Opis:
Currently developing on a large scale, the opportunities for 3D printing represent more and more perspective solutions in the area of tissue engineering and personalized medicine. Due to their ability to reproduce the natural extracellular matrix and unique properties, hydrogels are popularly used materials to produce bioinks designated for 3D printing. Today, solutions based on sodium alginate and gelatin are frequently used compositions for this purpose. The high viability of the cells incorporated into bioink is the key parameter determining the application opportunities of printed structures. The parameters of the process used for the preparation of hydrogel compositions may have a direct impact on the viability of the cells incorporated within the printed structure. This study aims to develop a protocol for the preparation of hydrogel materials based on alginate and gelatin, providing the highest viability of the model osteoblast-like cell line Saos-2 incorporated directly into the bioink before the 3D bioprinting process. In the scope of this study, the analyzed process parameters of the preparation of the hydrogel bioinks are the method of combination of a polymer solution with biological material, the applied concentration, the cross-linking solution, and also the waiting time of the prepared hydrogel bioink for the 3D printing process. A key aspect of the study is the evaluation of the influence of 3D printing on changes in the survival rate of biological material directly after the manufacturing process and after individual incubation periods of the printouts in conditions reflecting the body’s environment.

Opis:
Background: For about 20 years we have been observing the development of three-dimensional (3D) printing. The aim of this study was to systematize the current knowledge on the use of 3D printing technology in neurosurgery and to aetmpt an outline the future paths of its development. Material and methods: The analysis was based on English-language literature from 2017-2021 indexed in the Mendeley and Scopus databases. Results: The application of 3D printing in neurosurgery concerns: 1) teaching students, 2) training of residents neurosurgeons, 3) individualized surgery planning, 4) dedicated cranial and spinal implants, 5) the future of 3D printing in neurosurgical implantology. There were 5 main neurosurgery subtopics in which 3D printing was used: “vascular neurosurgery” (31%), “skull, cranial neurosurgery” (22.4%), “neuro-oncology” (19.3%), “spine” (14.3%) and “others” (13%). The number of published articles has been steadily increasing by 11-33% annually. Conclusion: 3D printing has an enormous potential for clinical use and in the we will continue to observe its dynamic development. In neurosurgery 3D prints are currently most commonly used for didactic purposes as detailed anatomical models, for training residents and young surgeons and by specialists for the simulation of complex or innovative surgeries. The future of the use of additive 3D printing in neurosurgery lies in the biological 3D printing, the creation of artifcial organs and the development of biological implants in tissue engineering.
