed are compositions of matter, therapeutics, and protocols useful for reduction and/or reversion of pulmonary fibrosis. In one specific embodiment lithium chloride is administered together with a regenerative cell in a patient suffering from, or at risk of pulmonary fibrosis. In one embodiment said lithium chloride is administered as an adjuvant to a regenerative therapy, wherein said regenerative therapy is a gene therapy, a protein therapy, a cell therapy, or a tissue transplant. In one embodiment lithium chloride, or a salt thereof is utilized alone, or with a regenerative means, to evoke preservation and/or elongation of telomere length in pulmonary tissue.
