| An extensive literature search failed to uncover specific documentation of PI uptake by pinocytosis. |
|
| It is possible that the chemical can gain entry into cells as small, colloidal particles via phagocytosis or pinocytosis and may also enter dead, dying or damaged cells. |
|
| However, small areas of low emission could be found in the cytoplasm, showing that the compound was taken up by the cells, probably by pinocytosis. |
|
| The four types of chemical transport systems through cell membranes are diffusion, facilitated diffusion, active transport, and pinocytosis. |
|
| Although inefficient, pinocytosis operates in the slow absorption of proteins and particles in the intestine and respiratory tract. |
|
| Large molecules, such as proteins and solid particles, are often transported by pinocytosis. |
|
| Smaller nanoparticles were internalized by endocytosis or pinocytosis, but no effect on embryo development was observed. |
|
| Insoluble aerosols that cross the alveolar wall by pinocytosis may be absorbed into the circulatory system after first entering the porous lymphatic capillaries. |
|
| Solids are not absorbed through the skin because the skin is generally not covered with liquid and because pinocytosis does not operate in dead cells. |
