Figure Lengend Snippet: a, Western blot of iWAT lysate probed with anti-mNeonGreen antibody demonstrates presence of hCD81-mNeonGreen protein in iWAT tissue of both lean and obese mice (bottom row), indicating successful Cre recombination and expression of hCD81-mNeonGreen recombinant protein in iWAT tissue. There is no significant difference between normalized amount of hCD81-mNeonGreen (using vinculin as a loading control) in iWAT between lean and obese groups. b, Western blot of lysate from left atria probed with anti-mNeonGreen antibody demonstrates presence of hCD81-mNeonGreen of both lean and obese mice (bottom row), indicating presence of adipose tissue-specific EVs tagged with hCD81-mNeonGreen. c, Western blot of lysate from left ventricles probed with anti-mNeonGreen antibody (bottom row) demonstrates presence of adipose tissue-specific EVs tagged with hCD81-mNeonGreen in left ventricle (bottom row). Normalized amount of hCD81-mNeonGreen is significantly higher in left ventricles of obese compared to lean mice. (n = 3 lean mice and 3 obese mice, each with 2 technical replicates) *, p < 0.05, **, p < 0.01. d-f, Immunostaining of left ventricles of lean and obese mice demonstrated co-localization of troponin I, a cardiomyocyte marker ( d ), vimentin, a fibroblast marker ( e ), CD68, a macrophage marker ( f ), and mNeonGreen, indicating adipose tissue-specific EV deposition in these three cell types.
Article Snippet: Cells were thawed and seeded on fibronectin-coated culture vessels and were maintained in cardiomyocyte maintenance basal medium (Axol Bioscience, cat. no. ax2530) as per the manufacturer’s instructions.
