Description
There is a lack of systematic investigations of large-scale transcriptome patterns associated with normal breast development. Herein, we profiled whole-transcriptome (by microarrays) of normal mammary glands in female Sprague-Dawley rats, an animal model widely used in breast cancer research, across six distinctive developmental stages pre-pubertal, peri-pubertal, pubertal, lactation, and adult parous and age-matched nulliparous.
