Cellular differentiation

Cellular differentiation is a concept from developmental biology describing the process by which cells acquire a "type". The morphology of a cell may change dramatically during differentiation, but the genetic material remains the same, with few exceptions. A cell that is able to differentiate into many cell types is known as pluripotent. These cells are called stem cells in animals and meristematic cells in higher plants. A cell that is able to differentiate into all cell types is known as totipotent.

In mammals, only the zygote and early embryonic cells are totipotent, while in plants, many differentiated cells can become totipotent with simple laboratory techniques.

In Cytopathology the level of cellular differentiation is used as a measure of Cancer progression.

Cholesterol-lowering Drugs Don't Offset Healthy Choices, Study Finds
Within the medical field, it is often assumed that patients view cholesterol-lowering medications (or statins) as a license to eat whatever they like -- they figure their medication has them covered, so a steak here and there won't hurt. However, a new study finds that such patients don't tend to adopt unhealthy diets when prescribed statins.

My Whole Cell Twitter Interview
Laura Bonetta wrote an excellent article for the science journal Cell recently in which she quoted various science types who use Twitter on the subject of whether or not scientists should be tweeting. It’s a topic I’ve discussed more generally regarding scientists’ use of social media and online networking communities.Anyway, she asked my opinion on [...]

To Evade Chemotherapy, Some Cancer Cells Mimic Stem Cells
Anti-cancer treatments often effectively shrink the size of tumors, but some might have an opposite effect, actually expanding the small population of cancer stem cells believed to drive the disease, according to new findings.

Multifunctional polymer neutralizes both biological and chemical weapo
In an effort to mirror the ability of biological tissues to respond rapidly and appropriately to changing environments, scientists have synthesized a single, multifunctional polymer material that can decontaminate both biological and chemical toxins.

Similar Decline Over Decades In Cardiovascular Disease Rates For Peopl
Adults with and without diabetes have benefited similarly from the decline in cardiovascular disease (CVD) rates over the last several decades, according to a study funded by the National Heart, Lung, and Blood Institute (NHLBI). However the study, which is published in the November 24 issue of the Journal of the American Medical Association, found that people with diabetes still have twice the risk of cardiovascular disease compared to people without diabetes.

SOHO Prepares For Comet McNaught
Recently, sky watchers in the Northern Hemisphere have been enjoying the sight of Comet McNaught in the twilight sky. Now, solar physicists using the ESA-NASA SOHO spacecraft are getting ready for their view. For four days in January, the comet will pass through SOHO's line of sight and could be the brightest comet SOHO has ever seen.

Magnetic, Luminescent Nanoparticles Set New Standard
