New North Carolina State University Study Reveals Reproducible Way to Study
Исследователи проводили биопринтинг клеток растения Arabidopsis thaliana (Резуховидка Таля) и соевых бобов, чтобы изучить, будут ли растительные клетки жить после биопринтинга и как долго. Ученым также интересно как они приобретают и изменяют свою идентичность и функции.
The root of a plant has many different typescells with specialized functions,” said researcher Lisa Van den Broek. “There are also different sets of genes that are expressed, some of them specific to each cell. We wanted to find out what happens after living cells are bioprinted and placed in a created environment.”
The process of 3D bioprinting of plant cells is mechanically similar to printing with ink or plastic, with some modifications.
"Instead of 3D printing with ink or plastic, we use 'bio-ink', living plant cells," Van den Broek said."The mechanics of both processes are the same, but there are a few noticeable differences for plant cells: UV filterto maintain a sterile environment and multiple print heads for simultaneous printing with different bio inks."
Living plant cells without cell walls,or protoplasts, bioprinted along with nutrients, growth hormones, and a thickening agent called agarose, a seaweed-based compound. Agarose helps provide cells with strength.
Scientists have survived 40% of individual soybean embryonic cells. At the same time, they were resistant to the manifestations of climate change - heat, drought and too much water.
