Mattila, J., Viitanen, A., Fabris, G., Korzelius, J & Hietakangas, V. Stem cell growth directs region-specific cell fate decisions during intestinal nutrient adaptation. Preprint in BioRxiv. (

Here we show that Intestinal Stem Cell size acts as an early fate determinant allowing regional control of intestinal cell differentiation in response to nutrition.

Viitanen, A., Gullmets, J., Morikka, J., Katajisto, P., Mattila, J & Hietakangas, V. An image analysis method for regionally defined cellular phenotyping of the Drosophila midgut. Cell Reports Methods July 30, 2021

Here we have developed a powerful tool for organ-wide quantitative analysis of the regional heterogeneity of midgut cells.

Liu, Y., Mattila, J & Hietakangas, V. Systematic Screen for Drosophila Transcriptional Regulators Phosphorylated in Response to Insulin/mTOR Pathway. G3: Genes, Genomes, Genetics August 1, 2020 vol. 10 no. 8:2843-2849

Here we have cloned a library of 850 Drosophila transcriptional regulators and used it to screen mediators of the Insulin-mTOR network. In case you are interested in using our library for screenings, do not hesitate to contact.

Mattila, J., Kokki, K., Hietakangas, V. & Boutros, M. Stem cell intrinsic hexosamine metabolism regulates intestinal adaptation to nutrient content. Dev Cell. 2018 47(1):112-121

Here we show that intestinal tissue plasticity is dependent on the glucose metabolizing hexosamine synthesis pathway. The work is previewed by Beebe & Thummel Dev Cell 2018 47(1).
