According to the Kyodo News Agency, a research team at the Institute of Production Technology at the University of Tokyo announced on the 30th that it has successfully produced artificial human fingers through white mouse skin cells.
The team wrapped the cells outside a capsule made of colloidal collagen with a diameter of about 0.1 mm and injected 10 million capsules into a finger-shaped mold about 3 cm long. When removed from the mold after about 24 hours, the cells adhered to each other to form the shape of a finger. Although there are no internal structures such as bones, blood vessels and muscles in the simulated finger, this technology is expected to be used for regenerative medicine.
Researchers will investigate the function and state of cells in simulated fingers in the future. The team successfully produced a doll shape of about 5 mm long using about 100,000 identical capsules last year. Associate Professor Takeuchi Takeuchi said: "I hope to use all kinds of cells in the right place to make more realistic human tissue."
