Research description

Pluripotency, Embryonic Stem Cells and Regenerative Medicine

The Lanner lab aims to:

1. Uncover the fundamental principles underlying how the first cell types and pluripotency is established in the early human embryo.

2. Develop embryonic stem cell based strategies. We have establish a first clinically compliant good manufacturing practice (GMP) grade human embryonic stem cell line, KARO1. KARO1 is now available for collaborators in the stage of clinical translation. We are currently looking into developing genetically engineered versions to combat transplantation rejection. 

3. Treatment of Diabetes. We are actively working to establish methodology both to efficiently produce glucose responsive beta cells and evaluate the optimal way to deliver these to the patient.

4. Treatment of age-related macula degeneration (AMD). We have enter a collaborative agreement with St. Erik Eye Hospital and Novo Nordisk A/S to manufacture hESC-RPE cells according to our developed protocol and conduct a clinical aiming to treat AMD. We continue to advance related methodologies and increase our fundamental knowledge of how the different cell types of the retina are established during embryogenesis and in vitro.

Together with Mona Hedenskog and Heather Main we are working intensively to derive clinically compliant ESCs which we will be usefull for academic and industial efforts within stem cell based regenerative medicin. Our first GMP grade line is derived, please contact us if interested in such cell line.
