Existing analytical techniques are being improved or applied in new ways to profile the tissue microenvironment (TME) to better understand the role of cells in disease research. Fully understanding the complex interactions between cells of many different types and functions is often slowed by the intense data analysis required. Multiplexed Ion Beam Imaging (MIBI) has been developed to simultaneously characterize 50+ cell types and their functions within the TME with a subcellular spatial resolution, but this results in complex data sets that are challenging to qualitatively analyze.

Background: Type 1 diabetes, an autoimmune disorder leading to the destruction of pancreatic β-cells, requires lifelong insulin therapy. Islet transplantation offers a promising solution but faces challenges such as limited availability and the need for immunosuppression. Induced pluripotent stem cells (iPSCs) provide a potential alternative source of functional β-cells and have the capability for large-scale production.

Article Synopsis
  • The study explores the use of suspension culturing in vertical wheel bioreactors to optimize stem cell expansion, addressing challenges in scalability and cell aggregation stability.
  • Various media additives, including PEG and Heparin, were tested to improve pluripotency, expansion rate, and reduce aggregate fusion, resulting in a 40% shorter doubling time compared to traditional methods.
  • The optimized solution maintained high pluripotency markers in two different cell lines, demonstrating that careful formulation and control of culture conditions can enhance stem cell growth and stability.

Background And Aims: Anxiety plays a distressing role in cardiothoracic operations. It may trigger hemodynamic instability, increased morbidity, and very crucially, postoperative pain and analgesic use. Our aim is to look at the association between anxiety, postoperative pain, and analgesic use.
