The goal of this long-term program is to promote the development of non-invasive diagnostic devices for the clinical care. Clinical diagnostics has entered a new era of miniaturization. Functional micro-laboratories have been developed on a microchip platform performing a broad range of analytical assays. Special interest is focused on devices for point-of-care analysis and life science (cell analysis), with future prospects towards personalized medicine.

One of our main scientific orientations is the non-invasive search for the molecular viability markers of in vitro fertilized embryos using the culture medium. In addition to the currently used morphological embryo viability assessment new parameters are required since embryos selected for transfer using visual diagnosis does not lead to successful delivery in the expected rate. The theoretical background of the patented technology is the measurement of a quantitative protein marker allowing the selection of the morphologically fit, however, functionally non-viable embryos. Our further goal is to develop a diagnostic POCT tool for clinical purposes. Also, the group focuses on structural and functional analysis of the nucleic acid content isolated from spent human embryonic culture media. Circulating cell-free DNA with both nuclear or mitochondrial origin and exosomal gene expression regulatory miRNAs get into the embryonic culture media either by active secretion or apoptotic destruction. Recognition of these molecular fractions in the culture media has generated an interest for their potential use as markers for genetic disorders. On-going projects involve the following research goals: 

•          to identify human aneuploidy-specific biomarkers by NGS sequencing techniques

•          viability prediction of the early embryo by qualitative and quantitative analysis of the genes involved in embryo development and metabolism (Zfp57, Dppa5a, Sirturin1, Sp1, Gata1, Gata2, Fgfr1, Glut3, Racgap1, Idb2 and  Per3 and the Clk)

•          Polymerase γ A gene, a major influencing factor of the embryonic mtDNA replication.

•          structural and quantitative analysis of exosomal mRNA and miRNA fractions       

In the case of serious systematic inflammation processes (sepsis) the use of personalized medicine is of vital importance to reliably evaluate the severity of the disease using biomarkers. Actin and gelsolin present in serum, the elevated level of orosomucoid in urine, or the quantification of serum total and free cortisol are all correlating with the severity of the patient’s condition. We also proved that the prognosis of the sepsis can be estimated by monitoring cortisol level during hospitalization.

In tumor diseases the in vitro invasivity of circulating tumor cells correlates with the severity of the disease and the metastatic potential of the tumor. The use of PoCT devices to detect and quantify circulating tumor cells helps to construct a personalized therapeutic strategy. Also the technology of 3D cell culturing is a potential model of cell-cell interactions, allowing the culturing of tumorous and healthy cells in the same matrix modeling in vivo circumstances. The technology is capable of examining the behavior and chemotherapic sensitivity of tumorous cells under circumstances similar to the human body.
