Neuron development and function are exquisitely sensitive to the mechanical properties of their surroundings. Three-dimensional (3D) cultures are therefore being explored as they better mimic the features of the native extracellular matrix. Limitations of existing 3D culture models include poorly defined composition, rapid degradation, and suboptimal(More)
Photo-cross-linking of tyramine-substituted hyaluronan (HA-Tyr) hydrogels is demonstrated for the first time. HA-Tyr hydrogels are fabricated via a rapid photosensitized process using visible light illumination. Nontoxic conditions offer photoencapsulation of human mesenchymal stromal cells (hMSCs) with high viability. Macroscopic gels can be formed in less(More)
Hyaluronan (HA) is an essential component of the central nervous system's extracellular matrix and its high molecular weight (MW) form has anti-inflammatory and anti-fibrotic properties relevant for regenerative medicine. Here, we introduce a new hydrogel based on high MW HA which is cross-linked using the transglutaminase (TG) activity of the activated(More)
New methods for team optimal decision, based on a stochastic agent coordination, are presented, implemented and tested. The methods are extensions of the cross-entropy algorithm (CE), initially dedicated to rare-event simulation. In particular, this paper investigates how the contributions of the agents could be involved in the simulation process. The(More)
