Traditional approaches to characterize stem cell differentiation are time-consuming, lengthy and invasive. Here, Raman microspectroscopy (RM) and atomic force microscopy (AFM) - both considered as non-invasive techniques - are applied to detect the biochemical and biophysical properties of trophoblast derived stem-like cells incubated up to 10 days under conditions designed to induce differentiation. Significant biochemical and biophysical differences between control cells and differentiated cells were observed. Quantitative real time PCR was also applied to analyze gene expression. The relationship between cell differentiation and associated cellular biochemical and biomechanical changes were discussed. Monitoring trophoblast cells differentiation.

Bone morphogenetic protein 4 (BMP4) is widely involved in the regulation of cell proliferation and differentiation, but its role in Recurrent Spontaneous Abortion (RSA) remains unclear. RSA is a disease that affects roughly 1-2% of partner pairs, but its pathogenesis is still unclear. In recent years, many studies have focused on the role of decidual macrophages in RSA.

The phosphatidylserine (PS) receptors AXL and TIM-1 are recognized as critical entry factors for ZIKV . However, it remains unclear if and how ZIKV regulates these receptors during infection.

Placentation disorders, including severe preeclampsia and fetal growth restriction, have their origins in early pregnancy, whereas symptoms typically present later on. To investigate the pathogenesis of these diseases, there is a need for a reliable in vitro model system of early placenta development with known pregnancy outcomes. Therefore, we optimized the generation of human induced trophoblast stem cells (iTSCs) from term umbilical cord, enabling non-invasive collection of patient-derived material immediately after birth.

Antibody-drug conjugates (ADCs) represent one of the most promising and rapidly emerging anti-cancer therapies because they combine the cytotoxic effect of the conjugate payload and the high selectivity of the monoclonal antibody, which binds a specific membrane antigen expressed by the tumor cells. In non-small cell lung cancer (NSCLC), ADCs are being investigated targeting human epidermal growth factor receptor 2 (), human epidermal growth factor receptor 3 (), trophoblast cell surface antigen 2 (), Mesenchymal-epithelial transition factor (), and carcinoembryonic antigen-related cell adhesion molecule 5 (). To date, Trastuzumab deruxtecan is the only ADC that has been approved by the FDA for the treatment of patients with NSCLC, but several ongoing studies, both using ADCs as monotherapy and combined with other therapies, are investigating the efficacy of new ADCs.

Background: Adverse pregnancies outcomes present a clinical dilemma in Perinatal medicine. This is partly due to lack of accuracy of current biomarkers to predict high-risk pregnancies at an earlier stage. The placental alkaline phosphatase (PLAP) carrying extracellular vesicles (EVs), and their cargo have been reported as a source of biomarkers for placental health and an indication of pre-eclampsia progression.
