For all experiments, only cells within six passages were used.
GnV-3 cells are one of 11 clones of GnRH-expressing cells obtained by the conditional immortalization of cultured adult rat hypothalamic cells [58] (link). GnV-3 cells express markers of well-differentiated neurons and do not express markers of glial cells [59] (link). Cells were grown in Proliferation medium consisting of Neurobasal A medium with B27 supplement (20 µl/ml, Invitrogen-Gibco), PSN (1×, Invitrogen), Glutamax I (Invitrogen), doxycycline hydrochloride (0.5 µg/ml, Sigma), FBS (10 µl/ml, Biological Industries), and βFGF (5 ng/ml, Invitrogen). Doxycycline promotes the proliferation of these conditionally immortalized cells. To induce the differentiation of GnV-3 cells, the culture medium was replaced by differentiation medium (containing Neurobasal A, B27 supplement, PSN, Glutamax I, and βFGF).

Murine endothelial cells (SVEC4-10, ATCC, Manassas, VA) were grown to confluence in DMEM supplemented with 10% fetal bovine serum on fibronectin-coated culture dishes. The fluorescent indicator 4,5-diaminofluorescein diacetate (DAF-2, Cayman Chemical Co.) was added to the medium and culture dishes were placed in an inverted position to allow MB flotation to the cell surface.

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.
