骨髓干细胞(BMSCs)具有分化为多种组织的成熟细胞类型的能力。因此,它们代表了退行性疾病器官特异性细胞替代疗法的替代来源。在这项研究中,我们证明了雌性大鼠BMSCs可以分化为类固醇生成细胞,具有从头合成E2 -17β(E2)的能力,在高糖培养条件下,有或没有维甲酸(RA)。体外培养的骨髓间充质干细胞可表达雌激素合成酶P450 arom的mRNA和蛋白。此外,放射免疫分析显示,在本培养系统中培养的骨髓基质细胞产生和分泌大量的睾酮,雄烯二酮,和E2。此外,RA促进E2分泌,但不影响雄激素水平。这些结果表明,骨髓基质细胞可以合成和释放E2,并可能有助于自体移植治疗雌激素缺乏症。
Bone marrow stem cells (BMSCs) have the capacity to differentiate into mature cell types of multiple tissues. Thus, they represent an alternative source for organ-specific cell replacement therapy in degenerative diseases. In this study, we demonstrated that female rat BMSCs could differentiate into steroidogenic cells with the capacity for de novo synthesis of Estradiol-17β (E2) under high glucose culture conditions with or without retinoic acid (RA). The cultured BMSCs could express the mRNA and protein for P450arom, the enzyme responsible for estrogen biosynthesis. Moreover, radioimmunoassay revealed that BMSCs cultured in the present culture system produced and secreted significant amounts of testosterone, androstenedione, and E2. In addition, RA promoted E2 secretion but did not affect the levels of androgen. These results indicate that BMSCs can synthesize and release E2 and may contribute to autologous transplantation therapy for estrogen deficiency.
