Stem cell research

The coding for stem cell research will depend on the intention and nature of the research.

Basic developmental biology or a study of normal stem cell differentiation should be coded within the 1 Underpinning code group.

Stem cell research involving development, differentiation or transplantation of stem cells directly associated with therapeutic application should be coded as 5.2 Gene therapy or 6.2 Gene therapy. The development of stem cell lines for potential therapeutic studies should be coded as 5.2 Gene therapy.

5.4 Surgery and 6.4 Surgery do not apply to studies of cell therapy transplanation. An exception to this is surgical transplantation of bone marrow stem cells for cancer treatment, which is considered a similar process to organ transplantation, and should therefore be coded as 5.4 Surgery or 6.4 Surgery.
