In GeneTiles the visualization and browsing of RNAseq data is greatly improved. Open source alignment and statistics programs required to map raw illumina data-files are integrated in this platform and the whole data analysis pipeline is kept open for scientific inspection and reproducibility. Differential expression of genes is shown in a 2D array of tiles. The tile color and intensity are a measure of the significance of the differential expression. When a tile is selected, the gene is loaded underneath, scaled to fit the width of the screen. In a schematic view all introns are shrunk to a fixed short length to visualize the aligned reads in a graph above the exons.
GeneTiles is published in Immunogenetics, Dec 2014

Microinjection is used for decades, however this technique has only recently been redesigned to fit the specific needs of modern high-throughput research.
Using a special grid, zebrafish eggs are aligned such that microinjection can take place at an unprecedented speed of 2500 eggs per hour.
The discovery of the possibility to infect and monitor tuberculosis progression in zebrafish is described in this paper. (open access, PLoS ONE, 2010)

Mixing polymers with a cell suspension allows for instant cell tissue creation at predefined locations in a hydrogel.
The use of these injected cell spheroids in high-throughput quantitative cancer invasion screens is described in this paper. (Biomaterials, 2012)
By automated injection of a cell suspension derived from cell culture or primary tissue material into collagen gel with a glass pulled needle, one can obtain adhered tightly packed cell spheroids within a couple of hours.
Advantages to other methods:
- Spheroid formation compatible with all cell-types
- Reproducible spheroid size (ANOVA, P=1.00) and spheroid outgrowth (ANOVA, P=0.80)
- Cell-cell and cell-matrix contacts are created directly after injection
- Spheroid postions are predetermined, ideal for high-throughput microscopy, compatible with e.g. Opera® High Content Screening System
- Compatible with all gel types and 96, 384 and 1536 titre plates
- Co-cultures possible by using a gel mixed with cells, or by injecting multiple cell-types next to each other in the same gel
