Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Large bioprinted tissues (dm 3 ) are more and more accessible but their in vitro culture and maturation conditions stay an unchartered territory. In the present report, we aim to present a preliminary study of endothelialized large bioprinted tissues (fibroblast and human dermal microvascular endothelial cells) maturation using silicone 3D printed perfusion system (bioreactor). Computational Fluid Dynamics (CFD) simulation was used to relate the theoretical culture medium flow path within the large bioprinted tissue with the actual tissue morphology and composition, obtained through histological observations. The obtained results demonstrate the positive impact of using dynamic maturation conditions (300 mL/h culture medium flow rate) on the extracellular matrix production and the conservation of the large bioprinted tissue internal geometry. Clear differences between static and dynamic culture conditions were herein found. Finally, typical microvascular organization, composed of human dermal microvascular endothelial cells organized around an open lumen, were found within the large bioprinted tissue.
