CFTR and cystic fibrosis: As previous studies have shown that CF cells display increased proliferation while wound closure (mostly migration) is impaired (Quaresma et al., 2020; Hajj et al., 2007; Trinh et al., 2012; Schiller et al., 2010), we sought to assess this here in the two CFBE cells expressing mutant CFTR in order to compare the impact of CFTR mislocalisation versus loss of function on these processes.
