  • Cell potency is the quantitative measurement of cell proliferation potential. This, in turn, is a measure of cell primitiveness and cell engraftment potential.
  • Cell potency predicts a specific response associated with the intended effect. This is usually the capacity of cells to home, seed and begin proliferation at a particular location in the body. Cell potency does not predict whether the cells will actually differentiate and produce functional mature cells.
  • To determine identity, purity and strength (potency) of native or expanded MSCs from any source and multiple species.
  • An ATP bioluminescence, reference standard-based potency assay for MSC/MPC manufactured and produced for clinical use.
  • Determines population doubling time (PDL), viability, proliferation ability (quality) and proliferation potential in addition to potency in a single assay.
  • Includes additional standards and controls which, together with the reference standard, allows the assay to be validated.
  • Customize the assay with either CRUXRUFA™ Human Platelet Lysate GM or GMP+Q grade, serum-free/xeno-free or humanized MSCGro™ Medium. 
  • Compliant with FDA regulations for potency assays.
  • Uses the "Slope-Ratio Concentration-Response Model" to determine the measure of potency, the potency ratio, standardized in the U.S. Pharmocopeia.

Principle of ATP Bioluminescence Cell Proliferation Assays

All ATP bioluminescence assays kits from Preferred Cell Systems™ include an ATP standard(s) and controls.  Performing the ATP standard curve and controls is highly recommended. The controls are used to calibrate the instrument and the ATP standard is used to standardize the assay. The values obtained provide the measurement assurance parameters that allow you, the user, to ensure that the results obtained can be trusted.

An example of an ATP standard curve and control results are shown in the diagram below and actual values for the kit being used are given in the Technical Manual. If the values obtained are within the ranges given in the Technical Manual, the user can process the samples knowing that the results will be trustworthy.

Difference between MSCGlo™ Potency and MSCGlo™ RS

To measure potency, a reference standard of the same material as the sample is required so that the potency ratio can be determined. The inclusion of a reference standard to measure potency is an FDA requirement. Universal or global reference standards for cell therapy products are not available. As a result, it is necessary for individual centers to establish their own reference standards.

MSCGlo™ RS is used to establish your first in-house reference standard. The assay includes a vial of cord blood, peripheral blood or bone marrow cryopreserved cells that are used to compare to your own preparation. MSCGlo™ RS is only required once to set up your first reference standard cell preparation. All further reference standards establish in-house will be compared to the previous reference standard. 

To measure potency of your samples prior to use, MSCGlo™ Potency is used. MSCGlo™ Potency does not include reference standard material. You will use an in-house reference standard to measure the potency ratio of the sample.

(a): Prior to measuring potency, a reference standard (RS) must be established to which the sample can be compared and the potency ratio determined. If the MSC source is different, e.g. adipose tissue, use MSCGlo™ Potency to establish a RS for that tissue.

(1): If the MSC source is not cord blood or bone marrow, use MSCGlo™ RS to establish a reference standard (RS) for that tissue source. A RS must always accompany a sample when potency is measure, since the potency ratio can only be determined by comparion of the sample with a RS.

(2): One RS must always be performed when an unknown sample is measured. If more than 1 sample is to be measured, a single RS of the same cell type can be used to compare with all samples performed on the same day.
