Protein Enriched Microvesicles and Methods of Making and Using the Same

Protein enriched micro-vesicles and methods of making and using the same are provided. Aspects of the methods include maintaining a cell having a membrane-associated protein comprising a first dimerization domain and a target protein having a second dimerization domain under conditions sufficient to produce a micro-vesicle from the cell, wherein the micro-vesicle includes the target protein. Also provided are cells, reagents and kits that find use in making the micro-vesicles, as well as methods of using the micro-vesicles, e.g., in research and therapeutic applications.

SERUM-FREE INDUCTION METHOD FOR SENSORY NEURON CELL
20230235282 · 2023-07-27 ·

Provided is a human-derived sensory neuron induction culture system. A combination of a small molecule inhibitor LY2157299 and a growth factor is added into a serum-free basal medium. Compared with an induction method involving serum, not only is the efficiency of inducing pluripotent stem cells into sensory neurons greatly improved, but the expression of a variety of ion channel proteins is also significantly improved, thereby achieving successful induction of multiple induced pluripotent stem cells from different sources into sensory neurons.

Process of Using a Fish Plasma Component in a Nutrient Medium for Cell Culture
20230235281 · 2023-07-27 · ·

A process of using a fish plasma component in a nutrient medium for cell culture includes obtaining a fish that is a progeny of domesticated broodstock that are reared under consistent and reproducible conditions. Blood is obtained from the fish, and plasma is separated from the blood. One or more specific components of the plasma are then extracted, and cells are cultured in a nutrient medium using the one or more extracted plasma components, and none of any remainder of the plasma. The plasma and/or the plasma components is/are tested for presence and/or level of endotoxin. Extracting the one or more specific components of the plasma, and/or culturing the cells is only performed if the testing indicates an endotoxin level below a predetermined threshold. The cells cultured using the extracted one or more plasma components are other than fish cells.
