The gap between stem cell research and regenerative medicine just became a lot narrower, thanks to a new technique that coaxes stem cells to take the first step to specialization for the first time in a laboratory. Researchers demonstrated that not only is it possible for mouse embryonic stem cells to form three distinct germ layers in the lab, but also that it requires correct timing, chemical factors and mechanical environment.
Pioneering 'tweezers' that use ultrasound beams to grip and manipulate tiny clusters of cells under electronic, push-button control could lead to life-changing medical advances, such as better cartilage implants that reduce the need for knee replacement operations.
A new technology under development at the Georgia Institute of Technology could one day provide more efficient delivery of the bone regenerating growth factors with greater accuracy and at a lower cost.
Researchers have developed the first mobile application for Android phones that analyses ab1 DNA sequencing files, which enables science professionals and amateur enthusiasts to engage in scientific analysis on the go, from the convenience of their mobile phones.
Researchers demonstrate that the technique may be used to visualise 3D specimens up to 34 tomographic sections in depth. These new results compare well with sectioned images collected from a confocal microscope but have the added advantage of strong phase contrast, which removes the need for sample labelling or staining.
Cells have their own tiny skeletons that are responsible for many important cellular functions. Scientists have developed novel fluorescent probes for imaging these important structures easily and with unprecedented resolution.
