Viability A,C) and DNA content B,D) of hTERT‐MSC in printed and crosslinked scaffolds—first experiment. Viability was determined after 1, 7, 14, and 21 days of cultivation (n = 3 of three individual samples, n = 9 in total; mean ± SD) and DNA content was measured after 1, 7, and 21 days of cultivation (n = 3, mean ± SD). hTERT‐MSC‐laden Plasma‐Alg‐MC bioinks were used for bioprinting immediately after preparation (W0) and at different time points of bioink storage at 4°C (W1–W4); the bioinks were brought to room temperature before bioprinting. Due to a contamination, DNA quantification was not possible for the W1 group for both, PBS‐Alg‐MC and Plasma‐Alg‐MC, at day 7. ^* p < 0.05, ^** p < 0.01, ^*** p < 0.001, ^**** p < 0.0001, and ns = not significant.
