| Sample type |
RNA |
| |
|
| Source name |
granulosa cells of small follicles (< or = 5 mm)
|
| Organism |
Bos taurus |
| Characteristics |
granulosa cells of small follicles (< or = 5 mm) from follicular stage ovaries of young nonpregnant cycling heifers
granulosa cells were isolated by dissection (i.e. scraped and flushed) from the fresh tissue as previously described (Skinner and Osteen, 1988). Cell preparations have been characterized cytochemically to be greater that 98% pure and contain less than 1% contamination with endothelial cells.
|
| Treatment protocol |
Bovine ovaries were obtained from of young nonpregnant cycling heifers less then 10 min after death. Ovaries were delivered fresh on ice to laboratory. Only follicular stage ovaries were used as assessed by morphological criteria that include the absence of a corpus luteum and the presence of developing large antral follicles.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Cells from 20-40 follicles of the same size were pooled to make each RNA sample. RNA was extracted using the Trizol reagent according to manufacturers instructions (Sigma, St. Louis, MO).

| Description |
RNA from theca cell of small follicles
|
| Data processing |
Auto-scale ON (1-1000). Scaling = all probe sets, Target Signal 125. The microarray chip image data were converted to numerical data with GeneChip Operating Software (Affymetrix) using MAS-5 preprocessing algorithm.
The absolute analysis from MAS was imported into GeneSpring 7.3 software (Silicon Genetics, Redwood City, CA). The developing follicle data were normalized within GeneSpring using the default/recommended normalization methods. These include setting of signal values below 0.01-0.01, total chip normalization to the 50th percentile, and normalization of each gene to the median.
