Mining transcriptomic data for gestational diabetes mellitus: What public datasets reveal

Figure 2 The dataset counts and sample sizes across four major categories in gestational diabetes mellitus transcriptomic studies. From the innermost to the outermost ring, the concentric layers represent: (1) Broad tissue categories (placenta-related, blood and its components, pancreas/islet-related and others); (2) The number of datasets assigned to each subcategory; and (3) The cumulative sample size for each category. For example, within the placenta-related category, 19 datasets focusing on placenta were identified, together comprising 1189 samples. PBMCs: Peripheral blood mononuclear cells; sEVs: Secreted extracellular vesicles.
