Overview of nanoparticle tracking analysis from MSCs‐derived media

Cell type	Concentration of EVs (particles/mL)	Size (nm)
Bone marrow	1.87 ± 8.41 × 1010	235.9 ± 40.50
Synovial fluid	1.69 ± 2.47 × 1011	180.2 ± 64.45
Neck fat	3.88 ± 1.60 × 1010	151.2 ± 36.27
Mesenteric fat	2.43 ± 1.98 × 1010	217.8 ± 8.28
Tail fat	5.85 ± 4.36 × 1010	153.8 ± 62.24

Particles from BM cells seemed to be larger in comparison with other MSCs types. NF particles were smallest. No significant differences were observed (p > 0.05). Mean data (n = 3) are presented as average size ± SD.
