Summary

Mesenchymal stromal cells (MSC) are fibroblast-like multipotent cells capable of tissue-repair properties. Given the essentiality of tight junctions (TJ) in epithelial integrity, we hypothesized that MSC modulate TJ formation, via the AMP-activated kinase (AMPK) pathway. Liver kinase-1 (LKB1) and Ca-calmodulin-dependent protein kinase kinase (CaMKK) represent the main kinases that activate AMPK.
