Regenerative medicine 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 a routine clinical modality and remains a major challenge for the stem cell community. Along with cord blood, Wharton's jelly and the
Classification of mental disorders of scores across different dimensions. DSM-5 planning committees are currently seeking to establish a research basis for a hybrid dimensional classification of personality disorders. However, the problem with entirely dimensional classifications is they are said to be of limited practical value in clinical practice where yes/no decisions often need to be made, for example whether a person requires treatment, and moreover the rest of medicine is firmly committed to categories, which are assumed to reflect discrete disease entities. While the Psychodynamic Diagnostic Manual has an emphasis on dimensionality and the context of mental problems, it has been structured largely as
