Characteristic features of ghrelin cells in the gastrointestinal tract and the regulation of stomach ghrelin expression and production

Figure 2 Changes in ghrelin mRNA levels and the densities of ghrelin-ip cells during the postneonatal period in the rat stomach[20]. The data in (A) and (B) are shown as the % of 1-wk-old (1 wk) rats (100%) and each bar represents the mean ± SE (n = 3). A: Ghrelin mRNA levels in the male stomach; B: Ghrelin mRNA levels in the female stomach; C: The densities of ghrelin-ip cells (cells/mm²) in the male stomach; D: The densities of ghrelin-ip cells (cells/mm²) in the female stomach.
