Abstract
Gelatin methacrylate (GelMA) hydrogel is a promising bioink for biofabrication applications due to its cost-effectiveness, ease of synthesis and biocompatibility to allow cell adhesion. However, the GelMA synthesized from a widely used porcine skin gelatin has a thermal gelation problem at room temperature. Here, we present thermally stable GelMA hydrogels at room temperature while maintaining the mechanical and biological properties comparable to porcine GelMA. The novel GelMA hydrogels were synthesized from fish skin and cold soluble gelatin. We systematically characterized the properties of the GelMA hydrogels from different sources. The properties include the degree of methacrylation, compressive Young's modulus, mass swelling ratio, viscosity, and cell adhesion and proliferation in 2D and 3D microenvironments. It has been found that the cold soluble GelMA was comparable to the porcine skin GelMA but could offer low viscosity and thermal stability at room temperature. We performed a droplet generation experiment to demonstrate the benefit of using the cold soluble GelMA for biofabrication. The cold soluble GelMA showed a more reliable and stable droplet fabrication process. Taken together, the cold soluble GelMA is a promising bioink solution and may greatly benefit the research in biofabrication.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
