The finding that Cajal cells express c-kit (CD117), a tyrosine kinase, is a considerable development.
Ten large magnification areas were counted in the same specimen from each case, and the number of Cajal cells was quantitatively determined.
It was determined that the Cajal cells were encountered more frequently in the control group.
The number of cells in 10 separately screened areas was calculated and the total number of Cajal cells in the areas, 0-3, 4-8, and >8 cells were regarded as sparse, few and many, respectively.
c-kit positive Cajal cells, which are easily distinguished from the mast cells in the UPJ, were demonstrated in this study.
Gastrointestinal stromal tumours are mesenchymal tumours of the digestive tract that originate from intestinal cajal cells and account for 0.
Because of the immunohistochemical and ultrastructural similarities of Cajal cells and GISTs, a histogenetic origin of GISTs from Cajal cells has been proposed.
16) In both cases, these PDGFRA-positive cells could be the normal counterpart of IFPs (and PDGFRA-driven GISTs), as happens with Cajal cells for KIT-driven GISTs.
The submucous layer was thickened with an increased number of Cajal cells, and there was thick, high-density collagen IV and alpha-actin.
Both types of cells express the CD 117 protein, but Cajal cells do not stain for CD 34 nor for other muscle cell antigens frequently seen in GIST cells.
