C57BL/6J male mice (2–5 months of age) were housed individually on a 12 hr/12 hr light/dark schedule with lights on at 7 A.M. (ZT0) and handled for 6 days. Mice were sleep-deprived (SD) in their home cages for 5 hours by gentle handling beginning at ZT5 or left undisturbed (non-sleep-deprived mice, NSD). For contextual fear conditioning experiments, animals were placed in a novel chamber for 3 minutes, and received a 2-second, 1.5 mA footshock after 2.5 minutes. Half of the mice were deprived of sleep for 5 hours post-training. Mice received intra-peritoneal injections of rolipram (ROL; 1 mg/kg) or vehicle (2% DMSO in 0.9% saline) immediately and 2.5 hours post-training. Testing of contextual memory was performed 24 hours after training in the trained context and 48 hours after training in a novel chamber.
Electrophysiological recordings were carried out as previously reported28 (link). 1-train LTP was induced by a single 100 Hz, 1-second duration train of stimuli. 4-train LTP consisted of 4 trains applied with a 5-minute inter-train interval; for massed 4-train LTP a 5-second inter-train interval was used. Theta-burst stimulation (TBS) consisted of 40-ms duration, 100 Hz bursts delivered at 5 Hz for 3 seconds (15 bursts of 4 pulses per burst, for a total of 60 pulses). Chemical LTP was induced by treatment of slices for 15 minutes with 5µM forskolin (FSK) in 0.1% ethanol, or a combination of 50µM forskolin and 30µM 3-isobutyl-1-methylxanthine (IBMX, in water). Rolipram (0.1µM in 0.1% DMSO) was applied for 60 minutes, beginning 30 minutes before tetanization.
cAMP assays on CA1 regions of hippocampal slices 10 minutes after treatment for 15 minutes with forskolin (50µM), forskolin + IBMX (30µM), or vehicle (0.1% EtOH) were performed by radioimmunoassay according to kit instructions. cAMP-specific PDE activity assays29 (link) and Western blots for PDE4A530 (link) were performed as previously described.

We differentiated hiPSCs into ECs according to the protocol previously described by Patsch et al. (36 (link)) and then adapted for differentiation in 3D culture. In brief, hiPSCs were dissociated from 10-cm plates using ReLeSR (StemCell Technologies) according to the manufacturer’s instructions. Cells were seeded into 125-ml Erlenmeyer flasks at 200,000 cells/ml in 20 ml of StemScale media (Thermo Fisher Scientific) containing 10 μM Y-27632 and then placed on a plate shaker rotating at 70 rpm. Media were changed to fresh StemScale media the next day to remove the ROCK inhibitor. EC differentiation began 4 days after seeding, when spheroids reached approximately 300 μm in diameter. On day 0 of differentiation, media were changed to N2B27 medium containing 7 μM CHIR99021 and BMP-4 (25 μg/ml) and incubated for 3 days without media change. On day 3 of differentiation, media were changed to StemPro-34 containing GlutaMAX (Thermo Fisher Scientific) with 2 μM forskolin (Selleck Chemicals) and VEGF (200 ng/ml) (PeproTech). This same media composition with StemPro-34, forskolin, and VEGF was changed fresh daily for 3 days through day 5 of differentiation. On day 6 of differentiation, spheroids were dissociated using 0.5% trypsin-EDTA diluted 1:3 in phosphate-buffered saline (PBS) for ~5 min. CD144+ ECs were sorted using magnetic microbeads using magnetic-activated cell sorting columns (Miltenyi Biotec) according to the manufacturer’s instructions. Sorted CD144+ ECs were replated on Geltrex-coated 10-cm plates and allowed to proliferate for 3 to 7 days in StemPro-34 containing GlutaMAX and VEGF (50 ng/ml) and then redissociated with trypsin-EDTA and replated again onto Geltrex-coated plates for assay.

Kisspeptin-10 (rat) and kisspeptin antagonist (p234) were purchased from Tocris Bioscience (Abingdon, Oxon, UK). Kisspeptin-10 corresponds to the C-terminal region of the translated kisspeptin 54 peptide (residues 112–121), and its sequence is identical in rat and bovine. Kisspeptin-10 and p234 (antagonist) were dissolved in water and 20% (w/v) acetonitrile in water, respectively, to give a stock concentration of 10–3 M. These were further diluted in sterile medium to give final concentrations of 10–6, 10–7, 10–8, 10–9 and 10–10 M. In each culture model, the effects of kisspeptin-10 and kisspeptin antagonist on steroid production and viable cell number were evaluated under both basal and gonadotrophin or forskolin (FSK)-stimulated conditions as explained below. Highly purified ovine FSH (oFSH 19SIAPP) and LH (oLH-S-16) were provided by the NHPP (Torrance, CA, USA). In NLTC cultures, LH was used at a final concentration of 150 pg/mL, shown previously to elicit maximal A4 secretion (Glister et al. 2005 (link)); A4 and P4 secretion were evaluated. In NLGC cultures, FSH was used at a final concentration (0.3 ng/mL) shown previously to elicit optimal E2 secretion (Glister et al. 2001 (link), 2004 (link)); E2 and P4 secretion were evaluated. As LGC and LTC are largely unresponsive to gonadotrophin stimulation in this serum-supplemented culture model (Kayani et al. 2009 (link)), the adenylate cyclase activator, forskolin (FSK; 10 μM), was used as an alternative secretagogue; only P4 secretion was evaluated for these cells since A4 and E2 secretion are both extremely low.

FRC cell lines were established from peripheral LNs by long-term culturing as described previously74 (link) with minor modifications. In brief, LNs from 8-week-old C57BL/6 N mice were dissected and disrupted using two 25 G needles before enzymatic digestion with DMEM medium containing 3.5 mg/ml Collagenase D and 40 μg/ml DNase I at 37 °C for 30 min with agitation75 . The mixture was then filtered through a 70 μm cell strainer and centrifuged at 300 g for 5 min at 4 °C. The cell pellet was resuspended and cultured in DMEM medium (supplemented with 10% FBS and 1% Penicillin/Streptomycin) (5% CO2, 37 °C). After 24 h, non-adherent cells were removed, and fresh medium was added to continue culturing until cells reached confluence. Adherent-stromal cells were then trypsinized, and triple-stained with antibodies to identify FRCs: Cd45 Pacific blue (1:100), Cd31 PE (1:100) and gp38 APC (1:100). FRCs were sort-purified using a MoFlo Optical Bench Sorter (Beckman Coulter) to achieve a purity of ≥95%. The sorted cells were immediately cultured in DMEM medium for expansion, and then seeded into 60 mm dishes in a density of 3 × 105 per well to grow until confluence, followed by starvation for overnight and treatment with 10 μM isoproterenol (Sigma-Aldrich), 5 μM forskolin (Sigma-Aldrich), and 5 μM PKA inhibitor H89 dihydrochloride hydrate (Sigma-Aldrich) for 8 h. Culture media were collected to determine the concentration of IL-33 using a mouse IL-33 immunoassay kit (Immunodiagnostics Limited) or LDH using a CyQUANT LDH Cytotoxicity fluorescent assay kit (Thermo Fisher Scientific).
