FIGURE 4.
Muscle injury triggers a fast and strong downregulation LPA receptors in fibro-adipogenic progenitors. (A) Violin plots showing the gene expression level of LPAR family members and dynamics in response to injury. DPI, Days post-injury. (B) Heat map showing gene expression levels of Lpar, Enpp2, and Plpp genes in Hic1+ tdTomato expressing cells upon acute muscle damage (Scott et al., 2019). (C) Quantification of Lpar (1–6) genes transcript abundance (FPKM) in Hic1+ tdTomato expressing cells and dynamics in response to injury.
