Product Specification

Product Description

Lolina? Human UC-MSC Cool-Exo? Enhancer kit 3 is a set of sterile powders or concentrated solution which contains growth factors, hormones, or proteins for significant induction of anti-inflammatory paracrine secretion.

As an treatments additive for UC-MSC in vitro culture, this supplement has been proved has following functions:

1.         Strongly active the paracrine secretion of anti-inflammatory exosomes. Significantly inhibited the pro-inflammatory factors IL-1β and TNF-α and decreased the relative gene expression of IL-1β, TNF-α and iNOS, while promoting the anti-inflammatory factor IL-10 and increasing the relative expression of IL-10 and Arg-1 in vitro compared with PBS, LPS and Exo groups.

2.         By regulating the expression of apoptosis-related genes (such as Bcl-2 and Bax), it inhibits cell apoptosis and promotes cell survival.

3.         The robustness of exosomes can be increased by enhancing the robustness of the exosome membrane.

4.         Enhance the stress response pathway within MSCs to improve the robustness of exosomes.

5.         The generated Exosomes have a significant pro-healing effect on diabetic wounds.

Components

Instructions for Use

1. Stock solution Preparation.

One kit is for 50ml cell culture medium.

The compounds are offered as lyophilized powder, their stock solutions are prepared as follows:

a.         The compounds are offered as powder/liquid in tubes. Please centrifuge before opening the cap to ensure the accuracy of the dosage.

b.         Please carry out dissolution and packaging operations on a clean bench.

c.          Spray the medium bottle and supplement tube with 70% ethanol and wipe to remove excess liquid. In a sterile field, remove the caps without touching the interior  threads  with  fingers.

e.          Reconstitute NaC20120507-B in 100 μl sterile 1 ×PBS. Aliquot into appropriate volumes of storage solution. Aliquot into appropriate volumes of storage solution. When stored at -20℃, the stock solution is stable for 6 month. When stored at 4 ℃, the stock solution is stable for 1 week.

f.         Reconstitute NaC20120507-C in sterile 0.9% NaCl solution. The recommend volume is 5 mL. Aliquot into appropriate volumes of storage solution. When stored at 2-8 ℃, -20℃, the stock solution is stable for 24 month.  

2. Protocol

Step 1: UC-MSC Culture

Seeding: Seed UC-MSC in culture flasks or plates at a density allowing them to reach 70-80% confluence.

Growth: Allow UC-MSC to grow until they reach the desired confluence.

Step 2: Treatment UC-MSC with NaC20120507

Prepare Treatment Medium:

a.         Add the stock solution of NaC20120507to the regular culture medium to obtain a treatment medium. The dilution ratio is: NaC20120507-A/B  1:500; NaC20120507-C  1:10.

Treat UC-MSCs:

b.        Replace the regular culture medium with the treatment medium.

c.         Incubate the UC-MSCs with the treatment medium for 24 hours under standard culture conditions (37 ℃, 5% CO2).

Step 3: Post-Treatment Handling

Remove Treatment Medium: After 24 hours of treatment, remove the treatment medium.

Wash MSCs: Wash the cells gently with PBS to remove any residual the treatment medium.

Conditioning Phase:

a.         Replace with fresh, serum-free, or exosome-depleted medium.

b.        Incubate the UC-MSCs for an additional 24-48 hours to collect the conditioned medium containing exosomes.

Step 4: Exosome Isolation and Purification

Collect the conditioned medium after the post-treatment incubation period.

Note

If handled improperly, some components of the medium may present a health hazard. Take appropriate precautions when handling it, including the wearing of protective clothing and eyewear. Dispose of properly.
