β1-integrin[2]
Pyrintegrin (0-10 μM; 1 hour; hASCs) treatment inhibits BMP4-mediated phosphorylation of BMP responsive SMAD1/5 in a dose-dependent manner (IC50 of 1.14 μM)[1].
In vitro, Pyrintegrin stimulats human adipose stem/progenitor cells (hASCs) to differentiate into lipid-laden adipocytes by upregulating peroxisome proliferator-activated receptor (PPARγ) and CCAAT/enhancer-binding protein-α (C/EBPα), with differentiated cells increasingly secreting adiponectin, leptin, glycerol and total triglycerides. Pyrintegrin attenuates Runx2 and Osx via BMP-mediated SMAD1/5 phosphorylation[1].
Treatment with Pyrintegrin prevents damage-induced decreases in F-actin stress fibers, focal adhesions, and active β1-integrin levels in cultured cells[2].

Result:Inhibited BMP4-mediated phosphorylation of BMP responsive SMAD1/5 in a dose-dependent manner.
In rats, Pyrintegrin reduces peak proteinuria caused by puromycin aminonucleoside-induced nephropathy[2].
Pyrintegrin induces postnatal adipose tissue formation in vivo of transplanted adipose stem/progenitor cells (ASCs) and recruited endogenous cells. In vivo, Pyrintegrin-treated human adipose stem/progenitor cells (ASCs) in 3D-bioprinted scaffolds, when transplanted in the dorsum of athymic mice, yielded ectopically formed adipose tissue that expressed human PPARγ. Remarkably, Pyrintegrin-adsorbed collagen gel implanted in the inguinal fat pad promoted adipogenesis formed by host endogenous cells, suggesting its ability to induce in situ adipogenesis without the need for cell transplantation[1].
