Umbilical cord blood (UCB) collected from umbilical cord and placenta following child birth, is a rich source of stem cells which are preserved and harvested for treatment of many diseases and for use in stem cell research. Efficient preservation of cord blood cells is crucial for availability of viable stem cells at the time of need. Scientists at NCCS have developed a unique technique for cryopreservation of UCB cells for banking and research.This protocol includes three stage approaches of processing, quality check and finally cryopreservation of the UCB samples.
This protocol addresses various issues related to cryopreservation of cord blood cells including prevention of cryoinjury, improving migration, adhesion and homing of cells, and protecting functionality of hematopoietic cells that are important for clinical applications such as growth factor responsiveness, preservation of surface molecules and long-term culture-forming ability.
