Analysis of intracorporeal knotting with invaginating
suture versus endoloops in appendiceal stump closure.
Also, with the synapses invaginating
into the presynaptic photoreceptors to a maximum measured depth of 629 nm, it is unlikely these synapses were missed in the examined sections.
They were composed of ribbons and islands of stratified squamous and respiratory epithelia, invaginating
in to the edematous stroma.
Some suggest that it appears as a separate invagination, then closes again and opens into the invaginating
When the invaginating
crypts of an inverted papilloma are filled with the cords and ribbons of a keratinizing or non-keratinizing squamous cell carcinoma, the lesion represents a conventional squamous cell carcinoma arising in an inverted papilloma, which implies a worse prognosis than that of transitional cell carcinoma.
In Drosophila, the initiation of cellularization is accompanied by the development of AJs at the invaginating
furrow canal (Tepass et al.
That this positioning is of paramount importance for the ultimate localization of the zooxanthellae becomes evident during gastrulation, when zooxanthellae are situated within invaginating
blastomeres and so become localized within the endoderm.
Deep to the fluorescently stained dots were clusters of invaginating
bottle-shaped cells slightly larger than those in the surrounding tissue (Fig.
Gastrulation in the sea urchin embryo is accompanied by the rearrangement of invaginating
The sea urchin Brachyury gene (HpTa) is transiently expressed in the lineage of secondary mesenchyme cells: first in the vegetal plate of the mesenchyme blastula, extending to the tip of the invaginating
archenteron, and finally in the secondary mesenchyme cells at the late-gastrula stage (16).
In the sea urchin embryo, myocytes arise from a subset of secondary mesenchyme that delaminates from the invaginating
