The neuroglial cells of ectodermal origin, i.e., astrocytes, oligodandrocytes and ependymal cells
were in abundance in the treated groups as compared to the control group (Figs.
Later it was found that not only embryonic CNS but also adult CNS possess the ability to generate neurospheres forming cells in vitro, including neural epithelial progenitor (NEP) cells, radial glial cells, SVZ cells, and ependymal cells
, that clonigenically generate neurons, astrocytes and oligodendrocytes in vivo (16).
Furthermore, a thin layer of cells that was similar with ependymal cells
located in the interior marginal area of the pars distalis, and margin on hypophyseal cleft.
In fetal brain, p-mTOR expression was strong in the cytoplasm of ependymal cells
with their glial fibrils (Figure 1(h)), choroid plexus epithelial cells (Figure 1(i)), and pia mater, while it was faint in the nuclei of neuronal cells in the subventricular zone and cortical plate.
MPIOs are found in microglia, ependymal cells
, and oligodendrocyte progenitor cells in addition to being in NSCs, thereby providing a nonspecific tracking method .
Consistent SVA IHC staining occurred at the transitional epithelium of the renal pelvis and the urinary bladder (Figure 1, panel D) of 4 piglets; within epithelial cells of the choroid plexus of the cerebrum (8 piglets) and the tongue (5 piglets); and at the ependymal cells
of the choroid plexus, vascular endothelium, and the enterocytes of the villi of the small intestine (2 piglets) (Table 2, http://wwwnc.cdc.gov/EID/article/22/7/15-1583-T2.htm).
Ependymomas arise from the ependymal cells
lining the central canal of the spinal cord; four subtypes have been described: cellular, papillary, clear cell, and tanicytic.
By contrast, glial cells comprise about 90% of the total cell content in the CNS and are classified as microglia and macroglia (astrocytes, oligodendrocytes, and ependymal cells
These infiltrates mainly consist of autoreactive lymphocyte T cells, macrophages, microglial cells, ependymal cells
, astrocytes, and mast cells, which have the capacity to enter the CNS and incite a proinflammatory reaction, resulting in local tissue injury [3-5].
Occasionally, ependymal cells
of the spinal cord were also positive.
(42,43) Apart from lymphatic endothelium, D2-40 has been reported to be immunoreactive in mesotheliomas (44,45) and, in the CNS, in choroid plexus epithelium, ependymal cells
, subependymal areas, and the leptomeninges.
In situ hybridization studies needed to determine whether expression includes neuronal and ependymal cells
were not reported.
