Thank you for contacting me about human-specific research techniques.
The Government actively supports and funds the development and dissemination of techniques that replace, reduce and refine the use of animals in research (the 3Rs), including those specific to humans. This is achieved primarily through funding for the National Centre for the 3Rs (NC3Rs), which is organised through the UK Research and Innovation (UKRI) body. Since it was established, the NC3Rs has invested £77 million in research and almost £27 million in contracts through its CRACK IT Challenges innovation scheme.
