Clinics in Geriatric Medicine, 1979 Cultured normal human and animal cells are predestinued to undergo irreversible functional decrements that mimick age changes in the whole organism. When normal human embryonic fibroblasts are cultured in vitro, 50 +/- 10 population doublings occur.

The cell biology of smell [PDF]
Journal of Cell Biology, 2010 The olfactory system detects and discriminates myriad chemical structures across a wide range of concentrations. To meet this task, the system utilizes a large family of G protein–coupled receptors—the odorant receptors—which are the chemical sensors underlying the perception of smell.

Current Biology, 2006 As with the experimental sciences, the cell simulation field is largely driven by the development of new techniques, and of new tools that implement those techniques. Many techniques under development are working to increase simulation accuracy while reducing the computational burden.

Molecular Biology of the Cell, 2011 How does the nucleus move within the cell? How is the nucleus compartmentalized? How is nuclear size maintained? How is chromatin organized within the nucleus? These are a few of the questions related to nuclear cell biology addressed by our Minisymposium. Dan Starr led off with a description of how nuclei migrate in Caenorhabditis elegans.

Nature Microbiology, 2022 The past decade has revealed the diversity and ubiquity of archaea in nature, with a growing number of studies highlighting their importance in ecology, biotechnology and even human health. Myriad lineages have been discovered, which expanded the phylogenetic breadth of archaea and revealed their central role in the evolutionary origins of eukaryotes ...

NaNog: A pluripotency homeobox (master) molecule. [PDF]
, 2015 One of the most intriguing aspects of cell biology is the state of pluripotency, where the cell is capable of self-renewal for as many times as deemed necessary , then at a specified time can differentiate into any type of cell. This fundamental process

Cell Biology of the Mitochondrion [PDF]
Genetics, 2017 AbstractMitochondria are best known for harboring pathways involved in ATP synthesis through the tricarboxylic acid cycle and oxidative phosphorylation. Major advances in understanding these roles were made with Caenorhabditiselegans mutants affecting key components of the metabolic pathways.
