Objective:
To isolate and identify the pituitary adenoma stem-like cells from pituitary adenoma tissue.
Methods:
Total RNA was prepared with 42 cases of pituitary adenoma tissue samples frozen in liquid nitrogen, the expression of Nestin was detected by RT-PCR. Tumor spheres were cultured in serum-free conditions and the immunefluorescence were used to detect the expression of stem cell markers such as Nestin, Sox2.
Results:
The positive rate of Nestin mRNA expression was 88.1% (37/42). The cultured tumor spheres were found positive for Nestin, Sox2 by immunefluorescence detection.
Conclusion:
Stem cell markers are expressed in the pituitary adenoma tissue and the pituitary adenoma stem-like cells can be cultured in serum-free condition.
