proliferative cells
Monoclonal antibodies (McAb) to Ki-67, BrdU and OKT9 were used in APAAP technique for determining the proliferative cells of 46 myelodysplastic syndromes (MDS) with 16 serving as normal controls.
      
The ratio of CD8+ in proliferative cells was analyzed by flow cytometry.
      
CD8+ cells, accounting for a high proportion in proliferative cells, had a specific cytotoxicity to leukemia cells from which antigen peptides were prepared, suggesting that these CD8+ cells were CTLs specific to leukemia cells.
      
Relative resistance of a strain to the hyperacute or high-dose mode of death is not necessarily correlated with resistance to the midlethal mode, which is believed to be the result of damage to the proliferative cells of the midgut.
      
Using novel inferential procedures, we estimate the generation-time distribution and the offspring distribution of proliferative cells, and the waiting-time distribution of resting cells.
      
In the elongation zone of Allium roots a certain fraction of cortical cells undergo DNA replication during transition from newborn non-proliferative cells to mature cells.
      
ES3A may be suitable for quantification of germinative or proliferative cells.
      
Epidermal homeostasis depends on two types of proliferative cells, keratinocyte stem cells (KSCs), and transit amplifying (TA) cells.
      
An account is given of a combined in vivo- and in vitro - method for synchronization of proliferative cells of human tumours.
      
Proliferative cells had a sodium concentration that was twice that of resting cells, suggesting that Na may play an important role in the regulation of DNA- and protein-synthesis in chondrocytes.
      
During the interphase of steady-state proliferative cells, the volume density and numerical density of the Golgi apparatus decrease to reach minimum values in late-interphase cells, characterized by their greatest length.
      
High levels of AS1 expression were found in tissues with highly proliferative cells, which further suggests a role in cell division and early cell differentiation.
      
To determine the distribution of neoblasts, we focused on proliferating cell nuclear antigen (PCNA), which is present in proliferative cells.
      
Reactive conditions such as angiolymphoid hyperplasia with eosinophilia showed an intense positive reaction to blood group substances of the endothelial proliferative cells.
      
Factor-XIIIa-positive cells were consistently antigen-H-negative and represented only a small percentage (usually less than 10%) of the proliferative cells.
      
Propidium iodide and bromodeoxyuridine were used to recognize necrotic and proliferative cells.
      
Detailed analysis of the epithelium showed that proliferative cells were more numerous at the base of the gland at the earliest stage (11 weeks) but concentrated in the pit/neck regions by 13-14 weeks.
      
Effect of salt on cell proliferation andN-methyl-N'-nitro-N-nitrosoguanidine penetration to proliferative cells in the forestoma
      
[3H]MNNG at a concentration of 40 μg/ml did not penetrate to the proliferative cells in the forestomach and no effect of salt pretreatment on carcinogen penetration was seen.
      
The low penetration of [3H]MNNG to proliferative cells in the forestomach epithelium may explain why this concentration of MNNG given in drinking water over several weeks usually does not induce squamous cell carcinomas in the forestomach.
