For example, cluster 0 that was predominant in control samples expressed higher levels of the antiproliferative genes Fos(p55) and Itih5, but also Col4a2 and Lama2. Cluster 4 was characterized by the expression of Fbn1 while cluster 5 was characterized by the expression of Lum and could confirm the existence of this population of FAPs in DMD patients recently described by Rubinstein et al. [44]. Here, LUM is linked to Duchenne muscular dystrophy.
