Generation and characterization of PDGFRα-GFP knock-in mice for visualization of PDGFRα+ fibroblasts in vivo

Biochem Biophys Res Commun. 2023 Dec 20:687:149215. doi: 10.1016/j.bbrc.2023.149215. Epub 2023 Nov 4.

Abstract

The platelet-derived growth factor (PDGF) and its receptor, PDGFRα, are critical for tissue development and injury repair. To track PDGFRα-expressing cells in vivo, we generated a knock-in mouse line that expresses green fluorescent protein (GFP) under the control of the PDGFRα promoter. This genetic tool enabled us to detect PDGFRα expression in various organs during both neonatal and adult stages. Additionally, we confirmed the correlation between endogenous PDGFRα and transgenic PDGFRα expression using mouse injury models, showing the potential of this genetic reporter for studying PDGFRα-mediated signaling pathways and developing therapeutic strategies. Overall, the PDGFRα-GFP knock-in mouse line serves as a valuable tool for investigating the biology of PDGFRα and its role in normal development and disease.
