PDGFA Found to Stimulate Lung Tissue Repair in Aged IPF Mice
Pretreatment with retinoic acid was found to stimulate the repair of damaged alveoli — the tiny air sacs in the lungs — in a mouse model of idiopathic pulmonary fibrosis (IPF) by upregulating a molecule called PDGFA. The researchers used an aged mouse model to simulate the lung…
