CD34⁺ stem and progenitor cells from umbilical cord blood are crucial for haematopoiesis and modulation of the immune response. These unique cells contribute to the formation of various blood cells, including immune effectors such as natural killer cells and cytotoxic T-cells, shaping both the adaptive and functional aspects of the immune system.

Cells were collected from from a healthy human donors using permission forms and procedures that have been approved by the Institutional Review Board (IRB).

Storage: For prolonged cell preservation or resuscitation, it is recommended to prepare the cells for extended storage in the vapor phase of liquid nitrogen. Storage of cells in the liquid phase of nitrogen is strongly discouraged to prevent potential cross-contamination risks when removing from storage. Long-term storage under −175 °C and for short-term storage, about one or two weeks at −80 °C is permitted, but it is recommended to minimise this duration to ensure optimal stability. Thawed samples should be used immediately and not stored.
