Three-Dimensional Printing and Angiogenesis: Tailored Agarose-Type I Collagen Blends Comprise Three-Dimensional Printability and Angiogenesis Potential for Tissue-Engineered Substitutes

Abstract: Three-dimensional (3D) bioprinting is a promising technology for manufacturing cell-laden tissue-engineered constructs. Larger tissue substitutes, however, require a vascularized network to ensure nutrition supply. Therefore, tailored bioinks combining 3D printability and cell-induced vascularization are needed. We hypothesize that tailored hydrogel blends made of agarose-type I collagen and agarose-fibrinogen are 3D printable and will allow the formation of capillary-like structures by human umbilical vein en… Show more

“…Here, HDFs and HNFs were compared with respect to their vascularization potential. The pro‐angiogenic effect of HDFs was shown by our group previously (Kreimendahl et al, ), but the potential of HNFs had not been verified so far. Here, HNFs revealed no significant difference in vascularization‐supportive potential making them a promising cell source for respiratory tissue engineering as they origin from the same tissue as the ciliated cells and can support their differentiation (Kobayashi et al, ).…”

“…The vascularization potential of HNFs was tested in our standard assay in fibrin gel for capillary‐like vessel formation to prove equivalency to previously established HDFs (Kreimendahl et al, ). All parameters (structure volume, area, length, and branches) confirm comparability of nasal to dermal fibroblasts (Figure ).…”
