Endocrine-like cells in the chick embryo thymus express ultrastructural features of piecemeal degranulation

Authors


Abstract

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. © 2005 Wiley-Liss, Inc.
