Cell Labeling News and Research

RSS

One way to study cells is to tag specific molecules with reporter proteins, that can be detected using laboratory methods. This allows the study of protein location, function and production.

Scientists discover orderly structure hidden within bacterial biofilms

Bacteria are traditionally imagined as single-cell organisms, spread out sparsely over surfaces or suspended in liquids, but in many environments the true bacterial mode of growth is in sticky clusters called biofilms.

Non-invasive CGC examination for precision diagnosis of ocular surface diseases in live rabbit eyes

A Korean research team led by Professor Ki Hean Kim, Ph.D. candidates Seonghan Kim and Jungbin Lee (Department of Mechanical Engineering) at POSTECH, in collaboration with Professor Chang Ho Yoon (Department of Ophthalmology) of Seoul National University Hospital and Professor Young-Ho Jung (Department of Ophthalmology) of Eulji Hospital, has successfully demonstrated the non-invasive CGC examination in live rabbit eyes.

Using sugar molecules for in vivo tracking of unlabeled stem cells

A Johns Hopkins Medicine scientist who spent 30 years figuring out how to put chemical labels into cells to track their movement in living tissues has found that certain self-renewing stem cells have built-in tracers -; made out of sugars -; that can do the job without added chemical "labels" when injected into mouse brains.

Magnetic core-shell iron nanowires can be used for noninvasive medical imaging

Living cells inside the body could be placed under surveillance--their location and migration noninvasively tracked in real time over many days--using a new method developed by researchers at KAUST.

Novel MRI contrast agent for early detection of brain metastases

A group of researchers led by Leif Schroeder from the Leibniz-Forschungsinstitut fuer Molekulare Pharmakologie have found a way to detect metastases in certain types of cancer in the brain at an early stage, using only minimal amounts of contrast agent.

Researchers successfully develop imaging technology of conjunctival goblet cells

Goblet cells are epithelial cells that produce mucins and disperse tears which help the surface of eyes maintain the wet environment. Goblet cells are closely related to autoimmune disease including dry eyes and chemical burns. Therefore, it is very important to examine the status of goblet cells to better understand and diagnose ocular disease.

Researchers develop new method to visualize whole-body cancer metastasis at single-cell level

Researchers at the RIKEN Quantitative Biology Center and the University of Tokyo have developed a method to visualize cancer metastasis in whole organs at the single-cell level.

Researchers develop new technique to capture neuron activity

Many cognitive processes, such as decision-making, take place within seconds or minutes. Neuroscientists have longed to capture neuron activity during such tasks, but that dream has remained elusive -- until now.

HSCI researchers use color tagging system to track development of blood stem cells

Harvard Stem Cell Institute (HSCI) researchers have used a colorful, cell-labeling technique to track the development of the blood system and trace the lineage of adult blood cells travelling through the vast networks of veins, arteries, and capillaries back to their parent stem cell in the marrow.

New chemical probe could tag cells for detection by MRI

The need to non-invasively "see" and track cells in living persons is indisputable - a boon to both research and development of future therapies. Emerging treatments using stem cells and immune cells are poised to most benefit from cell tracking, which would visualize their behavior in the body after delivery. Clinicians require such data to speed these cell treatments to patients.

Researchers identify dazzling new method for visualizing neurons

Researchers have discovered a dazzling new method of visualizing neurons that promises to benefit neuroscientists and cell biologists alike: by using spectral confocal microscopy to image tissues impregnated with silver or gold.

HSCI researchers find surprising similarities between SMA and ALS

Harvard Stem Cell Institute researchers studying spinal muscular atrophy (SMA) have found what they term "surprising similarities" between this childhood disorder that attacks motor neurons and amyotrophic lateral sclerosis (ALS), more commonly known as Lou Gehrig's disease.

New noninvasive technique for tracking stem cells after transplantation

A new, noninvasive technique for tracking stem cells after transplantation - developed by a cross-disciplinary team of radiologists, chemists, statisticians and materials scientists at the Stanford University School of Medicine - could help surgeons determine whether a procedure to repair injured or worn-out knees is successful.

New research reveals how acute stress primes brain for improved performance

Overworked and stressed out? Look on the bright side. Some stress is good for you. "You always think about stress as a really bad thing, but it's not," said Daniela Kaufer, associate professor of integrative biology at the University of California, Berkeley.

New positively-charged nanoparticles can be useful MRI agents to monitor transplanted islet cells

In a study to investigate the detection by MRI of six kinds of positively-charged magnetic iron oxide nanoparticles designed to help monitor transplanted islet cells, a team of Japanese researchers found that the charged nanoparticles they developed transduced into cells and could be visualized by MRI while three kinds of commercially available nanoparticles used for controls could not.

Johns Hopkins team reconstitutes single stem cells' family tree

A Johns Hopkins team has discovered in young adult mice that a lone brain stem cell is capable not only of replacing itself and giving rise to specialized neurons and glia - important types of brain cells - but also of taking a wholly unexpected path: generating two new brain stem cells.
