Prior to 2007, exosomes were largely considered to be tiny “trash sacs” thrown out of living cells. Around 2007, it as discovered that exosomes carry RNAs and miRNAs, along with other molecules to regulate the expression of genes between cells. This discovery paved the way for the scientists to search for improved techniques for the exploitation of exosomes in treating diseases. [Read more…]
Taking EV characterization to the next level with ONI’s Nanoimager
Extracellular vesicles (EVs) are known for their role in facilitating wide range of intercellular communication such as regulation of the immune response and stem cells differentiation.
What is an extra-cellular vesicle?
EVs are membrane-enclosed particles ranging in size from 30nm to 300nm and their characteristic depend on the cell type releasing them. Often they will carry cargo of active molecules like RNA, DNA, proteins, metabolites and lipids. Moreover, EVs can be found in most biological fluids with the ability to cross biological barriers, and in the case of pathological conditions, the composition of the cargo will be distinctive to the disease. Altogether, these features have led to intense research into the potential role of EVs for diagnostics, biomarkers and as vehicles for drug delivery. [Read more…]
The Exosome Revolution is Here
Exosomes have recently exploded in popularity, with companies developing exosome-based diagnostics, therapeutics, and cosmeceuticals. Although they were discovered more than 30 years ago, it was not until recently that the scientific community began to give credit to exosomes for a range of promising traits. [Read more…]
The Rise of Stem Cell Exosomes and their Applications
Exosomes are small vesicles ranging from 30-100nm in size that are found in nearly all eukaryotic fluids and facilitate a range of important cellular functions. In the early 1960s, Ernest A. McCulloch and James E. started several experiments leading to the discovery of stem cells. It was not until much later in 1987 that exosomes were first identified in a mammalian reticulocyte (red blood cell)[1] and not until 2007 that exosome-mediated transfer of mRNAs and microRNAs was identified as a “novel mechanism of genetic exchange between cells.”[2] [Read more…]
Top 4 Most Richly Funded Exosome Startups
In recent years, exosome start-up companies have been the recipients of hundreds of millions of dollars in investor funding. Clearly, investors are feeling favorable toward companies developing exosome products and there is a growing belief that the industry is poised for growth. [Read more…]
