(2) In addition to these aforementioned MSCs, whether other well-recognized MSCs that are expressed in other mechanosensory cells (e.g., transmembrane channel 1/2 (TMC1/2) expressed in inner ear hair cells) and new candidates for MSCs (e.g., TACAN and Elkin1) [23, 131, 132] are involved in the pathogenesis of ALI/ARDS needs further investigation. Here, TMEM87A is linked to acute respiratory distress syndrome.
