The lining epithelium of the stomach includes multipotent stem cells which undergo proliferation and migration-associated differentiation. These cells give rise to multiple cell lineages that produce mucus, acid, pepsinogen and various hormones/peptides. A 3D culture for stem cells would facilitate identification of the factors that control proliferation and/or differentiation programs. Here, we report on the use of disk-like ImmobaSil HD silicone-rubber matrix based microcarriers that are permeable to oxygen and reduce the creation of toxic environment within the center of the microcarrierd for culturing the mouse gastric stem (mGS) cells. We define several parameters that affect the initial cell attachment such as size of cell inoculum, serum concentration, mode and speed of agitation. We show that although such a microcarrier allows for attachment and growth of gastric stem cells, it does not lend itself and does not support the functional differentiation of such cells.

UI MeSH Term Description Entries
D002454 Cell Differentiation Progressive restriction of the developmental potential and increasing specialization of function that leads to the formation of specialized cells, tissues, and organs. Differentiation, Cell,Cell Differentiations,Differentiations, Cell
D003470 Culture Media Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN. Media, Culture
D000818 Animals Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.
