Ongoing projects*

Multicolor cell labeling for solving the clonal structure of murine embryo neural crest

Department of Medical Bioschemistry and Biophysics, Karolinska Institutet

In this project, we will experimentally target clonal structures of the cranial neural crest cells and will study their reparative plasticity as well as underlying signaling mechanisms that can be considered as new therapeutic targets. At the single cell and clonal levels, we will systematically explore the spectrum of signals integrating the growing oral and craniofacial complex. 

The effect of temperature on the bumblebee brain

Department of Zoology, Stockholm University

The aim of the project is to understand if and how the information carried by neurons in the bumblebee brain is affected by temperature. The findings will have consequences for understanding how increasing environmental temperatures, such as those that are occurring as a result of climate change, will affect the function of insect nervous systems and behavior.
Evaluation of autofluorescence life-time imaging to observe differences in biological samples

Imaging Candida albicans infection in the mouse kidney

Department of Molecular Biosciences, Stockholm University

C. albicans cells constitutively expressing mCherry (red) were stained with FITC and analysed in a systemic murine model of infection and visualized colonizing a kidney. Green, FITC associated with mother cells (yeast form); Red, mCherry expression in growing daughter cells; note hyphal morphology; Teal, NAD(P)H autofluorescence. (Unpublished data, M. Ward, F.G.S. Silao, C. Peuckert and P.O. Ljungdahl).
