Identification of novel cell surface markers for cell therapy applications
Despite the progress in safety and efficacy of cell replacement therapy with pluripotent stem cells (PSCs), the presence of residual undifferentiated stem cells or proliferating progenitor cells with rostral identity remains a major challenge. Using a proteomics approach, we recently identify new set of cell surface markers on dopaminergic progenitor cells (CNTN2) and cardiac progenitor cells (ALCAM), which allow isolation of a more beneficial population for cell replacement therapy. Transplantation of human-PSC-derived purified CNTN2+ progenitors enhanced dopamine release from transplanted cells in the host brain and alleviated Parkinson’s disease-related phenotypes in animal models (Fathi et al. 2018, Molecular Cellular Proteomics). Transplantation of ALCAM+ progenitors enhances tissue recovery, restores cardiac function, and improves angiogenesis through activation of AKT-MAPK signaling in a rat model of myocardial infarction, based on cardiac MRI and histology (Ghazizadeh et al., .2018, Stem Cell Reports).
We are currently working on identification of novel cell surface markers of different progenitor cells for cell therapy applications.
Human Y Chromosome Proteome Project
We have developed the mid- and long-term research plant for the project (Jangravi et al., 2013) and attempted to identify several missing proteins of Y chromosome and their possible functions in male infertility (Ahmadi Rastegar et al., 2015), prostate cancer (Jangravi et al., 2015), neural differentiation (Vakilian et al., 2015) and cardiac differentiation of human embryonic stem cells (Meyfour et al., 2017). We could also identify several novel isoforms of Y chromosome genes.
Recently, We conducted a deep subcellular proteomics analysis of hESCs to identify the nuclear, cytoplasmic, and membrane proteins in hESCs and to mine missing membrane proteins in the very early cell status. We generated the largest data set with confident identification of 11970 unique proteins including the most-comprehensive description of 6138 annotated membrane proteins in hESCs. Following the HPP guideline, we also identified 26 gold and 87 silver missing proteins (Weldemariam et al., 2018). Our proteome map of hESCs may provide a rich resource not only for the identification of MPs in the human proteome but also for the investigation on self-renewal and differentiation of hESC.
We are now generating hESC lines in which Y chromosome genes are knocked-out or overexpressed. Due to the capacity of hESCs to differentiate to all lineages, this cell lines will allow us to analyze the function of Y chromosome genes during ectoderm, endoderm and mesoderm differentiation. A combined cellular, molecular and omics analysis of these cell lines during differentiate will give us valuable insight into the functional of Y chromosome genes at cellular levels in very important cells and pathways.
I have been using recombinant protein technology to produce growth factors required for hESC maintenance and differentiation leading to two spin-off companies: Royan Biotech, dedicated to growth factor production, and Royesh GeneAsa Teb, dedicated to generating cell lines producing pharmaceutical recombinant antibodies.
