Autosomal recessive mutations in Pendrin (PDS/SCL26A4 ) were described in 1997 to cause Pendred syndrome [1]. However, over the years patients with either only heterozygous or even no mutation in PDS/SLC26A4 have been diag...

To read the full abstract: Nature 2020;579:111–117.In brief: In large fracture calluses, skeletal progenitors activate the chondrogenesis program, whereas in smaller calluses, direct osteogenesis is the preferred path. Here, the authors show that lipid availability determines whether skeletal stem cells repair a fracture through endochondral bone formation or direct ossificati...
