Our Technology

Our unique proprietary plant cell biomanufacturing platform is capable of identifying, isolating and cultivating plant vascular stem cells for commercial applications, which it then uses to create new solutions that can potentially be manufactured at industrial scale.

Plant Vascular Stem Cells

Plant vascular stem cells (VSCs) have the potential to differentiate into functionally and structurally distinct primary plant tissues. With the appropriate external chemical elicitation, plant vascular stem cells can be cultured to produce target bioactive molecules which are produced naturally in whole plants.

 

GBL combines significant know how and proprietary IP around the cultivation of plant vascular stem cells, including: 

Unique expertise around the patent-protected isolation and culture of higher-yielding plant vascular stem cells rather than using low-yielding dedifferentiated cells (DDC) (10X to 50X increase)

Proprietary “Yield Boost” genetic procedures to generate and identify the highest yielding plant cell culture lines (2X to 5X increase)

Proprietary identification/exploitation of molecular “gene switches” to further increase natural product yields (2X to 10X increase)

Cultivating Plant VSCs

Using GBL’s platform technology, target plant primary vascular stems cells are dissected from leaf materials from whole plants known to produce the target natural product.

 

The dissected VSCs are grown on solid media, with the appropriate nutrients and growth hormones to induce their proliferation away from their host plant.

 

Proliferated VSCs are transferred to and cultured in liquid media for further proliferation and associated scale up.

 

Unlike dedifferentiated cells, vascular stem cells are not very sensitive to mechanical shear stresses, such as shaking and stirring, in liquid culture, which can compromise oxygen/nutrient circulation and effect dedifferentiated cell growth and yield. Vascular stem cells have multiple, very small vacuoles and as such this cryopreservation effect is minimal, allowing storage at low temperature.
