StemExpress Cord Blood

StemExpress offers a unique opportunity for researchers to access high-quality cord blood for their projects. With strong connections to local hospitals, we can source numerous cords per week, ensuring a consistent supply of fresh and viable CD34 stem cells. Unlike our competitors who mainly rely on cord bank leftovers, our cords are collected in the maternity ward directly after childbirth offering unprecedented quality. Our expert team typically isolates CD34 stem cells within 24 hours of harvesting, resulting in millions of high-quality stem cells on average per cord. 

Collected in maternity wards for unprecedented cell counts and viability

CD34 stem cells are ideal for developing humanized mouse models with excellent engraftment rates, making them a valuable resource for the advancement of biomedical research.

  • Local hospital connections grant access to consistent cord supply
  • Collection happens moments after birth, ensuring the highest quality, quantity and viability of CD34 stem cells
  • We offer customization of vials and cell concentration
  • Millions of CD34s per cord on average
  • CD34 isolations typically occur within 24 hours of collection
