Abstract/OtherAbstract:
Due to the risks to the foetus with invasive prenatal diagnosis, non-invasive prenatal diagnosis (NIPD) is gaining tremendous interest but no reliable method that can be widely used has been developed to date. Manipulation of foetal cells and foetal cell-free genetic material in the maternal blood are two promising approaches being researched. The manipulation of foetal cells in the maternal circulation is more popular as it can provide complete genetic information of the foetus particularly the diagnosis of aneuploidies. However, the foetal cell numbers in the maternal circulation are small and their enrichment and ex vivo culture remain two major challenges for NIPD. Primitive foetal erythroblasts (pFEs) have been considered as a good potential candidate for early first trimester NIPD but their nature, properties and manipulation to provide adequate cell numbers remain a challenging task and several approaches need to be meticulously evaluated. In this review we describe the current status of NIPD and suggest some novel approaches in manipulating pFEs for future clinical application of NIPD. These novel approaches include (1) understanding the pFE enucleation process, (2) enriching pFE numbers by individual pick-up of pFEs from maternal blood using micromanipulation and microdroplet culture, (3) expansion of pFEs using mitogens and (4) decondensation of the pFE nucleus with histone deacetylase (HDAC) inhibitors followed by reprogramming using gene delivery protocols with/without small reprogramming molecules to improve reprogrammed pFE proliferation rates for successful NIPD.
