Bioprobe was immobilized on the tapered optical fiber using ethyl cellulose by a simple dip-coating method and investigated for multi-color imaging applications. The resulting tapered optical fiber achieved a satisfactory detection limit of 46.4 nM in the dopamine concentration range of 0-10 μM. The bioprobe demonstrated high biocompatibility, long-lasting photostability, and thermal stability, and had sufficient cytotoxicity in human neuroblastoma cells (SH-SY5Y) with excellent multi-color imaging potential. The practicality of the bioprobe was investigated in human serum and cerebrospinal fluid.In tissue regeneration, the goal is to regenerate tissue similar to what was damaged or missing while preventing fibrotic scarring, which may lead to decreased mechanical strength and dissimilar tissue characteristics compared to native tissue. We believe collagen orientation plays a critical role in wound contraction and scarring and that it is modulated by myofibroblasts. We used macrophage conditioned medium to simulate complex events that can influence the fibroblast phenotype during the wound healing process. In addition to examining the effect of macrophage phenotype on fibroblasts, we inhibited focal adhesion kinase (FAK), Rho-associated protein kinase (ROCK), and myosin II for fibroblasts cultured on both tissue culture plastic and methacrylated gellan gum to understand how different pathways and materials influence fibroblast responses. Collagen orientation, α-SMA expression, focal adhesion area, and cell migration were altered by inhibition of FAK, ROCK, or myosin II and macrophage phenotype, along with the substrate. An increase in either focal adhesion area or α-smooth muscle actin (α-SMA) expression correlated with an aligned collagen orientation. Gellan gum hydrogels upregulated α
