Plant vascular stem cells (VSCs) can adapt into functionally and structurally distinct primary plant tissues. Using our expertise to create the right environment, plant vascular stem cells can be cultured to produce target bioactive molecules which are produced naturally in whole plants.

Our Founder

Our late founder, Professor Gary Loake, formed Green Bioactives (GBL) with a vision to revolutionise sustainable plant-based solutions. As a professor at the University of Edinburgh, his commitment to addressing the challenges in sourcing natural plant products economically and sustainably shaped our mission.

Gary's journey with GBL began during his tenure at the Institute for Molecular Plant Sciences and the Centre for Engineering Biology at the University of Edinburgh. Recognising the need for a more efficient approach, he founded GBL in 2019, aiming to revolutionise the way natural ingredients are sourced through innovative plant cell culture technology.

Originally from the West Midlands, Gary had been based in Edinburgh for over 28 years, where he made significant contributions to plant sciences. His legacy extends beyond his professional achievements, as his warmth, kindness, and optimism touched the lives of all who knew him.

Inspired by Gary's vision, we are dedicated to honouring his commitment to excellence and sustainability. At Green Bioactives, we strive to fulfil his dream of becoming a global leader in plant cell culture-derived natural products, guided by his enduring spirit of innovation.
