    摘要: A preservation method for biological material having cell membranes includes microinjecting the cells with sugar; preparing the cells for storage; storing the biological material; and recovering the stored biological material from storage. Carbohydrate sugars such as trehalose, sucrose, fructose, dextran, and raffinose, may be used as bio-protective agents.

    摘要: The present invention generally relates to methods and compositions to determine viability of an organ for transplantation and other medical purposes. One aspect of the invention relates to a method for assessing the viability of an organ by measuring the energy parameters to determine the energy level of the organ by determining the stored cellular energy (e.g., ATP levels), and/or energy consumption over a particular time period of viability. The energy parameters can be compared to reference energy parameters as a highly accurate and reliable prediction of viable cell yield, and organ viability. Another aspect of the invention relates methods to preserve or extend the time period of viability of an organ any combination of (i) preservation perfusion of the organ to prevent ischemic damage, (ii) chemical metabolic suppression of the organ e.g., using metabolic suppressants, (iii) metabolic suppression by physical or environmental conditions, e.g., sub-zero non-freezing storage.

    摘要: Microfluidic devices and methods for the encapsulation of particles within liquid droplets are disclosed. The new methods and devices form 1-100 picoliter-size monodisperse droplets containing the particles, such as single cells, encapsulated in individual liquid droplets. The particles can be encapsulated in droplets of a fluid by passing a fluid containing the particles through a high aspect-ratio microchannel to order the particles in the fluid, followed by forming the fluid into droplets. The resulting fraction of the liquid droplets with a single particle (e.g., a cell) is higher than the corresponding fraction of single-particle liquid droplets predicted by Poisson statistics.

    摘要: The invention relates to new flow-through cell culturing devices that include plates arranged in parallel and spaced to control the flow patterns and velocity of liquid medium flowing between the plates. The devices can also include gas-permeable, liquid impermeable membranes arranged between the plates. The devices can be used to culture cells, such as hepatocytes, at high levels of mass transport of nutrients, oxygen, and waste products, yet low levels of shear stress for extended periods of time and with high levels of cell function, e.g., in organ assist systems. The invention also includes new culturing plates for use in the devices, and methods of manufacturing these plates.
