UKCRC Health Research Classification System

6.2 Cellular and gene therapies

Main inclusion criteria

Clinical application and evaluation of cellular, tissue and gene therapies in humans including:

  • small scale and pilot studies
  • phase I, II, III and IV trials
  • gene therapy, stem cell therapy, in vitro fertilisation, tissue engineering
  • evaluation of applied delivery systems


Advice on research activities

This code is suitable for studies involving stem cell therapies, particularly tissue regeneration or repair of damaged tissue, in clinical and applied settings.

Cell therapy can often involve a transplantation process but they should not be coded as 6.4 Surgery too. 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 6.4 Surgery.

Excludes basic developmental biology of stem cell fate which should be coded as 1.1 Biological.
