Project description:Cellular dedifferentiation signifies the withdrawal of cells from a specific differentiated state into a M-bM-^@M-^Xstem cellM-bM-^@M-^Y-like undifferentiated state. However, the mechanism of dedifferentiation remains obscure. We showed that mature adipocytes (MA) and follicular granulosa cells (GC), which have distinct functions in vivo, can dedifferentiate during culture in vitro and acquire multipotency. We investigated the dedifferentiation mechanism of MA and GC using global gene expression analyses. Using Affymetrix porcine genome array, we compared global gene expression profiles during dedifferentiation to search for particular biological functions in genes of which expression intensities were increased or decreased by MA and GC dedifferentiation.

We showed that follicular granulosa cells (GC), which have distinct functions in vivo, can dedifferentiate during culture in vitro and acquire multipotency. We investigated the dedifferentiation of GC using global gene expression analyses. Total RNA was isolated from GCs to DFOG cells at 5 time points during dedifferentiation (cultured in 0day, 1day, 2day, 4day and 7day). Each timepoint was performed in triplicate (ie, biological replicates). Using Affymetrix porcine genome array, we performed microarray time course experiments to analyze gene expression profiles during GC dedifferentiation.
