Because processed allogenic bone blocks contain remnants of cells and other organic material, the present study examined the putative presence of major histocompatibility complex (MHC) molecules in protein extracts derived from processed allogeneic bone blocks.
The remnants of cells that produced erythrosomes could be responsible for PAS staining due to their glyco-lipid components and, more importantly, for fusion with capillaries of main circulatory system, at stages later than analyzed here.
Occasionally, samples were contaminated with residual fibrillar material, probably remnants of cell wall microfibrils (Fig. 1C).
In some areas, remnants of cell processes were observed.
Sections were stained with 1% safranin O (aq) as an unspecific cell wall counterstain, 1% chlorazol black E (in methoxyethanol) to stain g-layers [ 1, 16] or with 1% Coomassie to highlight the remnants of cell content.
Atherosclerosis is a form of arteriosclerosis in which an artery wall thickens due to chronic invasion and further accumulation of white blood cells, remnants of dead cells, cholesterol, and triglycerides [ 89].
The origin of migrated RPE cells seen in this study is unclear; there is a possibility also that these cells are remnants of RPE cells attached to the photoreceptors left from the traumatic event of the RPE tear.
Circulating cfDNA molecules are present in only limited amounts in blood of healthy individuals, since dying cells and remnants of dead cells are efficiently removed, mainly in the liver [5, 6].
This study accessed the incidence of free colorectal cancer cells or remnants of such cells in the pelvic cavity immediately after surgery, and correlates their presence with several clinicopathological parameters and survival.
However, for RAW 264.7 cells, the SEM micrographs revealed that cell morphology was not well-defined, with remnants of damaged cells, particularly after exposure to the eluates from Durabase Soft and Coe Comfort.
Active caspase 3 staining was also associated with cells with a shrunken apoptotic morphology or with irregular structures, putatively reflecting remnants of dead cells (Supplementary Fig. 4).
