Post-ischemic reperfusion injury (PIRI) triggers an intense inflammatory response
which is essential for repair but is also implicated in pathogenesis of
post-ischemic remodeling in several organs in human. Stem cell therapy has
recently emerged as a promising method for treatment of PIRI in human. However,
satisfactory results have not been reported due to severe loss of injected stem
cells in PIRI including critical limb ischemia (CLI). For investigating the
advanced glycation end-product-albumin (AGE-albumin) from activated macrophages
is critical in both muscle cell and stem cell death, we evaluated the recovery of
PIRI-CLI by injection of human bone marrow derived mesenchymal stem cells
(hBD-MSCs) with or without soluble receptor for AGEs (sRAGE). Our results showed
that activated M1 macrophages synthesize and secrete AGE-albumin, which induced
the skeletal muscle cell death and injected hBD-MSCs in PIRI-CLI through RAGE
increase. Combined injection of sRAGE and hBD-MSCs resulted in enhanced survival
of hBD-MSCs and angiogenesis in PIRI-CLI mice. Taken together, AGE-albumin from
activated macrophages is critical for both skeletal muscle cell and hBD-MSCs
death in PIRI-CLI. Therefore, the inhibition of AGE-albumin from activated
macrophages could be a successful therapeutic strategy for treatment of PIRI
including CLI with or without stem cell therapy.
