Umbilical Cord Blood Products

For Your Cell-Based Assays

Human umbilical cord blood (CB) primary cells consist of hematopoietic stem and progenitor cells (HSPCs) as well as stromal cells or mesenchymal stromal cells (MSCs). CB-derived cells can be an advantageous choice over other cell sources in a number of research applications, such as the development of screening assays for drug discovery, regenerative cell therapies, and immune modulation. This is due to the enhanced capacity of CB-derived cells for progenitor cell proliferation, multilineage differentiation, and self-renewal in vitro. CD34+ HSPCs derived from CB are more naïve than cells derived from other tissues, making them ideal for transplantation studies and a great tool to avoid HLA mismatch issues. Using CB products in your research can also increase the physiological relevance of your cell culture systems and generate data that is more predictive of in vivo outcomes.
