21. Paracrine regulation of Sertoli cell proliferation
Sammanfattning : The Sertoli cell is a highly differentiated somatic cell in the seminiferous epithelium of the testis. This cell is of prime importance for both testicular development and spermatogenesis. LÄS MER
22. Regulation of mitochondrial transcription and mtDNA copy number in mammals
Sammanfattning : Functional mitochondria are essential for wellbeing of the cell and the whole organism. Gene expression from the mitochondrial genome (mtDNA) is indispensable for oxidative phosphorylation, but also for the replication of mtDNA, as the replication primers are processed from mtDNA transcripts.

23. Testicular blood flow : methodological and functional studies in the rat
Sammanfattning : Different methods of measuring testicular blood flow in the rat were compared in an attempt to find an accurate method for measuring physiological testicular blood flow. It was found that both the Xenon- 133 clearance technique and the radioactive microsphere technique probably reflect true physiological blood flow in the testis. LÄS MER
24. Novel genes in gonadal development
Sammanfattning : Mammalian sex determination and differentiation can be divided into three major steps. In the first step, which occurs at fertilisation, the genetic sex is established, XX or XY. In the second step, development of the indifferent gonad into either an ovary or a testis takes place. LÄS MER
25. On the role of HMGB1 and IL-1 in tissue barrier defense
Sammanfattning : The specialized epithelial surfaces of the lymphoepithelial tissue in the airways and the seminiferous epithelium of the testis are sites of host-environmental interaction at the same time as they serve important physiological functions in gas exchange and reproduction. The host response of a broken epithelial barrier requires rapid mechanisms to control the microflora and to prevent invasion of pathogens. LÄS MER
