Cord Blood CD34+ Stem/Progenitor Cells

Cord Blood CD34+ Stem Cells

Human cord blood is a rich source of CD34+ hematopoietic stem and progenitor cells. Collection of cord blood is a noninvasive and painless procedure performed at one of our partnering hospitals by our own procurement staff. Fresh whole cord blood is transferred to our FDA registered GLP regulatory-compliant cell manufacturing facility where cord blood CD34+ stem cells are processed, analyzed, and vialed. Cell attributes, such as phenotype, viability, purity, and cell count, are checked to meet rigorous standards ensuring high-quality cells before leaving the facility.

Frequently Asked Questions

How many CD34+ stem cells can I get from a single cord?

Each cord is different and the number of CD34+ stem cells varies greatly among the individual donors. Typically, 1-4 million CD34+ stem cells per cord can be collected. We can provide larger lots upon request.

Can the cord blood be HLA typed?

Yes, upon request.

Have people used cord blood CD34+ stem cells to humanize mice?

Yes, we have many researchers that use our CD34+ stem cells to humanize mice.

What infectious disease screening is performed on cord blood?

Infectious disease screening for HIV, HBV, and HCV is performed on maternal blood. You can request to have infectious disease screening performed on the cord blood.

Can cord blood be LCMV tested?

Yes, upon request.

Can cord blood CD34+ stem cells be injected into humans?

NO, our cord blood CD34+ stem cells are for research use only and are not approved by the FDA for use in humans.
