Abstract: The present disclosure relates to compositions and methods of modulating B lymphocyte activity, and organ protection after acute injury. In particular, PEG-Pirfenidone has increased half-life, improved bioavailability and is equipotent in modulating B cell activity and is particularly useful as protective agents from acute organ damage and disease caused by dysregulation of B cell activity.

Abstract: The present invention provides methods and compositions for increasing the hematopoietic potential of a population of hematopoietic progenitor cells, vascular cells, and or hemogenic endothelium, by exposing the cells to at least one external biomechanical stimulus. More specifically, the application of shear stress to hematopoietic progenitor cells or endothelial cells stimulates hematopoiesis, with or without concurrent application of other extrinsic modulators of hematopoiesis.

Abstract: We describe a system for the division or partition of a volume of fluid into droplets of assigned size and subsequent recollection of the drops.

Abstract: A method and apparatus for producing a jet or droplet of liquid. An injector device may include a reservoir in fluid communication with a nozzle, and a pressure gradient may be produced in the reservoir (e.g., by a piezoelectric element in an initial direction that is transverse to the emission direction of the jet or droplet) to produce a jet of liquid from the nozzle. The jet or droplet of liquid may be introduced through a cell membrane and into the cell interior in such a way that damage to the cell membrane that would cause cell death is avoided. An electrode may be formed adjacent a fluid channel by conducting a liquid material, such as solder, from a reservoir and into an electrode portion of an electrode channel to a location adjacent the fluid channel. A passageway between the electrode channel and the fluid channel may prevent flow of the liquid electrode material into the fluid channel during electrode formation.

Abstract: Here we describe an integrated microfluidic chip for delivery of fluids inside or in proximity of individual cells or for measurement of physical quantities. In this device, a cell suspension is pumped through a microchannel in which cells are lined up, pushed on a static microneedle or micropipette, and then collected in a reservoir. The channels are microfabricated. Valves can be embedded in the system to allow fluid flow control thus enhancing the efficiency of the system and reducing malfunctioning due to clogging or any other unexpected issues.
