Cell niche homeostasis plays a critical role in many bodily functions including tissue functionality, stem cell maintenance and differentiation, wound healing, cancer development and propagation, and many others. Many tissue engineering approaches overlook the importance of engineered constructs homeostasis, in particular for transplantation purposes. Here, we present a study of the effect of encapsulation duration on engineered tissue maturation and provide a protocol for the evaluation of critical conditions for transplantation purposes. In brief, SHSY5Y human neuroblastoma cells were encapsulated in 2% alginate by electrohydrodynamic jetting method for up to 4 weeks. We evaluated extracellular matrix niche formation and tissue maturation in situ through COL1A1 expression. In in vitro conditions, we studied the ability of cells to maintain their critical functions after being released from alginate beads. Cellular viability was evaluated via an apoptosis/necrosis detection kit and AlamarBlue assay, and functionality via immunocytochemistry. We proved the importance of engineered tissue homeostasis stabilization for future cell recovery, in particular, for our system cells encapsulated for 28 days met all critical requirements for successful tissue transplantation. Maturation of engineered tissue constructs could be accelerated by enriching alginate with growth factors or extracellular matrix molecules.
