Biofabrication of Tissue Engineered Constructs

Ongoing
OCT imaging was assessed using a model scaffold-cell system consisting of a polysaccharide-based hydrogel seeded with human Jurkat cells. Four test systems were used: hydrogel seeded with live cells, hydrogel seeded with heat-shocked or fixed dead cells and hydrogel without any cells. Time series

Bioimaging

Completed
Imaging and image analysis are used ubiquitously in biological and biomedical research. One of the great advantages of imaging is its intuitive information content; much can be learned from just a glance at the data. On the other hand, these data generally contain a very large amount of untapped

Gene Delivery Systems

Ongoing
Viral Vectors Viral vectors are a critical tool for delivering DNA or RNA into patient’s cells. Common viral vectors for gene therapy include adenovirus, lentivirus, and adeno associated virus. Administration of viral vectors can occur in vivo or ex vivo , such as for adeno associated virus or

Live Cell Imaging of Induced Pluripotent Stem Cell Populations

Ongoing
As part of our program in Cell Biology , our live cell image program supports the advancement of induced pluripotent stem cell (iPSC) technology in three ways: 1) Identification of process control measurements: A critical component to the translation of iPSCs into therapeutic applications is to

Measurement Assurance for Quantitative Cell Imaging by Optical Microscopy

Ongoing
Light microscopy is unparalleled as a quantitative technique for studying cell biology, but assuring that the results of measurements and analyses are accurate, repeatable and sharable is challenging. Here we provide information on reference materials, protocols and approaches for evaluating the

Next Generation Metrics for Cell-Based Therapies and Regenerative Medicines
