Russian scientists have invented biromaru for growing living organs


Biromaru for printing living human organs developed by the staff of the Institute of theoretical and experimental Biophysics, Russian Academy of Sciences in Pushchino near Moscow.

As reported by “MK” at the Institute, bioprinting or 3D printing of organs is essentially similar to the technology used in conventional printers. Has inkjet technology in which ink is used as cellular on steroids. They’re balls of cells that, if placed together in a certain order, create any biological structure or organ. There is also laser print technology bodies, in which the migration of individual cells on a substrate is exposed to a special laser. In both cases, in order to provide the cells life during these manipulations of the printing, they require an appropriate microenvironment, which scientists call a rather arbitrary bionomial by analogy with ordinary paper from the printer.

Biomega or, as it is called experts – the hydrogel is created from proteins, polysaccharides and other organic components, which creates around the migrated cells the necessary environment. “Biobodies” you can “wrap” the cage prior to transfer to the “substrate” (for example, ordinary glass) for its better preservation, but you can make it in the form of a gel film, which are implantable cells. Depending on a given program, this environment will help to implement the intercellular interaction or migration — migrating cells in the desired area for the proper cultivation of an organ.

Currently, the Institute staff has developed various types of boobology for growing them of the endocrine glands, blood vessels and bone tissue.
