Endocrine-like cells in the chick embryo thymus express ultrastructural features of piecemeal degranulation.
The endocrine-like cells of the chick embryo thymus were studied by transmission electron microscopy and a highly characteristic pattern of cell secretion referred to as piecemeal degranulation (PMD) was identified. This is the first description of PMD in embryonic cells.
