Why the study?

Metabolic syndrome is associated with low-grade inflammation that can be exacerbated by renal artery stenosis and renovascular hypertension, but whether mesenchymal stem/stromal cells could reduce fat inflammation in this setting remained unknown.

Does autologous adipose-derived MSC injection reduce fat inflammation in pigs with metabolic syndrome and renovascular hypertension?

Population

Twenty-four pigs

Comparison

Lean control vs MetS vs MetS + RAS vs MetS + RAS + MSCs

Preclinical animal study

Follow-up

Four weeks

Key result

Overview

MSCs reversed adipose inflammation in a porcine MetS+RAS model; leaves open translation to human cardiometabolic therapy.

Structured PICO

Does autologous adipose-derived MSC injection reduce fat inflammation in pigs with metabolic syndrome and renovascular hypertension?

P
Population
24 pigs with metabolic syndrome and renal artery stenosis, followed for 4 weeks after treatment to assess fat inflammation.
I
Intervention
Autologous adipose-derived mesenchymal stem/stromal cells (MSCs) (10^7 cells) injected into the renal artery six weeks after RAS induction.
C
Comparator
Lean (control), MetS alone, and MetS + RAS without MSC treatment.
O
Outcome
Fat volumes and inflammatory markers (including pro-inflammatory cytokines MCP-1, TNF-a, IL-6 in renal vein blood and perirenal fat, fat fibrosis, adipocyte size, and adipogenesis-related gene expression) assessed four weeks post-injection.surrogate

Autologous adipose-derived MSC therapy attenuates fat inflammation and improves metabolic outcomes in a porcine model of metabolic syndrome and renovascular hypertension.

Cite This Study

Krueger et al. (2025) studied Metabolic syndrome and renovascular hypertension (n=24). Autologous adipose-derived mesenchymal stem/stromal cells (MSCs) vs. Lean (control), MetS, and MetS + RAS groups was evaluated on Fat volumes and inflammatory markers (MCP-1, TNF-a, IL-6). Autologous adipose-derived MSCs reduced pro-inflammatory cytokines, decreased fat fibrosis, and attenuated fat inflammation in pigs with metabolic syndrome and renovascular hypertension.
