Guidance on tissue types

You will need to verify the tissue and cell types that your establishment worked with between 1 January 2022 and 31 December 2022. Please select all the boxes that apply to your establishment.

Starting material for Advanced Therapy Medicinal Products (ATMPs)

If you have carried out licensable activities, such as procurement and testing, for the purposes of generating the starting material for an ATMP, please choose the relevant tissue type with ATMP in brackets from the available list. For example, if you procured adipose tissue as the starting material for an ATMP, please select ‘Adipose (ATMP)’ from the list of tissue types.

Please complete a new annual activity sheet for each tissue type that you have worked with as the starting material for an ATMP.

Acellular tissue

If you buy acellular tissue and store it for end-use only - i.e. you are not a distributor of such products - please do not submit a return for any of these tissue types.


Count each artery and vein as a separate unit.

Patches or conduits

For patches or conduits, please treat these as separate tissue types and complete a form for each.
