69 results about "Intracellular transport" patented technology

Intracellular transport is the movement of vesicles and substances within the cell. Eukaryotic cells transport packets of components (membrane‐bound vesicles and organelles, protein rafts, mRNA, chromosomes) to particular intracellular locations by attaching them to molecular motors that haul them along microtubules and actin filaments. This method of transport is often confused with intercellular transport, which deals solely with the movement of cargo between cells not the net movement within a cell. Since intracellular transport heavily relies on microtubules for movement, the components of the cytoskeleton play a vital role in trafficking vesicles between organelles and the plasma membrane.

Systems and methods for cell preservation

The present invention generally relates to devices and methods for the preservation of cells using drying, freezing, and other related techniques. In one set of embodiments, the invention allows for the preservation of cells in a dried state. In another set of embodiments, the invention allows for the preservation of cells within a glass or other non-viscous, non-frozen media. In some embodiments, the invention allows for the preservation of cells at temperatures below the freezing point of water, and in some cases at cryogenic temperatures, without inducing ice formation. The cells, in certain embodiments, may be preserved in the presence of intracellular and / or extracellular carbohydrates (which may be the same or different), for example, trehalose and sucrose. Carbohydrates may be transported intracellularly by any suitable technique, for example, using microinjection, or through non-microinjected methods such as through pore-forming proteins, electroporation, heat shock, etc. In certain instances, the glass transition temperature of the cells may be raised, e.g., by transporting a carbohydrate intracellularly. In some cases, the cells may be dried and / or stored, for example, in a substantially moisture-saturated environment or a desiccating environment. The cells may also be stored in a vacuum or a partial vacuum. The cells may be protected from oxygen, moisture, and / or light during storage. In certain cases, an inhibitor, such as a cell death inhibitor, a protease inhibitor, an apoptosis inhibitor, and / or an oxidative stress inhibitor may be used during preservation of the cells. The cells may be stored for any length of time, then recovered to a viable state, e.g., through rehydration, for further use.

Fluorescent cytotoxic compounds specific for the cellular polyamine transport system

Cyano-substituted anthracene containing polyamines were synthesized and shown to be efficient polyamine transporter ligands. Moreover, these compounds (3 and 4) had improved fluorescence properties over previously known anthryl-polyamine conjugates, which facilitated their intracellular trafficking by confocal microscopy and fluorescence methods. These cytotoxic fluorescent agents may find use as molecular probes which traffic into cells via the polyamine transport system and may also be viable anticancer drugs which are readily quantified in human tissues due to their excellent fluorescence properties: (excitation: λ405 nm) and emission (420 nm) occurs in the visible light range. The ability to excite and emit in the visible range provides an advantage to these probes as these wavelengths are considered non-toxic to human cells (versus ultraviolet mediated excitations, λ<400 nm) and visible light lasers are less costly to purchase and operate than UV laser sources.
