Today, it was reported that a talented team of specialists in 3D printing and bio printing from Rice University was able to create a new technological process for the manufacture of artificial polysyllabic blood vessels and vascular networks from biomaterials. The result is not only looks and feels like the natural blood networks of the human body, but also functions in the same way, demonstrating approximately the same level of accuracy and ease in the delivery of air, blood, lymph and other biological fluids through all channels and arteries – this experiment was carried out on a modified model of human lungs created from hydrogel.
In the course of the experiment, scientists attempted to increase the scale and accuracy of their new technological approach and achieved truly significant success – because their independent-type complex blood network really began to demonstrate a high degree of accuracy and efficiency in the delivery of blood and other fluids through the channels. It is worth noting the fact that the system itself is a circulatory network of a closed and individual type – in other words, the network consists of many separate networks of blood vessels, which are folded together in an absolutely similar type of natural addition.
It is worth noting that the new bioprinting technology has a promising character, since preliminary tests on an air bag — the role played by the flexible lungs of a hydrogel — showed that such a technology could in fact become complex and very thin and intricate systems of blood vessels and channels — and therefore promises be one of the most functional.
In addition, for the time being, specialists are interested in enhancing the concept of multi-vascular – in other words, they are interested in not only increasing the external scale of their artificial blood supply system, but also making it more complex and florid from the inside. In case they succeed before launching the second stage of testing, this will mean the final victory in bioprinting.
