Scientists in Japan have created hybrid plant-animal cells, essentially making animal cells that can gain energy from sunlight like plants. The breakthrough could have major benefits for growing organs and tissues for transplant, or lab-grown meat.
Animal and plant cells have different energy-producing structures inside them. For animals, that’s mitochondria, which convert chemical energy from food into a form that our cells can use. Plants and algae, meanwhile, use chloroplasts, which perform photosynthesis to generate energy from sunlight to power their cells.
In a new study led by the University of Tokyo, the team inserted chloroplasts into animal cells, and found that they continued to perform photosynthetic functions for at least two days. The chloroplasts were sourced from red algae, while the animal cells were cultured from hamsters.
