Mogrify has launched a platform to model the epigenetic state of a cell and predict switches important for cell identity, cell maintenance, directed differentiation and cell conversion.
EpiMOGRIFY aims to enable the identification of the optimal culture conditions required to maintain cells in chemically defined media. This can be applied in cGMP manufacture and enhances directed differentiation or cell conversion to support the development of scalable off-the-shelf therapies for diseases with unmet clinical need.
EpiMOGRIFY combines gene-regulatory information with a model of a cell’s epigenetic landscape and leverages changes in the level of DNA-histone methylation (H3K4me3 modifications). The platform uses data from more than 100 human cell/tissue types (available via the ENCODE and Epigenome Roadmap consortia) to define culture conditions that can maintain the cell identity or induce cell conversion.
The EpiMOGRIFY platform and patent were co-developed and are co-owned by Duke-NUS (Enrico Pettreto, Associate Professor and Owen Rackham, Assistant Professor at Duke-NUS Medical School), Monash University (Jose Polo, Professor at Monash University) and Mogrify. The research underpinning the platform has recently been published in Cell Systems (Kamaraj et al., 2020).
Owen Rackham, PhD, Assistant Professor at Duke-NUS Medical School, Singapore, and Co-founder and CTO, Mogrify, said: “Building on our development of the Mogrify technology to identify transcriptomic switches for cell conversion, this new technology published in Cell Systems adds an important layer of epigenetic specificity in our continuous search to drive cell identity with an increasing level of control. The ability to systematically identify the optimal culture conditions, closely mimicking the in vivo microenvironment, will enable scientists to convert and maintain any cell type more efficiently and with even greater accuracy.”
The predictive power of EpiMOGRIFY has been validated in two ways: cell maintenance and differentiation. EpiMOGRIFY-predicted factors are able to maintain astrocytes and cardiomyocytes in vitro in chemically defined media and promote the generation of astrocytes and cardiomyocytes from neural progenitors and embryonic stem cells, respectively. In both cell maintenance and differentiation, Mogrify says, EpiMOGRIFY defined conditions performed as well or better in all cases when compared to existing undefined conditions, significantly increasing cell growth and survival, as well as resulting in a higher differentiation efficiency.
