Lum+ FAPs were the ones expressing the highest levels of collagen related genes such as Col1a1 or Col3a1. Two of the clusters identified, cluster 3 and 6, were almost exclusively present in DMD samples and were characterized by the expression of genes involved in cell proliferation such as Ahnak, Ccdc102b, and Podn or Parp14, Bod1l1 or Smg1 respectively. The gene discussed is PARP14; the disease is Duchenne muscular dystrophy.
