Cells taken from umbilical cords offer three key benefits compared to cells from the patient's own body: No invasive procedure is needed to collect the cells, unlike when using stem cells from bone marrow or adipose tissue. The quantity of cells available is not restricted when using umbilical cells. In contrast, with patient-derived cells, the number of cells is limited to what's already in their tissues. Over time, autologous stem cells often lose their effectiveness and might become impaired, reducing their usefulness as a treatment. This isn't the case with umbilical cord-derived cells.
