Data manipulation? It’s normal(ization)!

Posted by on June 25th, 2019

In a previous blog, I have highlighted several ways to visualize the cell-to-cell heterogeneity from time-lapse imaging data. However, I have ignored that data is often rescaled in a way that reduces variability. For time-lapse imaging data, it is common to set the initial fluorescence intensity to 1 (or 100%). As a consequence, any changes[…]

Visualizing the heterogeneity of single cell data from time-lapse imaging

Posted by on December 12th, 2018

When we examined the kinetics of Rho GTPase activity in endothelial cells in response to receptor stimulation (Reinhard, 2017), we noticed considerable cell-to-cell heterogeneity. In the original work we published graphs with the average response, reflecting the response of the whole cell population. However, these graphs fail to show the cellular heterogeneity. What is the[…]

Accelerated Frogs: Developmental Biology meets Particle Physics

Posted by on August 20th, 2014

I previously wrote a post about the development of a 4-D X-Ray Tomography technique for imaging early Xenopus embryos. Frog embryos are opaque due to their yolky composition and this has proved a challenge for traditional optical microscopy of events in the early stages of Xenopus embryo development. However Julian Moosmann, Ralf Hofmann and Jubin[…]
