This study shows that PI4-kinase A is essential for postnatal survival of GnRH neurons, leading to infertility in knockout mice, but not for embryonic development.

The paper investigates Sox2-expressing cells in mouse pituitary and their role in postnatal gonadotroph differentiation, finding that marginal zone Sox2 cells act as stem cells requiring PI4 kinase A for differentiation.

This study uses scRNA-seq to analyze Sox2-expressing cells in rat pituitary, identifying heterogeneity in folliculostellate cells and their potential stem-like properties.
