Compositions and methods of cell attachment

Compositions, devices and methods are described for improving adhesion, attachment, and/or differentiation of cells in a microfluidic device or chip. In one embodiment, one or more ECM proteins are covalently coupled to the surface of a microchannel of a microfluidic device. The microfluidic devices can be stored or used immediately for culture and/or support of living cells such as mammalian cells, and/or for simulating a function of a tissue, e.g., a liver tissue, muscle tissue, etc. Extended adhesion and viability with sustained function over time is observed.

METHODS OF TREATING FRAGILE X SYNDROME WITH REELIN
20230054593 · 2023-02-23 ·

Fragile X syndrome (FXS) is the most common inherited form of human intellectual disability. FXS is caused by loss of function of the FMR1 gene which results in significant behavioral deficits in spatial learning and memory tests. FMR1−/− knockout mice share many of the learning deficits and decreased synaptic function encountered in FXS patients. Anecdotal evidence indicates a reduction in the amount of Reelin, a large extracellular signaling protein important for normal hippocampal synaptic plasticity, may play role in the etiology of FXS. Disclosed herein is a rAAV9 Reelin viral vector expressing a REELIN repeat R3+R6 fusion protein that is shown to rescue cognitive deficits in FMR1−/− mice as evaluated in the Hidden Platform Water Maze, Open Field and Fear Conditioning. Reelin gene therapy is therefore potentially a novel therapeutic for the treatment of Fragile X Syndrome.

Programmable liquid, gel and biohybrid compartments and methods of use

Nano- to microscale liquid coacervate particles are provided. The liquid coacervate particles are produced by a process including stimulating a population of liquid droplets containing one or a mixture of components to induce a phase separation point of a first component, and maintaining stimulation at the phase separation point to form a coacervate domain of the first component within each of the droplets to form the liquid coacervate particles. The self-assembled nano, meso, micro and macro liquid coacervate particles and related coated substrates can have utility in drug delivery, bioanalytical systems, controlled cell culture, tissue engineering, biomanufacturing and drug discovery.
