Energy-making chloroplasts from algae have been inserted into hamster cells, enabling the cells to photosynthesize light, according to new research in Japan. It was previously thought that combining chloroplasts (chlorophyll containing structures in the cells of plants and algae) with animal cells was not possible, and that the chloroplasts would not survive or function. However, results showed that photosynthetic action continued for at least two days. This technique could be useful for artificial tissue engineering. Tissues can struggle to grow due to a lack of oxygen, but adding chloroplast-infused cells could enable oxygen and energy to be supplied through light exposure and photosynthesis.
