RIKEN Stem cells have the unique ability to become any type of cell in the body. Given this, the possibility that they can be cultured and engineered in the laboratory makes them an attractive option for regenerative medicine. However, some conditions that are commonly used for culturing human stem cells have the potential to introduce contaminants, thus rendering the cells unusable for clinical use. These conditions cannot be avoided, however, as they help maintain the pluripotency of...

A University of Colorado Cancer Center study recently published in the journal Cell Reports and presented today at the American Association for Cancer Research (AACR) Annual Conference 2014 shows that the cellular process of autophagy in which cells "eat" parts of themselves in times of stress may allow cancer cells to recover and divide rather than die when faced with chemotherapies. Autophagy, from the Greek "to eat oneself," is a process of cellular recycling in which cell organelles...

The long and the short of telomeres In captivity, grey parrots are often kept in social isolation, which can have detrimental effects on their health and wellbeing. So far there have not been any studies on the effects of long term social isolation from conspecifics on cellular aging. Telomeres shorten with each cell division, and once a critical length is reached, cells are unable to divide further (a stage known as 'replicative senescence'). Although cellular senescence is a useful...

Stowers team reports genome-wide analysis of genes that drive cell division in a multicellular organism In textbooks, the grand-finale of cell division is the tug-of-war fought inside dividing cells as duplicated pairs of chromosomes get dragged in opposite directions into daughter cells. This process, called mitosis, is visually stunning to observe under a microscope. Equally stunning to cell biologists are the preparatory steps cells take to ensure that the process occurs safely....

Experts analyze baker's yeast to discover potential for combating neurological conditions like Parkinson's and even cancer A humble ingredient of bread – baker's yeast – has provided scientists with remarkable new insights into understanding basic processes likely involved in diseases such as Parkinson's and cancer. In a new study published today (Monday March 31) in the prestigious journal PNAS (Proceedings of the National Academy of Science), the team from Germany, Leicester, and...

Researchers from Warwick Medical School have discovered the key role of a protein in shutting down endocytosis during mitosis, answering a question that has evaded scientists for half a century. The study, published today in the journal eLife, is the first to outline the role of actin, a protein, in shutting down clathrin-dependent endocytosis during mitosis. Endocytosis is the process by which cells absorb molecules that are too large to pass through the plasma membrane, such as...

TAU researchers find inhibition of a basic cellular process may contribute to the mysterious disease Surprisingly little is known about schizophrenia. It was only recognized as a medical condition in the past few decades, and its exact causes remain unclear. Since there is no objective test for schizophrenia, its diagnosis is based on an assortment of reported symptoms. The standard treatment, antipsychotic medication, works less than half the time and becomes increasingly ineffective over...

Researchers at the Cell Cycle Research Group of the Bellvitge Institute of Biomedical Research (IDIBELL) led by Ethel Queralt have reported in the journal PLoS Genetics an article which delve into the regulator mechanisms of mitosis, a key stage of the cell-cycle for the correct transmission of genetic information from parents to sons. Cell-cycle Cells in all organisms grow and divide into two daughter cells by an ordered sequence of events called "cell cycle". Basically, the cells have...

Salk Institute Findings may lead to much-needed therapies for kidney disease Diseases affecting the kidneys represent a major and unsolved health issue worldwide. The kidneys rarely recover function once they are damaged by disease, highlighting the urgent need for better knowledge of kidney development and physiology. Now, a team of researchers led by scientists at the Salk Institute for Biological Studies has developed a novel platform to study kidney diseases, opening new avenues...

A rudimentary form of life that is found in some of the harshest environments on earth is able to sidestep normal replication processes and reproduce by the back door, researchers at The University of Nottingham have found. The study, published in the journal Nature, centers on Haloferax volcanii — part of a family of single-celled organisms called archaea that until recently were thought to be a type of bacteria. The findings, led by scientists from the University's School of Life...


Word of the Day
endocarp
  • The hard inner (usually woody) layer of the pericarp of some fruits (as peaches or plums or cherries or olives) that contains the seed.
This word comes from the Greek 'endon,' in, within, plus the Greek 'kardia,' heart.
