Exosome-Mediated Signaling in Epithelial to Mesenchymal Transition and Tumor Progression

Growing evidence points to exosomes as key mediators of cell-cell communication, by transferring their specific cargo (e.g., proteins, lipids, DNA and RNA molecules) from producing to receiving cells. In cancer, the regulation of the exosome-mediated intercellular communication may be reshaped, inducing relevant changes in gene expression of recipient cells in addition to microenvironment alterations. Notably, exosomes may deliver signals able to induce the transdifferentiation process known as Epithelial-to-Mesenchymal Transition (EMT).

Laser Transmission Spectroscopy _ LTS

Italiano

Laser Transmission Spectroscopy (LTS) is a relatively new technique capable of rapidly determining the size, shape, refractive index and number of meso- and nano-particles in colloidal suspensions. This technique relies on the measurement of the transmission of laser light through the sample as a function of wavelength (using a tunable laser). The measured extinction is then  inverted  to obtain the particle size distribution as well as information about particles shape,  structure (for example,  the presence of shells) and refractive index.
