Extracellular vesicles
from bone marrow-derived MSCs
Extracellular vesicles (EVs) play an essential role in cellular communication by transporting proteins, lipids as well as nucleic acids. EVs from our bone marrow-derived mesenchymal stromal cell line BM-MSC/TERT292 are characterized by the typical EV morphology, presence of EV marker proteins as well as anti-inflammatory and anti-fibrotic activities.
General information
Cat#: EV-CHT-063-0292-A1 (5 x 10^9 EVs in 150 µl) | EV-CHT-063-0292-A2 (1 x 10^10 EVs in 300 µl)
Presence of typical EV surface marker proteins
EVs derived from BM-MSC/TERT292 cells carry typical surface proteins such as CD81, CD9 and CD63 as demonstrated using CD81+ bead-based flow cytometry. Delta mean fluorescence intensity (DMFI) was calculated by normalizing to MFI of control beads.
Anti-inflammatory activity of extracellular vesicles from
BM-MSC/TERT292
Treatment of mouse macrophage cells (RAW264.7) with lipopolysaccharide (LPS) induces the formation of nitric oxide (NO) indicating an inflammatory reaction. Addition of the positive control Dexamethasone (Dexa) significantly reduces NO secretion.
Similarly, addition of EVs derived from BM-MSC/TERT292 cells significantly reduces NO formation indicating an anti-inflammatory activity of the EVs.
Anti-fibrotic activity of extracellular vesicles from
BM-MSC/TERT292
Treatment of human fibroblasts (fHDF/TERT166) with Transforming Growth Factor beta (TGF-ß1) induces the expression of alpha smooth muscle actin (α-SMA) indicating myofibroblast differentiation/activation, which is a key event in physiological and pathological tissue repair.
Addition of EVs derived from BM-MSC/TERT292 cells significantly reduces α-SMA induction, indicating an anti-fibrotic activity of the EVs.
PP2, a Src-kinase inhibitor, is used as positive control.
FAQs
Upon arrival immediately transfer the product to -80°C.
Store product at -80°C (for up to 6 months) until use.
Thaw the EVs on ice, centrifuge before opening the tube to ensure that the solution is collected at the bottom of the tube. Then, mix carefully by pipetting up and down and aliquot for further use to avoid multiple freeze thaw cycles.
Store the aliquots at -80°C until use.
After thawing, store the EVs at 4°C for a maximum of 1 day.
