When a baby is born, the umbilical cord is clamped and cut. The remaining blood in the cord and placenta is collected, processed, and stored in a public cord blood bank. This involves several steps:
1. Collection: After delivery, healthcare providers collect the umbilical cord blood. 2. Processing: The collected blood is processed to extract the stem cells. 3. Testing: The stem cells are tested for infectious diseases and genetic abnormalities. 4. Storage: The processed and tested stem cells are cryopreserved in liquid nitrogen for future use.
