Researchers in Boston used spinach as a scaffold to grow cultured meat, in an advancement they say could increase the production of cultured meat to match rising demand.

Spinach could be key to increasing cultured meat production

 

Spinach, a cost-efficient and environmentally friendly scaffold, provided an edible platform upon which a team of researchers led by a Boston College engineer has grown meat cells, an advance that may accelerate the development of cultured meat, according to a new report in the advance online edition of the journal Food BioScience.

Stripped of all but its veiny skeleton, the circulatory network of a spinach leaf successfully served as an edible substrate upon which the researchers grew bovine animal protein, said Boston College Professor of Engineering Glenn Gaudette, the lead author of the new study. The results may help increase the production of cultured meat products to meet rising demand and reduce environmental costs.

“Cellular agriculture has the potential to produce meat that replicates the structure of traditionally grown meat while minimizing the land and water requirements,” said Gaudette, the inaugural chair of Boston College’s new Engineering Department.

“We demonstrated that decellularising spinach leaves can be used as an edible scaffold to grow bovine muscle cells as they develop into meat.”

Gaudette said the team, which included Worcester Polytechnic Institute graduate students Jordan Jones and Alex Rebello, removed the plant cells from the spinach leaf and used the remaining vascular framework to grow isolated cow precursor meat cells. The cells remained viable for up to 14 days and differentiated into muscle mass.

“We need environmentally and ethically friendly ways to grow meat in order to feed the growing population,” said Gaudette. “We set out to see if we can use an edible scaffold to accomplish this. Muscle cells are anchorage dependent, meaning they need to grab on to something in order to grow. In the lab, we can use plastic tissue culture plates, but plastic is not edible.”

The researchers point out that the successful results will lead to further characterisation of the materials and scientific processes to better understand how to meet consumer demand and gauge how large-scale production could be accomplished in accordance with health and safety guidelines.

“We need to scale this up by growing more cells on the leaves to create a thicker steak,” said Guadette. “In addition, we are looking at other vegetables and other animal and fish cells.”
