Summary: | The present study was undertaken to provide an ultrastructural identifi cation of the different cells in the islets
of the camel pancreas. Tissue samples were obtained from ten healthy, adult camels and processed for electron
microscopy. The islets are composed of abundant, centrally located beta; β-cells, alpha; α-cells are present at
the very periphery of the islets, while delta; δ-cells are distributed among both β- and α-cells.
These cells were easily distinguished on the basis of the morphology of secretory granules. The granules of the
β-cells varied greatly in shape and size and both “dense and pale” granules could be identifi ed. The α-cells have
a homogeneous rounded core of moderate to high electron density granules. The δ-cells contain large spherical
to irregular shaped granules of variable electron density.
Our fi ndings of the single-humped camel pancreas make additional contribution to those found in other
mammalian species.
