Twenty two hours after stroke, the mice were anesthetized with isoflurane. An incision was made through the skin to the medial aspect of the left tibia. The periosteum was removed and the surgeon drilled a 0.5 ×0.5mm burr hole extending into the medullary cavity. A 261/2 gauge hypodermic needle was inserted into the medullary cavity and connected to a heparinized syringe. Bone marrow was aspirated while rotating and moving the needle back and forth. The medullary cavity was flushed with saline and the content aspirated. The burr hole was sealed with bone wax and the skin was closed. In the saline control group, only the needle was inserted into the medullary cavity but no content was aspirated.
The cells from the bone marrow aspirate were triturated, centrifuged, and washed in PBS + 0.5% bovine serum albumin (BSA). Cells were then suspended in Media 199 (Sigma, USA) and counted using a hemocytometer and coulter counter. The cell suspension was added on top of 5 mL Ficoll-Paque PLUS (GE, USA) in a 15mL conical vial and then centrifuged. The MNCs were collected, washed with PBS+0.5% BSA, and then counted. Cells were then suspended in sterile, iced PBS at the desired concentration before cell separation.

Check if the same lab product or an alternative is used in the 5 most similar protocols
Control cell lines were used as positive controls (MCF-7, SH-SY5Y) and to test differential response to treatment (SVOG-3e). MCF-7, an estrogen- and progesterone-receptor-positive human breast cancer cell line, was used as positive control for the anti-hormonal therapies [49 (link)]. Additionally, SH-SY5Y, a human neuroblastoma cell line, was used as positive control for chemotherapeutic agents [50 (link)]. KGN, a human AGCT cell line derived from a 63-year-old patient heterozygous for FOXL2 c.402C > G, was used as an additional AGCT cell line to evaluate potential AGCT response [51 (link)]. Finally, the immortalized human granulosa cell line SVOG-3e [52 (link)] was used to assess selective drug response in AGCT versus healthy granulosa cells. SH-SY5Y and MCF-7 were cultured in DMEM/F12 (Thermo Fischer Scientific) + 10% FBS and 1% Pen/Strep and RPMI 1640 (Thermo Fischer Scientific, Waltham, MA, USA) + 10% FBS and 1% Pen/Strep, respectively. KGN was cultured in conditions identical to AGCT-patient-derived cell lines. SVOG-3e was cultured in a 1:1 ratio of Media 199 and Media 105 (Sigma-Aldrich, St. Louis, MO, USA) with 5% FBS and 1% Pen/Strep.

Culture of ovarian cancer cell lines OV2295, TOV2295, and OV2295R cells were cultured in a 1:1 mix of Media 199 (Sigma Aldrich) and MCDB 105 (Sigma Aldrich) supplemented with 10% FBS in a humidified environment at 37C. For single-cell RNA sequencing, all cells used in this study were sorted on a BD Influx into 384 well plates using index-sorting and single-cell purity mode directly into lysis buffer(6,67% Polyethylene Glycol, 0.1% Triton X-100, RNAse Inhibitor (Takara), dNTPs (0.67 mM/each), and Oligo-dT (0.67uM)). Sorted plates were stored at −80 °C and thawed immediately prior to library generation. The cell line originates from ref. 27 (link).

Check if the same lab product or an alternative is used in the 5 most similar protocols
Ovaries were collected from the slaughterhouse immediately after slaughter and transported in a thermos. They were washed with saline solution at 38 °C upon arrival at the laboratory. A vacuum pump and an 18-gauge needle were used to aspirate cumulus-oocyte complexes (COCs). A follicle measuring more than 3 mm was chosen as the suction target. The aspirate was placed in a 50 mL tube and allowed to settle for 15 min before washing with T-HEPES (media 199, Sigma-Aldrich; 1% PVA, Sigma-Aldrich; sodium pyruvate, Sigma-Aldrich; 200 µM D-glucose; 3mM penicillin/streptomycin, Gibco 1835954; 1% sodium bicarbonate, s8875, Sigma-Aldrich). The sediment and T-HEPES mixture were poured into a 60 mm petri dish to locate COCs using a microscope. The collected COCs were washed three times in in vitro maturation media (media 199, Gibco; 10% porcine follicular fluid, EGF 10 ng/mL, HCG 10 IU/mL, cAMP 100 μM, and PMSG 10 IU/mL) and cultured in a four-well dish. COCs were allowed to mature for 42 h, which consisted of culturing them for 22 h in hormone-supplemented media and for 20 h in hormone-free media.

NRVM were isolated according to our established protocols using a standard isolation system (Worthington Biochemical Corporation). In brief, hearts from 1–3 day old Sprague Dawley rats were harvested, minced and digested with trypsin for 16–20 hours. The next day, trypsin inhibitor was added and the tissue was further digested with collagenase. Cells were released by trituration, filtered twice, incubated for 20 min and pelleted by centrifugation. After resuspension cells were seeded in plating medium [Dulbecco’s Modified Eagle Medium (DMEM; Cellgro) with 17% Media 199 (Invitrogen), 15% fetal bovine serum (FBS; Invitrogen) and 1% penicillin/streptomycin solution (P/S; Invitrogen)] on laminin-coated glass cover slips in 24-well plates. After 72 hours, cells were further cultured in maintenance media [DMEM with 20% Media 199, 1% insulin-transferrin-sodium selenite solution (ITS; Sigma-Aldrich) and 1% P/S] in the presence of 100 μM 5-bromo-2′ deoxyuridine (BrdU; Sigma-Aldrich) for another 4 days and then treated with recombinant murine FGF23 (6His-tagged Tyr25-Val251 [Arg179Gln]; 26.1 kDa) or FGF2 (Ala11-Ser154; 16.2 kDa) (both R&D Systems) at 25 ng/ml for different time points. For treatment studies, an FGFR4 blocking antibody (human monoclonal, U3-11; U3Pharma) was used at 10 μg/ml.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
