Treatment with adipose derived mesenchymal stem cells and their conditioned media reverse carrageenan induced paw oedema in db/db mice.

Abstract

Mesenchymal stem cells are known for anti inflammatory and immunomodulatory activities. The aim of our study was to evaluate the effect of human adipose derived mesenchymal stem cells (hADMSCs) and its conditioned media (CM) on carrageenan induced acute inflammation in db/db mice. We injected 5×105 ADMSCs or the CM in the inflamed paw. We assessed the paw volume, serum IL6 levels and histopathology of the paw to reveal the anti inflammatory effect. We observed a single injection of hADMSCs or CM could reverse the inflammation within 24h as evidenced by reduction in paw volume, IL6 levels and histological examination. Our result equivocally demonstrates the role of CM in normalising the inflammation better than hADMSCs. This study will pave way for an alternative to anti inflammatory drugs.
