摘 要:Dear Editor,Extracellular vesicles(EVs)derived from mesenchymal stem/stromal cells(MSCs)contain genetic and protein material that stimulate tissue repair and ameliorate injury in recipient *** of particulate MSC-EVs over MSCs in treating kidney disease include better penetration of injured glomerular filtration barrier to access podocytes or tubular ***,systemic EV delivery yields low kidney retention efficiency,limiting their regenerative benefits.1 Previously,we coated adipose tissue-derived(AD)-MSC with antibodies against kidney injury molecule(KIM)‐1(ab-KIM1),a protein upregulated in damaged kidneys.2 Conjugating ab-KIM1 did not impair MSC function but increased their retention and reparative potency in murine renal artery stenosis(RAS).2 We hypothesized that ab-KIM1 conjugation would similarly enhance retention of exogenously delivered EVs in ischemic kidneys and confer superior therapeutic benefits.
