Assessment of human embryo development using morphological criteria in an era of time-lapse, algorithms and ‘OMICS’: is looking good still important? This is obtained by FSH injections after down-regulation by GnRH agonists or antagonists (Hughes et al., 1992; Liu et al., 1992; Minaretzis et al., 1995). Mean values of the differences (±SEM) are presented. Also, gene expression leading to collagen IV and laminin production has been identified in bovine corpus luteum (Zhao and Luck, 1995). As a second control, we used luteinized GCs from IVF patients (n = 6; mean age 34 ± 2.3) and cultured them for 72 h before stimulation. (, O'Sullivan, M.J.B., Stamouli, A., Thomas, E.J. Images shown in Figure 3 are `virtual confocal slices' where scanning parameters have been standardized, allowing comparison between images for each ECM component examined. There is potential for using human cultured GC derived from follicular aspirates as a model system for looking at deposition of ECM by GC in the corpus luteum of the primate. Similarly, by stimulating thecal cells to produce androgens, LH augments growth and development of granulosa cells through the paracrine actions of both estrogens and androgens whose receptors are abundantly expressed in these cells. Smooth muscle differentiation in ovarian granulosa-cell tumours: a new case report. In addition, the granulosa lutein cells also retain the capacity to synthesize estrogens from androgen precursors produced by theca lutein cells. (, Oxford University Press is a department of the University of Oxford. In differentiated GCs, FSH also induces cytochrome P-450scc (CYP11A) that catalyses the rate-limiting conversion of cholesterol to pregnenolone, promoting the production of increasing amounts of progesterone (Richards et al., 1998). Briefly, cells were collected by centrifugation and then centrifuged over 45% Percoll (Pharmacia, St Albans, UK) to remove red blood cells. Yu Sun, Nelly Auersperg, in The Ovary (Third Edition), 2019. Richardson, Luteinized human granulosa cells are associated with endogenous basement membrane-like components in culture, Molecular Human Reproduction, Volume 6, Issue 4, April 2000, Pages 324–330, https://doi.org/10.1093/molehr/6.4.324. Fourty nanograms of mRNA, 1 µl of random hexamers (50 ng), 1 µl of dNTP-mix (10 mmol/l) and diethyl pyrocarbonate (DEPC)-treated water up to 10 µl were mixed and incubated at 65°C for 5 min and then immediately placed on ice. The Genetics Analysis of Molecular Pathogenesis for Alzheimer's Disease. Nrf1 is paved as a new strategic avenue to prevent and treat cancer, neurodegenerative and other diseases. Mean values (±SEM) are presented. LH stimulates thecal cells to produce androstenedione. (, Asakai, R., Tamura, K., Eishi, Y. et al. Cooperative interaction of both cell types is required for physiologically relevant rates of estradiol production in the follicular phase. the antibody reacts with both the human and mouse β1-laminin). Human luteinized granulosa cells secrete apoB100-containing lipoproteins Thomas Gautier , *, 1 Steffi Becker , †, 1 Véronique Drouineaud , § Franck Ménétrier , ** Paul Sagot , § Jerzy-Roch Nofer , †† Sören von Otte , † Laurent Lagrost , * David Masson , * and Uwe J. F. Tietge 2, * §§ Gene expression of FSH receptor (FSHR) and LH receptor (LHR) in granulosa cells (GCs) obtained by in vitro maturation (IVM) of oocytes. Bars represent SEM between quadruplicates. The expression of the FSHR in non-luteinized GCs did not change significantly with the different treatments. Aromatase activity in granulosa cells is estimated to be at least 700 times greater in large preovulatory follicles than in the associated theca cells.
