However, the mechanisms in this process remain poorly defined. Here we show the effect of transdermal estrogen therapy on expressions of estrogen receptors and T-lymphocyte apoptosis in surgically postmenopausal women. Fifteen surgically menopausal women, 15 naturally menopausal women and 15 young women were chosen in our studies. Peripheral vein blood was collected and serum E2 and FSH levels were assessed using ACCESS. T-lymphocyte apoptosis and the expressions of Fas, FasL and ER subtypes α and β were determined. The serum E2 levels of surgically menopausal woman were significantly higher, and the ＂Improved Kupperman Index＂ and the scores of ＂Menopause Specific Quality of Life Questionnaire＂ in surgically menopausal women were significantly low after ERT. The rates of T-lymphocyte apoptosis and FasL expression in surgically menopausal women were decreased after ERT, but the difference was not significant. The expressions of ERa and ERβ in two menopausal groups were significantly lower than those of the young group. They were both significantly up-regulated after 3 months of ERT. Transdermal ERT could significantly upregulate the serum E2 level, could improve menopausal symptoms and life quality of surgically menopausal women and upregulate ERa and ERβ expressions on T lymphocytes, especially ERp. Thus, the low dose of transdermal ERT may have a protective effect on menopausal women＇s immune function and aging.展开更多

For most of these applications, systemic delivery of the cells is preferred. However, this requires the homing and migration of MSCs to a target tissue. Although MSC hominghas been described, this process does not appear to be highly efficacious because only a few cells reach the target tissue and remain there after systemic administration. This has been ascribed to low expression levels of homing molecules, the loss of expression of such molecules during expansion, and the heterogeneity of MSCs in cultures and MSC culture protocols. To overcome these limitations, different methods to improve the homing capacity of MSCs have been examined. Here, we review the current understanding of MSC homing, with a particular focus on homing to bone marrow. In addition, we summarize the strategies that have been developed to improve this process. A better understanding of MSC biology, MSC migration and homing mechanisms will allow us to prepare MSCs with optimal homing capacities. The efficacy of therapeutic applications is dependent on efficient delivery of the cells and can, therefore, only benefit from better insights into the homing mechanisms.展开更多
