Estradiol acts as a germ cell survival factor in the human testis in vitroV Pentikäinen
Hospital for Children and Adolescents, University of Helsinki, Finland
J Clin Endocrinol Metab 85:2057-67. 2000..The novel findings of the present study together with the previously reported indirect effects of estrogens on male germ cells indicate the importance of estrogens for the normal function of the testis...
TNFalpha down-regulates the Fas ligand and inhibits germ cell apoptosis in the human testisV Pentikäinen
Program for Developmental and Reproductive Biology, Biomedicum Helsinki, and Hospital for Children and Adolescents, University of Helsinki, FIN 00290 Helsinki, Finland
J Clin Endocrinol Metab 86:4480-8. 2001..Thus, in the seminiferous tubules, germ cell-derived TNFalpha may regulate the level of the Fas ligand and thereby control physiological germ cell apoptosis...
Partial oxygen pressure and mitochondrial permeability transition affect germ cell apoptosis in the human testisK Erkkila
Hospital for Children and Adolescents, University of Helsinki, Finland
J Clin Endocrinol Metab 84:4253-9. 1999..The present results imply that to improve germ cell viability in in vitro fertilization techniques, the partial oxygen pressure should be lowered...

Programme for Developmental and Reproductive Biology, Biomedicum Helsinki, Hospital for Children and Adolescents, University of Helsinki, Helsinki, Finland
Mol Hum Reprod 8:109-17. 2002..In conclusion, testicular cell death was effectively regulated by lactate, which may be regarded as a potential compound for optimizing in-vitro methods involving male germ cells for assisted reproduction...
Fas regulates germ cell apoptosis in the human testis in vitroV Pentikäinen
Hospital for Children and Adolescents, University of Helsinki, FIN 00029 Helsinki, Finland
Am J Physiol 276:E310-6. 1999..The present results suggest an important role for the Fas-FasL system in the regulation of germ cell apoptosis in the human testis...
Expression of transcription factor GATA-4 during human testicular development and diseaseI Ketola
Children s Hospital, University of Helsinki, Finland
J Clin Endocrinol Metab 85:3925-31. 2000..GATA-4 protein is abundantly present in Sertoli and Leydig cell tumors, suggesting a relationship to tumorigenesis or tumor progression in somatic cell-derived testicular neoplasms...
