MDCell is hosting cooperation projects between the Max Delbrück Center for Molecular Medicine Berlin (MDC) and external partners. Such partners may be private companies interested in technologies developed at the MDC.
MDCell is fueled by discoveries and inventions developed in the research groups of renowned scientists in the gene and cell therapy field: Dr. Zsuzsanna Izsvák and Prof. Wolfgang Uckert.
MDCell’s focus is on the non-viral gene transfer based on the Sleeping Beauty 100x transposon system for the development of cell- and gene-therapies.
Scientific advisors of MDCell are Dr. Zsuzsanna Izsvak (inventor of the Sleeping Beauty 100x system) and Prof. Dr. Wolfgang Uckert (expert in T cell therapies). Long standing expertise in the field of cell and gene therapies drive the development of MDCell.
MDCell is headed by Dr. Jan Pille.
The MDCell is supported by a Helmholtz Innovation Lab grant.

This is a DNA/RNA-based gene engineering tool that does not require the generation of viral vectors. Thus, it provides a great opportunity to facilitate cell engineering for research and clinical use.
The SB system consists of two components: the transposase enzyme SB100x and the transposon vector pT4. For genomic integration, the SB100x binds to inverted repeats (IR) of pT4 that flank the transgene cassette and paste the transgene into the genome of a host cell. This process is random and SB100x has no preference to integrate in transcriptionally active or oncogenic gene regions.
The MDCell team and the group of Prof. Dr. Wolfgang Uckert was able to improve the gene-transfer system especially fir transfer into primary human T cells by using in vitro transcribed RNA (IVT-RNA) for the transfer of SB100x and a minicircle DNA format for the transfer of pT4 (see Figure 1).
MDCell and the group of Prof. Dr. Wolfgang Uckert applied the improved SB100x/pT4 gene transfer system in primary human T cells. This method enables stable transfection rates of TCRs or CARs of 50% upon a single modification step while maintaining a high survival rate and full functionality of the T cells (see Figure 2).

The MDCell is supported by experts from theand by the qualified team of technology transfer partner (contact Michael Karle:
GmbH & Co. KG is a biopharmaceutical company founded in 2000 in Bielefeld, Germany. It has since developed into an international company. PlasmidFactory produces plasmids and minicircles according to client’s individual requirements in modern laboratories with highest quality. In addition to custom manufacturing of plasmid and minicircle DNA, PlasmidFactory focuses its research and development efforts on its core competencies in the production, analysis, application, and storage of DNA.
PlasmidFactory´s minicircle technology, resulting in a pure, supercoiled monomeric minicircle, provides the basis for an optimized Sleeping Beauty transposon system, using minicircle mT4 vector and SB100X transposase-encoding RNA, that facilitates the rapid non-viral generation of engineered T cells for immunotherapy.
The MDCell Helmholtz Innovation Lab and NAVAN Technologies, Inc. are actively collaborating with the shared mission of combining the virus-free, reliable and safe Sleeping Beauty transposon system with the fast, effective and gentle intracellular delivery technique of Nano-Straws to reprogram human T-cells. The purpose of this collaboration is to accelerate the development of T-cell immunotherapies for the treatment of cancers and other incurable diseases.
For this, the patient’s most potent immune cells - the T cells – are genetically engineered with a receptor (TCR) enabling them to detect and eradicate cancer cells. Captain T Cell has developed a unique TCR and epitope discovery platform that is the only available technology that generates TCRs for immunodominant cancer targets and thus, more effective TCRs. Captain T Cell is currently developing lead candidate TCRs for clinical application.
Captain T Cell won the world’s largest life science business plan competition OneStart (London, 2016) and the jury award for best spin-off idea at the BioVaria conference (Munich, 2017).
