👉 Donor fluid, often referred to as umbilical cord blood or cord tissue, is a rich source of hematopoietic stem cells (HSCs) and other cell types that can be used for regenerative therapies. Collected from the umbilical cord and placenta after childbirth, this fluid contains a high concentration of stem cells that are capable of developing into various blood cell types, making it valuable for treating conditions like leukemia, lymphoma, and other blood disorders. Additionally, donor fluid contains other beneficial components such as growth factors and cytokines that can support tissue repair and immune function, thus offering a promising alternative to traditional bone marrow transplants.
