objective(s):mesenchymal stem cells (mscs) derived from wharton’s jelly (wj-mscs) are now much more appealing for cell-based infertility therapy. hence, wj-mscs differentiation toward germ layer cells for cell therapy purposes is currently under intensive study. materials and methods: mscs were isolated from human wharton’s jelly and treated with bmp4, retinoic acid (ra) or co-cultured on human...
In this issue of Endocrinology, there is a rapid communication by Mahato et al. (1) that addresses the issue of estrogen action directly on germinal cells in the testis. The authors transplanted germ cells from the testis of the estrogen receptor a (ERa) knockout mice into the seminiferous tubules of germ cell-depleted wild-type mice. The germ cells carrying the knockout mutation underwent qual...
Up to 3.2% of patients with testicular germ cell tumours represent with late-relapsing disease. Aggressive surgical resection confers the greatest chance of cure in this patient group. We present the case of a late and extensively relapsed nonseminomatous germ cell tumour with thrombus present along the entire length of the inferior vena cava, as well as in the right hepatic vein. Techniques pr...
Testicular cell transplantation has been widely used to investigate the biology of spermatogonial stem cells, production of transgenic animals, and restoration of fertility in rodent models. One critical step in successful transplantation is the preparation of the recipient testes. Busulfan has been widely used, but irradiation has been often suggested as an alternative. There have only been li...
A variety of regimens of high-dose chemotherapy with hematopoietic stem cell support for poor risk germ cell tumors have been established. However, a series of chemotherapy steps carried out prior to the harvest sometimes leads to an insufficient number of peripheral blood stem cells. Here, we report a case of a patient who successfully underwent high-dose chemotherapy for the treatment of poor...
