The vitelline cells outside the eggshell probably leaked into the ootype during or after perfusion because the anesthetic used on the mouse host appears to relax the sphincter at the end of the vitelline duct allowing vitelline cells to leak into the ootype after eggshell formation.

Secretory Proteins of , Salivary Glands: Structural Motifs and Assembly Characteristics of a Novel d Daneholt 1977; Grossbach 1977). Cytogenetic studies by Beermann (1961) and Grossbach (1969) led to the proposal that BRs contain genes encoding secretory proteins, the major product of the salivary gland. Secretory proteins assemble in vivo into insoluble silken threads that larvae use for feeding and construction of housing and pupation tubes.

The Formation of Mussel Byssus: Anatomy of a Natural Manufacturing Process,s, the byssus is robust, tough, devoid of living cells, and disposable. Unlike plastics, however, it is ultimately biodegradable. Structural and mechanical analysis of the byssus reveals an exquisitely complex design at every level from the microcellular solid in the plaques to the fiber gradients i

These so-called vitelline cells serve as a food source during embryogenesis within the egg in addition to being responsible for eggshell production. In Fig.1, there are vitelline cells on both the inside and outside of the eggshell. This egg was formed pri

Secretory Proteins of , Salivary Glands: Structural Motifs and Assembly Characteristics of a Novel . More than a century ago, Balbiani (1881) described large puffs on these chromosomes. These puffs, referred to as Balbiani rings (BRs), were recognized by Beermann (1952, 1961) as loci of tissue-specific gene expression and are now known to be sites of intensive transcription (Pelling 1964; Case an
