Marketing materials and/or communications from multiple companies vending FDA 361 registered amniotic tissues claim that these

products contain viable stem cells. Many physicians who purchase these products for injection have web-sites that refer to these

injections as “stem cell therapy”.

Can Amniotic Products Help Human MSCs?

Page 12: Amniotic Stem Cell Products Testing Interventional Orthopedics Foundation

Human bone marrow MSCs from several donors were seeded with various amniotic products to observe:

• Morphology• Proliferation-PicoGreen DNA Assay• Metabolic activity (Alamar Blue)• Reactive Oxygen Species (ROS)-A test of cell stress and

overall health

If the amniotic tissues were causing the MSCs to proliferate more, then total DNA volume would be higher than CCM (Complete Culture Medium). This does happen when serum free (low growth factor) media is used. However, these effects are largely washed out when high growth factor culture media (platelet lysate) is used. This could indicate that while there are active growth factors in these products, but that these GF levels are likely less biologically active than those found in platelets.

If the amniotic tissues were helping the MSCs, then metabolic activity would be higher than CCM (Complete Culture Medium). Here it is generally lower.

If the amniotic tissues were helping the MSCs, then metabolic activity would be higher than CCM (Complete Culture Medium). Here it is generally lower, only AmnioFix helps and only when bovine serum is used as a culture media.

If the amniotic tissues were helping the MSCs, then ROS would be lower than CCM (Complete Culture Medium). Here it is generally the same or higher.

Conclusions:• The amniotic products tested:

• Don’t contain viable stem cells or other viable cells once they’re thawed per the manufacturer's recommendations.

• Do likely contain some active growth factors that can have a positive proliferation effect on MSCs, but those GFs in this experiment look like they are less effective than those found in platelets.

• Don’t generally help the metabolic activity of MSCs.• Don’t generally help MSCs show less oxidative stress.
