AbstractRecent advances in the directed differentiation of human pluripotent stem cells to kidney brings with it the prospect of drug screening and disease modelling using patient-derived stem cell lines. Development of such an approach for high content screening will require substantial quality control and improvements in throughput. Here we demonstrate the use of the NovoGen MMX 3D bioprinter for the generation of highly reproducible kidney organoids from as few as 4,000 cells. Histological and immunohistochemical analyses confirmed the presence of renal epithelium, glomeruli, stroma and endothelium, while single cell RNAseq revealed equivalence to the cell clusters present within previously described organoids. The process is highly reproducible, rapid and transferable between cell lines, including genetically engineered reporter lines. We also demonstrate the capacity to bioprint organoids in a 96-well format and screen for response to doxorubicin toxicity as a proof of concept for high content compound screening.

Adverse Pregnancy

Among patients with psoriasis, approximately 50% are women and almost 75 % of them are under the age of 40 years. Thus, most women with psoriasis have childbearing potential. When pregnancy occurs in 22 % of patients, the activity of psoriasis persists, characteristic of the course before pregnancy, in 23 % of women, the course of the disease worsens. The article provides up-to-date data on the management of pregnant patients with psoriasis. To improve pregnancy outcomes in patients with psoriasis, it is important to prevent exacerbation of the disease. The choice of drug therapy in this case is based on an assessment of the ratio of the risk of undesirable effects of the drugs on the developing fetus and the risk of the development of exacerbation of psoriasis, which can cause an adverse pregnancy outcome. Despite the fact that the available clinical experience of using genetically engineered drugs is still limited, with a certain degree of confidence we can say that there is no increase in the risk of adverse pregnancy outcomes associated with therapy with certolizumab pegol.

AbstractLuminescent CdSe-ZnS core-shell quantum dot (QD) bioconjugates were used as energy donors in fluorescent resonance energy transfer (FRET) binding assays. The QDs were coated with saturating amounts of genetically engineered maltose binding protein (MBP) using a noncovalent immobilization process, and Cy3 organic dyes covalently attached at a specific sequence to MBP were used as energy acceptor molecules. Energy transfer efficiency was measured as a function of the MBP-Cy3/QD molar ratio for two different donor fluorescence emissions (different QD core sizes). Apparent donor-acceptor distances were determined from these FRET studies, and the measured distances are consistent with QD-protein conjugate dimensions previously determined from structural studies.

Differential Gene

Differential gene expression analysis of multiple datasets, in mice and in men revealed that transcripts of the olfactomedin-like family are differentially expressed in metastases, both in patients with breast cancer and in genetically engineered mouse models of breast cancer. The expression of olfactomedin-like genes was perturbed in metastases to the bone, brain and the lung, suggesting that these molecules function in the metastatic process rather than having tissue-specific associations with the site of dissemination. The olfactomedin-like family may play a role in the progression of breast cancer from frank tumor to colonization of distant organ sites.
