Abstract
FSH acts via testicular Sertoli cells (Sc) bearing FSH receptor (FSH-R) for regulating male fertility. Despite an adult-like FSH milieu in infant boys and monkeys, spermatogenesis is not initiated until the onset of puberty. We used infant and pubertal monkey Sc to reveal the molecular basis underlying developmental differences of FSH-R signaling in them. Unlike pubertal Sc, increasing doses of FSH failed to augment cAMP production by infant Sc. The expression of Gαs subunit and Ric8b, which collectively activate adenylyl cyclase (AC) for augmenting cAMP production and gene transcription, were significantly low in infant Sc. However, forskolin, which acts directly on AC bypassing FSH-R, augmented cAMP production and gene transcription uniformly in both infant and pubertal Sc. FSH-induced Gαs mRNA expression was higher in pubertal Sc. However, Gαi-2 expression was down-regulated by FSH in pubertal Sc, unlike infant Sc. FSH failed, but forskolin or 8-Bromoadenosine 3',5'-cyclic monophosphate treatment to infant Sc significantly augmented the expression of transferrin, androgen binding protein, inhibin-β-B, stem cell factor, and glial-derived neurotropic factor, which are usually up-regulated by FSH in pubertal Sc during spermatogenic onset. This suggested that lack of FSH mediated down-regulation of Gαi-2 expression and limited expression of Gαs subunit as well as Ric8b may underlie limited FSH responsiveness of Sc during infancy. This study also divulged that intracellular signaling events downstream of FSH-R are in place and can be activated exogenously in infant Sc. Additionally, this information may help in the proper diagnosis and treatment of infertile individuals having abnormal G protein-coupled FSH-R.

Abstract
Mucopolysaccharidosis type IH (MPS IH) is a rare autosomal recessive lysosomal storage disorder. Haematopoietic stem cell transplantation (HSCT) has been proposed for the treatment of MPS IH patients and offers the possibility to grow into their adulthood. Precocious puberty has been described in few MPS patients. We report, to the best of our knowledge and for the first time, the initiation of the first waves of spermatogenesis fortuitously observed in seminiferous tubules of a pre-pubertal 19-month-old boy, affected by MPS IH and who did not present any clinical signs of precocious puberty. This patient benefited from testicular tissue cryopreservation before HSCT. Seminiferous tubule size, germ cell differentiation and Sertoli cell expression of androgen receptor and anti-müllerian hormone corresponded to the pattern observed in a pubertal boy. The Hurler syndrome may be responsible for the precocious initiation of spermatogenesis. A specific follow-up during childhood may be useful to confirm if such abnormal testis development is common in young boys with MPS IH and if it may lead to precocious onset of puberty in survivors despite HSCT. Furthermore, we have observed that Sertoli cell maturation (up-regulation of AR expression, down-regulation of AMH expression) occurred before the clinical signs of puberty and before the increase of testosterone plasmatic level.

Abstract
The morphogenesis of tissues and organs requires dynamic changes in cells and in extracellular matrix components. It is known that various extracellular matrix molecules are of fundamental importance for gonad differentiation and growth. In the adult testis, the extracellular matrix represents an important component of the interstitium, participating in the transport of biologically active substances needed for the communication between different cellular components, as well as for the regulation of spermatogenesis and hormone production. The present study was designed in order to identify the proteoglycans biglycan, decorin and perlecan, as well as the glycosaminoglycan hyaluronan, during testis development in mouse embryos. Our data profile the chronology of testis differentiation, as well as the distribution of these extracellular matrix components during testis development in mice. We show that these extracellular matrix molecules are present early in the development of the gonads, suggesting that they play a role in gonad development. In addition, we found no decorin in the testicular cords. Furthermore, of the proteoglycans analysed, only biglycan was seen surrounding immature Sertoli cells and Leydig cell precursors in the testicular cords. This indicates that specific sets of extracellular matrix molecules are required in the various compartments of the developing gonad.

