Stem Cell Banking Benefits and Insights
What are Stem Cells?
Stem cells are the body's raw materials - cells from which all other cells with specialized functions are generated. They have the ability to develop into many different cell types in the body during early life and growth. Stem cells can divide for indefinite periods in culture and have the ability to regenerate tissues damaged by diseases, injury or the aging process.
History of Stem Cell Banking
Stem cell research began in the 1960s, but intensive research started in the late 1990s. Significant developments included the discovery that mice and humans could be cloned from stem cells removed from early embryos in 1998, and the discovery of human embryonic stem cell lines in 1998. Debate increased around the moral and ethical issues associated with embryonic stem cell research. The first private cord blood bank was established in the US in 1992 and the use of cord blood stem cells for transplantation was established as a routine treatment for some cancers and blood diseases by the late 1990s.
Why Bank Cord Blood Stem Cells?
Umbilical cord blood is a rich source of Stem Cell Banking that can be collected right after birth from the placenta and umbilical cord with no risk to the mother or newborn. These stem cells carry the potential to treat over 80 diseases including cancers, blood disorders, metabolic and genetic conditions. As only the blood remaining in the placenta and cord after birth is collected, cord blood stem cell collection is considered low-risk for mother and child compared to other sources. Banking these cells offers potential therapeutic options should the child or a family member require a stem cell transplant in the future.
Stem Cell Research Directions
Major recent developments in stem cell research include generation of induced pluripotent stem cells (iPSCs) from adult tissues, use of modified mRNA reprogramming techniques not involving genetic modification, isolation of organ-specific stem cells offering targeted therapy options, enhancement of stem cell collections using hypoxic techniques, better understanding of molecular mechanisms of reprogramming and differentiation and development of 3D bioprinting techniques combining multiple cell types. These advances offer immense hope for developing regenerative therapies for many intractable diseases in the future.
Stem cell banking offers potential benefits by preserving valuable therapeutic stem cells, especially cord blood stem cells collected at birth with minimal risks. While still limited by technological and clinical constraints, ongoing research continues advancing application of stem cells. Careful consideration of options like public versus private banking allows families to make informed choices balancing risks, costs and benefits in light of one's circumstances and the humanitarian philosophy of sharing life-saving resources. Continued progress depends on further supporting scientific studies in this promising field of medicine.
