Human embryonic (hESCs) and induced pluripotent stem cell (hiPSCs) facility
Vascular Organoids
Retinal Organoids
Vascular organoid generated from vascular smooth muscle cells (red) and endothelial cells (green) both differentiated from human embryonic stem cells. Nuclei are shown in blue. Murphy-Fotsis lab |
We have established a facility which handles hESCs and hiPSCs. These cells are used for basic research and also as disease models. Projects that the stem cell facility can perform in collaboration and/or under subcontracting include:
Generation of patient specific human induced pluripotent stem cells
CRISPR genome editing of hESCS and hiPSCs
Expression of genes of interest in hESCs and hiPSCs
Differentiation of hESCs/hiPSCs to endothelial and mural cells
Targeted differentiation of patient derived hiPSCs
Formation of gastruloids
Generation of Vascular organoids
Generation of Retinal and other organoids
Vascularisation of organoids
Generation of anterior cruciate ligament
Drug and small molecule semi-high throughput screening of patient derived hiPSCs
Toxicology in human pluripotent and differentiated cell types
Endothelial barrier models to assess drug availability
Advanced imaging techniques
The facility harbours 2 incubators dedicated for work with these cell types, a dissection hood and a biosafety flow cabinet. A stereo microscope for isolation of clones and a Zeiss microscope for visualization and imaging are also available. Stem cells are handled separately from other cell types and liquid nitrogen storage containers harbouring cell stocks are also dedicated to stem cells to avoid potential contamination.
