Research activity

His research is documented by 196 publications in scientific Journals and Books and partecipations to congresses of which 99 in refereed ISI Journals, including Nature, Nature Genetics, Nature Communications, PNAS, Science and PLOS Genetics. The results published in Nature are included in Developmental Biology text-books. To the work demonstrating the reprogramming capacity of mouse oocytes, Nature has dedicated the cover.

His research is focused on mammalian reproduction and preimplantation development. Specifically, he is now interested in the origin of the oocyte’s developmental competence and how the concept of developmental competence bridges with that of pluripotency. A further line of research ongoing in his laboratory is concerned with the study of embryonic stem cell differentiation into cardiomyocytes, the latter as a differentiation platform for toxicological studies.

Main research lines:

  1. Gamete differentiation

Oogenesis. Functional studies of the mouse oocyte’s chromatin organisation and gene expression during folliculogenesis have allowed the identification of the developmentally competent female gametes. Employing cellular and systems biology approaches, our goal is to unravel the molecular signature that characterises the oocyte developmental competence (toti/pluripotency). Most recently we identified a subgroup of cumulus cells that, when used for the preparation of a feeder layer, confer meiotic and developmental competence to the maturing oocyte. The lab is now trying the identification of the paracrine factors released by these cumulus cells.
With a comparative view, the studies on oogenesis are extended to other mammals like the shrew Sorex araneus and the armadillo Chetophractus villosus, one of the earlier placental offshoots.

Spermatogenesis. We have described the cycle of the seminiferous epithelium of several mammals (rodents, insectivores and Xenarthra) and the influence that structural rearrangements of the karyotype have on the male gametogenesis and thus on the evolutionary processes that lead to speciation. We have also studied the molecular bases of Robertsonian chromosome translocations, identifying the involvement of the satDNA fraction in the process that leads to acrocentric chromosomes fusion and to the formation of metacentrics. The work is now finalised to the understanding of the mechanisms that cause meiotic arrest in the presence of chromosome rearrangements.

2. Preimplantation development

His studies have defined some of the steps and molecular mechanisms that regulate the first week in the life of the mammalian embryo, such as the remodelling of the chromatin organisation, the expression of zygotic genes and the inactivation of the X chromosome. This work has also led to demonstrate the capacity of the mouse oocyte to reprogram the nucleus of a terminally differentiated somatic cell. The work on oogenesis has identified a gene network involved in the acquisition of the oocyte developmental competence; network that is shared with pluripotent embryonic stem cells. Using a systems biology approach, the lab is now trying to describe the origin of this gene network during folliculogenesis and how it is modulated during preimplantation development, when pluripotency is built up.

3. Embryonic stem cells differentiation

Mouse embryonic stem cells (ESCs) have been used as an in vitro model of mesoderm differentiation to obtain megakaryocytes. This work has described, for the first time, the transcriptional and proteomic signature of these cells, highlighting their immaturity when compared to fetal megakaryocytes. Also, we have developed an ESC-differentiation platform to detect the effects that chemical (e.g., dioxin) or physical (e.g., ionising radiations) agents during ESCs differentiation into cardiomyocytes. Using this platform, the work is now aimed at unravelling the signalling mechanisms of stem cell cardiac differentiation dysregulated by arsenic, an environmental contaminant and a therapeutic agent.
