glis3 restricts pit1-precursors during zebrafish adenohypophysis development

Supporting Data_Rurale et al (Excel file): this dataset supports the study investigating the role of glis3 in zebrafish adenohypophysis (AH) development and function. The study analyzes the effects of glis3 knockdown (KD) on pituitary cell differentiation, hypothalamic-pituitary function, and osmoregulation.

This dataset provides all raw numerical data corresponding to the graphs presented in the main text figures and supplementary materials of this study. Depending on the experiment, statistics were calculated using Student-t-test or Mann-Whitney Test using GraphPad Prism 10 Software. Statistically significant values are colored in red.
