Human Nose


Design of Blueprint

Software used to draw 3D model

Name of software

A 3D model of a human nose was segmented and reconstructed from CT images using 3D Slicer software. The STL file of the nose model was processed in the software Slic3r (v1.2.9) and scaled to 50% of the original size. Organ Simple was selected as the print setting. This profile prints the perimeter and infill of a 3D models with printhead 1 (PH1)

Cell type(s)

Human primary nasal chondrocytes (hNC)

Cell concentration

20x106 cells/ml
A suspension of 72x106 hNCs in a volume of 600µL were mixed with 3mL of CELLINK bioink using the CELLMIXER to obtain a final concentration of 20x106 cells/ml.

Culture media composition

Culture medium: DMEM/Ham's F-12 (1:1, Biochrom), supplemented with 10% fetal bovine serum (Biochrom) and 1% penicillin–streptomycin

Differentiation medium: StemMACS ChondroDiff media (Miltenyi Biotec GmbH) supplemented with 1% penicillin–streptomycin.

Crosslinking process of bioink

After the bioprinting process, the hNC-laden nose constructs were crosslinked by submerging in an ionic solution of 100mM CaCl2 for 10 minutes. The constructs were then rinsed and incubated in culture medium in standard culture conditions (37°C, 5% CO2 and 95% relative humidity).
