What is human umbilical cord blood?
Cord Blood
Human umbilical cord blood contains unique stem cells with the remarkable potential to develop into various cell types, offering significant benefits for tissue repair and regeneration. These stem cells can divide and renew themselves, supporting the maintenance and repair of tissues. Umbilical cord blood is a rich source of hematopoietic stem cells (HSCs/CD34+), which have the capacity to form essential blood and immune cells, making them valuable in treating blood disorders and strengthening immune function. Unlike adult stem cells, which are found in various tissues, umbilical cord blood stem cells are readily available at birth and provide a powerful, non-invasive resource for potential therapeutic applications.
Cord Blood
Cord blood collected from the umbilical cord and placenta after childbirth, is a rich source of hematopoietic stem cells (HSCs), mesenchymal stem cells (MSCs), and various growth factors. Cord blood HSCs, particularly CD34+ stem cells, are considered to have a more naive state, with research suggesting they may exhibit higher proliferative, engraftment, and multipotent potential compared to those from adult bone marrow.
Adult HSCs in the body may face challenges related to delivery systems and the host’s health, including aging. Tissues with limited blood supply, such as tendons and ligaments, may not readily benefit from HSCs without invasive procedures like bone marrow harvesting. Aging and certain disease states have been associated with potential reductions in the bioactivity, engraftment, and proliferation of autologous (self-sourced) cells.

What are Growth Factors and why are their presence in cord blood fluid significant?
Growth Factors
Growth factors are naturally occurring proteins or peptides that play a crucial role in regulating cellular processes such as proliferation, differentiation, and survival. They act as signaling molecules, binding to specific receptors on the surface of target cells and triggering a cascade of cellular activities essential for growth and development. Growth factors are often utilized to promote tissue repair, enhance wound healing, and support the growth of cells in culture.
While the benefits of specific growth factors are recognized, many work in concert with others to support biological processes. The use of individual peptides may not achieve the full potential of coordinated growth factor activity. Cord blood fluid contains a variety of growth factors that interact with one another, and research is exploring their potential role in supporting tissue growth and repair, as well as creating an environment that may facilitate cell activity.
