Rheological and cell viability data for MFC/ALG bioink formulations used in extrusion-based 3D bioprinting of umbilical cord mesenchymal stem cells

This dataset contains the raw and processed data supporting the findings reported in the manuscript "Rheological characterisation and biological assessment of hydrogels based on sodium alginate and microfibrillated cellulose for 3D bioprinting in regenerative medicine" (Pánik et al., submitted to Annals of Biomedical Engineering). The dataset includes: (1) raw rheological data from rotational flow curve measurements, amplitude sweep, frequency sweep, and ionic cross-linking kinetic experiments for seven MFC/ALG formulations at 2.5% (w/v) total dry matter concentration; (2) Herschel-Bulkley model fitting parameters for flow curves and viscosity curves (Supplementary Tables S1–S2); (3) exponential growth fitting parameters for storage modulus G' and loss modulus G'' during CaCl₂ cross-linking (Supplementary Tables S3–S4); and (4) raw cell viability data (trypan blue exclusion assay) for printed and non-printed MFC/ALG constructs containing encapsulated umbilical cord-derived mesenchymal stem cells (UC-MSCs), assessed on days 1 and 7 post-fabrication. All experiments were conducted at the laboratory facilities of Cord Blood Center, s.r.o., Bratislava, Slovakia. This work was supported by VEGA Grant No. 1/0634/25.
