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. Establish a good manufacturing practice (GMP) bank of clinically compliant high quality embryonic stem cells (ESCs).
3. Explore treatment of age-related macula degeneration using ESC derived retinal pigmented epithelial cells.
ESCs isolated from the human blastocyst can be propagated indefinitely and directed into any cell type of the adult human, offering great potential for regenerative medicine to replace lost or damaged tissues. The knowledge of how these pluripotent cells are established and controlled in vivo is generated primarily in animal modes such as the mouse while our knowledge of the same process in the human is rudimentary and key differences are emerging. We will explore these issues through single cell mRNA sequencing, pioneering genetic technologies and functional assays in human blastocysts. This fundamental knowledge will also be important for our understanding of infertility, a problem affecting 10-15% of all couples in our society.
We have established an efficient differentiation methodology of ESCs into clinically relevant cell types. However, before these safely can become clinical practice, additional hurdles must be overcome such as GMP production and immune matching of cells and patients. By establishing the KI Stem Cell Bank we hope to resolve these issues and facilitate efforts to move stem cell based regenerative medicine into the clinic. Finally, we will specifically aim to initiate trials based on ESC in treatment of macular degeneration, the major cause of blindness in our elderly population.
