Abstract
Poor cell survival in vitro and in vivo is one of the key challenges in tissue engineering. Prosurvival therapeutic proteins, such as insulin-like growth factor-1 (IGF-1), can promote cell viability but require controlled delivery systems due to their short half-lives and rapid clearance. Biocompatible materials are commonly used for drug delivery platforms or to encapsulate cells for increased viability, but few materials have been used for both applications simultaneously. In this work, we present a dual-use platform. A blend of hyaluronan and methylcellulose, known to promote cell survival, was covalently modified with Src homology 3 (SH3)-binding peptides and demonstrated tunable, affinity-based release of the prosurvival fusion protein SH3-IGF-1. The material also significantly increased the viability of retinal pigment epithelium cells under anchorage-independent conditions. This novel platform is applicable to a broad range of cells and protein therapeutics and is a promising drug delivery/cell transplantation strategy to increase the viability of both exogenous and endogenous cells in tissue engineering applications.

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
