However, to determine whether the glia cells surrounding the olfactory nerve at later stages are derived from epithelioid cells emanating from the olfactory epithelium, cell lineage analyses have to be conducted.
The exact source of prions shed in saliva remains speculative; possible sources include centrifugal/retrograde passage from nerve fiber terminations in the oral nasal mucosa, or from lymphoid cells emanating from infected tonsilar or other alimentary lymphoid tissues.
In frontal sections, a stream of immunoreactive cells emanating from the ventral part of the caudate-putamen was observed in the ventral parts of the nucleus accumbens and the olfactory tubercle as well as in the ventral part of the lateral septum.
Confocal microscopy revealed a spiral of successively larger leaf progenitor cells emanating from the apical cell, thus demonstrating its continued activity.
We found that from approximately day 18 this phenotype changes to a more stellate morphology, with projections of invasive cells emanating from a central multicellular spheroid.
In contrast, chemo-residual tumor cells emanating from our short-term chemotherapy treatment model exhibited reduced HIF-1α mRNA (Fig. 1e) and protein (Fig. 1f) levels.
Although this idea has been contested on the basis that there is no experimental confirmation [ 9], the idea that all the gastrointestinal epithelial cells emanate from a single progenitor stem cell is widely accepted.
Two hypotheses regarding the origin of cross-contamination were pursued: cells emanating from the pipette tips as they were passed directly over the contamination control wells or cells ejected up out of the wells as aerosols when the cell suspension was expelled.
33 As the cerebral cortex and the eye both develop from the forebrain, the co-occurrence of forehead involvement and neurological and ophthalmological abnormalities is strongly suggestive of a single mutation affecting the neural crest cells emanating from the forebrain region.
Flip-out clones of cells emanating from ISCs can be created in the midgut epithelium by transferring flies of the UAS-FLP act-FRT-FRT-lacZ/tubGAL80ts esg-GAL4 UAS-FLP act-FRT-FRT-lacZ/tubGAL80ts°C to initiate clone prodUAS-FLP act-FRT-FRT-lacZ/tubGAL80tsiang et al., 2009).
