The first group has already been operated on, various materials have been transplanted to them, the animals are already in the vivarium.

During the experiment, surgeons make a hole in the skull of each animal with a diameter of about one and a half millimeters. It is specified that scientists have chosen such a defect due to the fact that it is one of the most difficult to heal.
Then various materials are added to the defect – octacalcium phosphates obtained in space or on Earth, or tricalcium phosphates. One group of animals does not receive any materials at all.
In total, more than 50 animals participate in the experiment, which the researchers divided into groups: the first group has already been operated on.
The restoration of bone tissue in rats will be checked first one month after the operation, then two more times – after three and six months.
One of the most important goals of the experiment is to compare space and terrestrial materials.
