This is an umbrella group with over 140 member charities which are involved in medical research.

All members of the AMRC are required to ‘support the principle of using animals in research’.  https://www.amrc.org.uk/Pages/Category/research

The AMRC is less explicit about its support for the use of human embryos in research. However, in a joint statement on genome editing in human cells, the AMRC says: ‘We will continue to support the use of genome editing in preclinical biomedical research as well as studies that progress and refine these technologies. Within the UK, this research may involve the use of somatic (non-reproductive) or germ cells, including human embryos up to 14 days old - within the confines of the HFE Act 2008 - where appropriately justified and supported by rigorous scientific and ethical review.’ (Emphasis added.)

The full statement, which can be seen here https://www.amrc.org.uk/Pages/Category/genome-editing, is signed by: The Academy of Medical Sciences; Cancer Research UK; BBSRC – bioscience for the future; Medical Research Trust; Progress Educational Trust; Wellcome Trust; Wellcome Trust Sanger Institute.

Charities which are members of the AMRC pay an annual membership fee ranging from £375 - £4,495 depending on the charity’s income. https://www.amrc.org.uk/become-a-member  Even though the membership fees are small, donations to charities which are members of the AMRC could go towards the membership fee.

Charities which are part of the AMRC are supporting embryo research through their membership, even if, as in many cases, they are not directly funding projects which use human embryos.