Abstract
Proteoglycans have been identified within the extracellular matrices (ECM) of bone and are known to play a role in ECM assembly, mineralization, and bone formation. Bone morphogenetic protein-2 (BMP-2) specifically converts the differentiation pathway of C2C12 myoblasts into that of osteoblast lineage cells. Microarray analyses of the mouse myoblast cell line C2C12 and its differentiation into osteoblastic cells in response to BMP-2 have suggested the up-regulation of several proteoglycan species, although there is a lack of biochemical evidence for this response. In this study we have biochemically analyzed and characterized the proteoglycan populations that are induced in C2C12 cells upon osteoblastic differentiation produced by BMP-2. An important and specific increase in the synthesis of secreted decorin was observed in BMP-2-treated cells, as compared to untreated myoblasts and myoblasts induced to differentiate into myotubes. Decorin was seen to contain larger glycosaminoglycan (GAG) chains in induced than in non-induced cells. BMP-2 also produced an augment in the synthesis of different heparan sulfate proteoglycans such syndecan-2, - 3, glypican, and perlecan in detergent-soluble and non-soluble cellular fractions. We also examined whether the evident changes induced by BMP-2 in secreted decorin could have a functional role. BMP-2 signaling dependent as well as induction of alkaline phosphatase (ALP) activity was diminished in decorin null myoblasts compared to wild type myoblats although cell surface level of BPM-2 receptors was unchanged. These results are the first biochemical evidence and analysis for the effect of BMP-2 on the synthesis of proteoglycan during osteogenic conversion of myoblasts and suggest a role for decorin in cell response to BMP-2.

Abstract
CONTEXT Human papillomavirus (HPV) plays a major role in the etiology of many malignancies of diverse localization, such as uterine cervical carcinoma and its precursors. Human papillomavirus sequences have been detected throughout the male lower genitourinary tract, but the role of men as transmitters remains unclear. OBJECTIVE To investigate the relationship between azoospermia and the presence of HPV DNA in testicular cells. DESIGN One hundred eighty-five patients with azoospermia undergoing testicular biopsy were studied. Histologic study was done on formalin-fixed, paraffin-embedded samples from testicular biopsies, stained with hematoxylin-eosin. Molecular study to detect HPV sequences was performed on genomic DNA isolated from paraffin sections by standard protocols. Seven cases containing HPV sequences were studied after microdissection with PALM microlaser technology in order to determine the presence of HPV DNA sequences in different cells, as well as from seminal tubules or stromal (Leydig) cells. RESULTS Human papillomavirus DNA sequences were detected in testicular biopsies of 12 patients (6.48%). Human papillomavirus type 16 was the most common genotype encountered. Among the 92 patients who underwent bilateral testicular biopsy, HPV sequences were detected in 9 patients (9.78%), all of whom showed only unilateral testicular affection, more often in the left testicle (ratio, 2: 1). After microdissection, HPV DNA sequences were seen in Leydig and Sertoli cells; the presence of HPV in germinal cells could not be ruled out. CONCLUSIONS Leydig cells, Sertoli cells, and probably germinal cells (cases 2, 3, and 4) harbored HPV DNA sequences. Such findings have not been previously described in testicular tissue.

Abstract
There is a renewed enthusiasm for the potential of cellular transplantation as a therapy for numerous clinical disorders. The revived interest is largely due to the unprecedented success of the "Edmonton protocol," which produced a 100% cure rate for type I diabetics following the transplantation of human islet allografts together with a modified immunosuppressive regimen. While these data provide a clear and unequivocal demonstration that transplantation is a viable treatment strategy, the shortage of suitable donor tissue together with the debilitating consequences of lifelong immunosuppression necessitate a concerted effort to develop novel means to enable transplantation on a widespread basis. This review outlines the use of Sertoli cells to provide local immunoprotection to cografted discordant cells, including those from xenogeneic sources. Sertoli cells are normally found in the testes where one of their functions is to provide local immunologic protection to developing germ cells. Isolated Sertoli cells 1) engraft and self-protect when transplanted into allogeneic and xenogeneic environments, 2) protect cografted allogeneic and xenogeneic cells from immune destruction, 3) protect islet grafts to reverse diabetes in animal models, 4) enable survival and function of cografted foreign dopaminergic neurons in rodent models of Parkinson's disease (PD), and 5) promote regeneration of damaged striatal dopaminergic circuitry in those same PD models. These benefits are discussed in the context of several potential underlying biological mechanisms. While the majority of work to date has focused on Sertoli cells to facilitate transplantation for diabetes and PD, the generalized ability of these unique cells to potently suppress the local immune environment opens additional clinical possibilities.

