 #ALT#Imaging Thick Samples of Large Model Organisms

Research projects transition from findings made at the single cell or subcellular level to more complex multicellular invertebrate and vertebrate model organisms to determine clinical relevance. In this article we discuss the challenges with laser scanning confocal microscopy (LSCM) and the solutions available.

 Ultrasensitive method for direct detection of circulating tumor cells in blood
 
Ultrasensitive method for direct detection of circulating tumor cells in bloodTumor cells circulating in blood are markers for the early detection and prognosis of cancer. However, detection of these cells is challenging because of their scarcity. In the journal Angewandte Chemie, scientists have now introduced an ultrasensitive method for the direct detection of circulating tumor cells in blood samples. The gold standard for measuring has been with fluorescence, but it is too slow to see this short, high burst of heat.
 
 
 Sensing temperature inside cells using a fluorescent nano-thermometer
 
Sensing temperature inside cells using a fluorescent nano-thermometerThe Rice lab of chemist Angel Martí revealed the technique in a Journal of Physical Chemistry B paper, describing how it modified a biocompatible molecular rotor known as boron dipyrromethene (BODIPY, for short) to reveal temperatures inside single cells. The molecule is ideally suited to the task. Its fluorescence lasts only a little while inside the cell, and the duration depends heavily on changes in both temperature and the viscosity of its environment.
 
 
 Red Fluorescent Protein Helps Explain Why Lung Tumors Turn Aggressive
 
Red Fluorescent Protein Helps Explain Why Lung Tumors Turn AggressiveLung cancer is the number 1 killer among cancers, especially when it is of the non-small cell type. Among these, adenocarcinomas are the most common and aggressive type. These tumors also show a strong tendency to show dedifferentiation, or loss of the features that characterize a mature lung cell.
