Similar GGCs were more recently detected in a baboon having glandulo-metaplastic esophageal mucosa (GMEM). The aim was to assess the frequency of baboons with GMEM having GGCs. Materials and Methods: GGCs were sought in 68 consecutive baboons having GMEM. Sections were stained with H&amp;E, and with alcian blue (pH 2.5) to detect sialomucins in goblet cells (a marker of Barrett's mucosa in GMEM). Results: Two out of the 68 baboons with Barrett's mucosa (2.9%) showed GGCs. Conclusion: In similarity to humans, the Barrett's mucosa in baboons may show GGCs. Although the significance of GGCs in baboons (and in humans) remains poorly understood, their presence might not be a fortuitous event but may be linked to the molecular events leading to the development of intestinal metaplasia in Barrett's mucosa, a known pre-neoplastic mucosal change in the distal esophagus in humans.</style></abstract></record></records></xml>
