Cord blood disorders is speculative, some research has been done in other areas. Any such potential beyond blood and immunological uses is limited by the fact that cord cells are hematopoietic stem cells (which can differentiate only into blood cells), and not pluripotent stem cells (such as embryonic stem cells, which can differentiate into any type of tissue). Cord blood has been studied as a treatment for diabetes. However, apart from blood disorders, the use of cord blood for other diseases is not in routine clinical use and remains a major challenge for the stem cell community. Along with cord blood, Wharton's
Ethics of technology how to treat diseases and provide families in need with the resources to cope. A version of pre-natal testing, called tandem mass spectrometry, is a procedure that "measures levels and patterns of numerous metabolites in a single drop of blood, which are then used to identify potential diseases. Using this same drop of blood, tandem mass spectrometry enables the detection of at least four times the number of disorders than was possible with previous technologies." This allows for a cost-effective and fast method of pre-natal testing. However, critics of tandem mass spectrometry and technologies like it are concerned about the
