Visualizing Stem Cells At Work

What remains a question is how newborn stem cells work together to help the body heal. Researchers theorize that this diverse population of cells functions as a symphony, each type of cell having a different role to perform in healing damaged tissue and cells.

Current research suggests that newborn stem cells help orchestrate a natural repair process. Cord blood stem cells heal by helping to reduce inflammation, stimulate the growth of blood flow to injured areas, and ultimately enable injured cells to repair themselves.

Stem cells are the "master" cells of the body. They are the building blocks of all tissues and organs. Because they have the ability to develop into many different cell types, scientists are working to harness the power of these cells to repair damaged tissue, treat diseases, and boost the body's natural healing abilities. While researchers have yet to identify every type of newborn stem cell, they have isolated specific stem cells that are the building blocks for other cells and organ tissues throughout the body. Cord blood is collected because it is a rich source of these newborn "magical" cells.

Cord blood stem cells and embryonic stem cells

The umbilical cord and the blood left in it at birth contain a broad diversity of pristine newborn stem cells that have demonstrated the ability to help other tissues and organs heal themselves after injury or disease. Hematopoietic stem cells found in cord blood used for 20 years to help regenerate the body's blood and immune system. Mesenchymal stem cells, found primarily in the umbilical cord tissue itself, have the ability to help from bone or connective tissues like cartilage and ligaments.

Stem cells from the umbilical cord and cord blood have distinct benefits  compared to adult stems cells from bone marrow. They're younger, have greater ability to multiply, and have had minimal exposure to environmental factors like viruses or chemicals that can interfere with cell structure and function. 

Cord blood stem cells are not embryonic stem cells. Collecting and using them is not controversial.
