A. Compared with normal cells, the morphology and structure of cancer cells have changed significantly B. After cancer, the cells lose their ability to divide and quickly age and apoptosis C. The surface of cancer cells changes and are easy to metastasize D. Under appropriate conditions, cancer...
摘要: Our studies indicate that by presently accepted criteria, MRC-5 cells-in common with WI-38 cells of similar origin-have normal characteristics and so could be used for the same purposes as WI-38 cells.关键词:Humans Lung Arboviruses Adenoviridae Herpesviridae Vaccinia virus Cell Line Hela...
cells, which are vertical cells in the honeycomb that are larger than normal. After hatching, the virgin queens are fedroyal jelly, a substance produced by the salivary glands of the workers. When not fed a diet consisting solely of royal jelly, virgin queens will develop into workers. ...
and its susceptibility to viruses infective for man1,4, explain the value of such material for the isolation of viruses and in the development of vaccines5–8. We have developed another strain of cells, also derived from foetal lung tissue, taken ...
Malignant progression of a mouse fibrosarcoma by host cells reactive to foreign body (gelatin sponge) The QR regressor tumour (QR-32), a fibrosarcoma which is unable to grow progressively in normal syngeneic C57BL/6 mice, was able to grow progressively in 1... F Okada,M Hosokawa,J-I Hamad...
Protein granule development in the starchy endosperm of normal maize (inbied line, W46A) was studied with optical and electron microscopy. The granules wer... U Khoo,MJ Wolf - 《American Journal of Botany》 被引量: 196发表: 1970年
Specifically, inhibitory receptors interact with MHC class I molecules expressed on normal cells and contribute to the self-tolerance of NK cells, while activating receptors sense the signals of cellular stress associated with viral infection or tumorigenesis when virus-infected cells or tumor cells ...
Objective: Autotransplantation with the use of teeth bank can add a new dimension to treatment planning. In this aspect, it is compulsory to preserve living cells and tissues at a structurally-intact status. The purpose of this study was to examine the effect of long-term cryopreservation with...
The integrity of the EZ and ELM was denoted as the integrity within 3.0 mm of the central fovea. The DRIL was described as the disorder of the boundary among the ganglion cells, the inner plexiform layer, the inner nuclear layer, and the outer plexiform layer, as previously reported [8]....
Although many cells are involved in this process, little is known about the contribution of MCs in this pathology. MCs are distributed in lungs and mucosal tissues and contribute to host-defence against bacterial infections12. In humans, MCs are classified as tryptase + MCs (MCT), ...