Abstract
Heparan sulfate (HS) present on the surface of hemopoietic stromal cells has important roles in the control of adhesion and growth of hemopoietic stem and progenitor cells. Recent studies have characterized several different heparan sulfate proteoglycans (HSPGs) from both human and murine bone marrow stromal cells. In the present study, we have compared the molecular structure of HS, metabolically labeled with [(35)S]-sulfate produced by two distinct preparations of murine hemopoietic stromal cell lines. These comprised a bone marrow-derived cell line S17 and a fetal liver-derived cell line AFT024. [(35)S]-HS was examined in the cell layers and in the culture medium. We identified and measured the relative proportions of the various glycosaminoglycans (GAGs) in the two stromal cell lines. Chondroitin sulfate (CS) was preponderantly secreted by the stromal cell lines, while HS was relatively more abundant in the cell-associated fractions. The two types of stromal cells differ in their HS composition, mainly due to different patterns of N- and O-sulfation. The two stromal cell lines expressed mRNA for different HSPGs. Data from reverse transcription PCR revealed that the two stromal cell lines expressed mRNA for glypican and syndecan4. Only AFT024 cell line expressed mRNA for betaglycan. There was no evidence for expression of mRNA for both syndecan1 and syndecan2. [(35)S]-sulfated macromolecules could be released from the cell surface of both stromal cell lines by phosphatidylinositol phospholipase C (PI-PLC), which is consistent with the expression of glypican detected by PCR experiments.

Abstract
In seminiferous tubules, Sertoli cells provide structural and nutritional support for the developing germinal cells. Cell- to-cell signaling and cell adhesion require proteoglycans expressed at the cell membrane. A preliminary biochemical and structural approach indicated that cell surface proteoglycans are mostly heparan sulfate proteoglycans (HSPG). Glypican-1, syndecans-1 and -4 were identified using a molecular approach. Their differential regulation was demonstrated in immature rat Sertoli cells. Follicle-stimulating hormone (FSH) is the main regulator of Sertoli cell function. Signal transduction triggered by FSH involves both an increased intracellular cAMP synthesis and a calcium influx. This study demonstrates that FSH, through its second messengers (increase in intracellular cAMP and intracellular calcium), downregulated the glypican-1 mRNA expression in Sertoli cells from 20-day-old rats. On the other hand, syndecan-1 mRNA expression is not modulated by FSH as it would result from the antagonistic effects of increased intracellular cAMP and intracellular calcium levels. Finally, syndecan-4 mRNA expression is not regulated by this pathway. The present study was extended during Sertoli cell development. Indeed, Sertoli cells undergo extensive changes during the postnatal period both in structure and function. These important transformations are critical for the establishment of spermatogenesis and development of the adult pattern of testicular function. Our data indicated that the regulation of HSPG mRNA expression is HSPG-specific and depends on the Sertoli cell developmental stage.

Abstract
Our previous studies indicated that cell surface proteoglycans were mostly heparan sulfate ones (HSPG) in 20 day-old Sertoli cells [Biochim. Biophys. Acta 1510 (2001) 474]. Among these HSPG, glypican-1, syndecans-1 and -4 mRNAs were expressed and differentially regulated. Glypican-1 and syndecan-1 mRNA expression was up-regulated under PKC activation in contrast to syndecan-4 mRNA expression which was not affected [Biochim. Biophys. Acta 1474 (2000) 31]. Rat Sertoli cells undergo extensive changes during the postnatal period both in structure and function, as the hematotesticular barrier establishment occurs at around 20 day-old. The testicular PKCalpha expression in developing Sertoli cells results in (i) a soluble (inactive) form which is maximal at the age of 1 day and declines gradually thereafter and (ii) a particulate (active) form which is low at birth, increases six-fold on days 8-11 of age and declines thereafter. The present study focused on the glypican-1, syndecan-1 and syndecan-4 mRNA expression and regulation under PKC activation by the phorbol myristate acetate (PMA) in 10-30 day-old Sertoli cells. Our data indicated that the regulation of their expression specifically depends on the nature of HSPG and Sertoli cell developmental stage and evidenced a specific PKC regulation of HSPG mRNA expression.

Abstract
Basic fibroblast growth factor (bFGF) regulates diversified biological functions in rat Sertoli cells. This report demonstrates that bFGF inhibits steroidogenesis in developing rat Sertoli cells. Follicle stimulating hormone (FSH)-stimulated estradiol production was reduced by bFGF. Moreover, the amount of cytochrome P450 aromatase, responsible for the irreversible transformation of androgens into estrogens, is decreased by bFGF at the transcriptional level. The bFGF inhibitory effect was also observed in the presence of dibutyryl-cAMP, cholera toxin or RO-20-1724, all inducing high levels of cAMP, the second messenger of FSH. Heparan sulfate proteoglycans (HSPGs) were shown to be required as cofactors for bFGF signaling. Indeed, sodium chlorate, described to drastically decrease proteoglycan sulfation, abolishes the bFGF downregulation of FSH-stimulated estradiol synthesis previously observed. Glypican-1, syndecan-1 and -4, potential bFGF coreceptors, are mainly regulated at the transcriptional level. This report shows that the bFGF regulation of their expression specifically depends on the nature of HSPG and of the Sertoli cell developmental stage. In conclusion, HSPG are partners and the target of bFGF in rat Sertoli cells.
