Collection and Preservation:

Collection Timing: Collected immediately after fetal delivery and umbilical cord clamping
Collection Volume: Typically 50-200 ml of umbilical cord blood can be collected
Preservation Conditions: Requires preservation under low temperature conditions
Preservation Period: Cryopreservation can last for decades
