What is Liquid biopsy?
Liquid biopsy is a non-invasive diagnostic technique that allows the detection of tumor material from a body fluid sample. This technique will serve to improve the diagnosis, prognosis and follow-up of any tumor, and estimate its probabilities of metastasis, the event with the greatest clinical impact today in oncology. Liquid biopsy is considered the technology with the greatest potential for impact on the oncology diagnostic market.
Nasasbiotech is developing a new approach in the field of liquid biopsy from the analysis of circulating tumor cells (CTC), the circulating tumor DNA (ctDNA) and the extracellular vesicles (EVs). These vesicles are one of the main mediators of cell-cell communication and they are revolutionizing the field of liquid biopsy as carriers of nucleic acids (DNA, RNA, miRNA…), proteins and lipids that reflect the state of the diseases.
The competitive advantage of extracellular vesicles as biomarkers is based mainly on their greater stability and integrity and on their relative abundance associated with the process of tumor progression.
