TGF-?_1 regulates the expression of multiple genes in prostatic stromal cells in vitro / 中华泌尿外科杂志

ABSTRACT

Objective To study the regulatory effect of TGF ? 1 on the expression of multiple genes in prostatic stromal cells in vitro. Methods The primary culture of prostatic stromal cells (including fibroblasts and smooth muscle cells ) have been established and cultured to 4～6 passages. Then the cells were cultured in the medium with various concentration of TGF ? 1(0.01, 0.10, 1.00 and 10.0 ng/ml)for 48h. By semi quantitative RT PCR method, the androgen receptor(AR), TGF ? 1, bFGF and smoothlin mRNA were measured. Results The expression of AR could be stimulated by low concentration of TGF ? 1 ( P
