The new system was featured in a recent issue of the publication "Microscopy Today," in an article entitled "Red/Green Dual Fluorescence Detection of Both the Nucleus and Nucleolus in Living Cells.
The sinus histiocytes exhibit enlarged vesicular nuclei with well-defined nuclear outlines, a single prominent nucleolus, and abundant pale eosinophilic, occasionally foamy cytoplasm containing variable numbers of intact lymphocytes.
A number of oogonia appeared along the follicular walls (16-18 [micro]m in diameter) and had a round nucleus containing a nucleolus in its center.
This is the nucleolus that directs what acquisitions are made and creates strategic alliances, develops proprietary technology and patents that bring the expertise and create the real value for the Mundus Group.
Many had degenerating ghost-cell appearance (Figure 3, b and c) and lacked the characteristic eccentric shape and conspicuous nucleolus expected for the normal myenteric plexus GCs.
Histiocytes exhibiting enlarged vesicular nuclei with well-defined nuclear membrane, single prominent nucleolus, and abundant eosinophilic or foamy cytoplasm in which intact lymphocytes may be found in variable numbers are the hallmark of RDD.
In addition to the CK2 inhibitor CX-4945, Cylene's Nucleolus Targeting Technology has generated Quarfloxin (CX-3543), a small molecule agent that is in Phase II development for the treatment of carcinoid/neuroendocrine tumors (C/NET).
The most important ultrastructural features are prominent nucleolus with dispersed nucleolonema and specialized cell junctions of the zonula adherens type, true intercellular bridges, identical to those normally found between spermatocytes and between spermatids.
Cylene has created a diverse portfolio of product candidates, including novel inhibitors of cancer-linked serine/threonine protein kinases, as well as innovative nucleolus targeting agents (NTAs).
A visible nucleolus is present in both the CTCs and the cells shown from the touch preparation of the original needle biopsy from 4 years prior.
Many commercialized cancer therapeutics act on or through the nucleolus, but quarfloxin is the first agent designed to directly target a key function within the nucleolus.
The nuclei are round and located at the base of the cell (in larger ducts) and show either no nucleoli or only a small distinct nucleolus (Figure 7, A).
