TNTs change the cell shape

The Very Concept Of Cell: TNT challenges

Cells in our bodies have the ability to speak with one another much like humans do. This communication allows organs in our bodies to work synchronously; which in turn, enables us to perform the remarkable range of tasks we meet on a daily basis. One of this mean of communication is ‘tunneling nanotubes’ or TNTs.…

Bone Marrow transplants

Focus On Future Of Stem Cells: Conference By Annual RegenMed SA

Doctors regularly perform stem cell transplants, also known as bone marrow transplants, to replace cells damaged by chemotherapy. The stem cells, or the body’s raw material, that make this transplantation possible will be the topic of a two-day event titled, “Fifth San Antonio Conference on Stem Cell Research & Regenerative Medicine.” The conference, at the…

Brain Development: By The Interactions of mRNAs and miRNAs

To study the method of brain development, one of the big challenges is cell classification. A problem compounded by the fact that same cell type can look different depending on the method of classifying it. Whether by cell shape, gene expression profile, electrophysiological firing pattern, or selective vulnerability to certain diseases. “There are many individual cell types…

A Dramatic Pattern of Bone Growth in Female Mice

In ‘game-changing’ finding, bone mass rose 800% after signals were blocked in brains of mice. UCLA and UC San Francisco scientists have found that blocking some signals from a small number of neurons in the brain causes female, but not male, mice to build super-strong bones. Researchers published their data in the journal Nature Communications. “We…

Neurons Integrate Better With Muscle Grown On Grooved Platforms

Growing muscle tissue on grooved platforms helps neurons more effectively integrate with the muscle, a requirement for engineering muscle in the lab that responds and functions like muscle in the body, University of Illinois researchers found in a new study. Such engineered muscle with integrated nerves has applications in reconstructive and rehabilitative medicine, as well as for engineered biological machines or robots.

For Reproductive Success, Staying In Shape Is Vital

Cells must keep their shape and proportions to successfully reproduce through cell division, finds new research from the Francis Crick Institute and King's College London. The research, published in Nature Communications, reveals a fundamental biological basis for scaling, where cells maintain their proportions as they grow or shrink. This principle is seen throughout life, from single cells through to complex organisms, but its biological origins have remained a mystery.

Want To Preventing Breast Cancer? Thanks To New Drugs

Breast cancer will strike 1 in 8 women in her lifetime. But women who face an increased risk of being that one unlucky patient may improve their chances with three prescription medications, according to a new report. For women at average risk of breast cancer, the harms of the drugs clearly outweigh their benefits, the panel said.

The new recommendations expand the medication toolkit that can be used to ward off breast cancer. For the first time, the task force added a class of drugs called aromatase inhibitors to the cancer-prevention lineup. These drugs include anastrozole (known commercially as Arimidex), exemestane (Aromasin) and letrozole (Femara).

The Developing Embryo: How Stem Cells Self-organize

New study uses live imaging to understand a critical step in early embryonic development — how genes and molecules control forces to orchestrate the emergence of form in the developing embryo. The study findings could have important implications for how stem cells are used to create functional organs in the lab, and lead to a better understanding of the underlying causes of gastrointestinal birth defects.

Multiple Sclerosis: Protecting Oligodendrocytes May Reduce It

A small molecule, Sephin1, may be able to significantly delay harm to nerve cells caused by multiple sclerosis, a disabling immune-mediated disease that damages nerve fibers in the brain and spinal cord. In the journal Brain, a team based at the University of Chicago show that treating mice suffering from a mouse model of MS with Sephin1 (selective inhibitor of a holophosphatase) was able to "delay the loss of myelin and postpone the onset of debilitating disease."
