Pluripotency and X chromosome dynamics revealed in pig pre-gastrulating embryos by single cell analysis (2019)
Journal Article
Ramos-Ibeas, P., Sang, F., Zhu, Q., Wang, W. W., Withey, S., Klisch, D., …Alberio, R. (2019). Pluripotency and X chromosome dynamics revealed in pig pre-gastrulating embryos by single cell analysis. Nature Communications, 10, doi:10.1038/s41467-019-08387-8

High-resolution molecular programmes delineating the cellular foundations of mammalian embryogenesis have emerged recently. Similar analysis of human embryos is limited to pre-implantation stages, since early post-implantation embryos are largely ina... Read More

A lexicon of DNA modifications: their roles in embryo development and the germline (2018)
Journal Article
Zhu, Q., Stöger, R., & Alberio, R. (2018). A lexicon of DNA modifications: their roles in embryo development and the germline. Frontiers in Cell and Developmental Biology, 6, doi:10.3389/fcell.2018.00024. ISSN 2296-634X

5-methylcytosine (5mC) on CpG dinucleotides has been viewed as the major epigenetic modification in eukaryotes for a long time. Apart from 5mC, additional DNA modifications have been discovered in eukaryotic genomes. Many of these modifications are t... Read More

Cancer reversion with oocyte extracts is mediated by cell cycle arrest and induction of tumour dormancy (2018)
Journal Article
Saad, N., Alberio, R., Johnson, A. D., Emes, R. D., Giles, T. C., Clarke, P., …Allegrucci, C. (2018). Cancer reversion with oocyte extracts is mediated by cell cycle arrest and induction of tumour dormancy. Oncotarget, 9(22), doi:10.18632/oncotarget.24664

Inducing stable control of tumour growth by tumour reversion is an alternative approach to cancer treatment when eradication of the disease cannot be achieved. The process requires re-establishment of normal control mechanisms that are lost in canc... Read More

Transcriptional and epigenetic control of cell fate decisions in early embryos (2017)
Journal Article
Alberio, R. (2017). Transcriptional and epigenetic control of cell fate decisions in early embryos. Reproduction, Fertility and Development, 30(1), doi:10.1071/RD17403. ISSN 1031-3613

Mammalian embryo development is characterized by regulative mechanisms of lineage segregation and cell specification. A combination of carefully orchestrated gene expression networks, signalling pathways and epigenetic marks define specific developme... Read More

Principles of early human development and germ cell program from conserved model systems (2017)
Journal Article
Kobayashi, T., Zhang, H., Tang, W., Irie, N., Withey, S., Klisch, D., …Surani, M. (2017). Principles of early human development and germ cell program from conserved model systems. Nature, 546, doi:10.1038/nature22812

Human primordial germ cells (hPGCs), the precursors of sperm and eggs, originate during week 2-3 of early postimplantation development(1). Using in vitro models of hPGC induction(2-4), recent studies suggest striking mechanistic differences in specif... Read More

Epigenetics and developmental programming of welfare and production traits in farm animals (2016)
Journal Article
Sinclair, K. D., Rutherford, K., Wallace, J., Brameld, J., Stöger, R., Alberio, R., …Dwyer, C. (in press). Epigenetics and developmental programming of welfare and production traits in farm animals. Reproduction, Fertility and Development, 28(10), doi:10.1071/RD16102. ISSN 1031-3613

The concept that postnatal health and development can be influenced by events that occur in utero originated from epidemiological studies in humans supported by numerous mechanistic (including epigenetic) studies in a variety of model species. Referr... Read More

Primordial germ cells: the first cell lineage or the last cells standing? (2015)
Journal Article
Johnson, A. D., & Alberio, R. (in press). Primordial germ cells: the first cell lineage or the last cells standing?. Development, 142, doi:10.1242/dev.113993. ISSN 0950-1991

Embryos of many animal models express germ line determinants that suppress transcription and mediate early germ line commitment, which occurs before the somatic cell lineages are established. However, not all animals segregate their germ line in this... Read More

Actin depolymerization is associated with meiotic acceleration in cycloheximide-treated ovine oocytes (2015)
Journal Article
German, S. D., Lee, J., Campbell, K. H., Sweetman, D., & Alberio, R. (in press). Actin depolymerization is associated with meiotic acceleration in cycloheximide-treated ovine oocytes. Biology of Reproduction, 92(4), doi:10.1095/biolreprod.114.122341. ISSN 0006-3363

Oocytes treated with the protein synthesis inhibitor cycloheximide (CHX) arrest at the germinal vesicle (GV) stage and undergo accelerated GV breakdown (GVBD) after CHX is removed. However, little is known about the underlying mechanism of accelerate... Read More

Ovine induced pluripotent stem cells are resistant to reprogramming after nuclear transfer (2015)
Journal Article
German, S. D., Campbell, K. H., Thornton, E., McLachlan, G., Sweetman, D., & Alberio, R. (2015). Ovine induced pluripotent stem cells are resistant to reprogramming after nuclear transfer. Cellular Reprogramming, 17(1), doi:10.1089/cell.2014.0071. ISSN 2152-4971

Induced pluripotent stem cells (iPSCs) share similar characteristics of indefinite in vitro growth with embryonic stem cells (ESCs) and may therefore serve as a useful tool for the targeted genetic modification of farm animals via nuclear transfer (N... Read More

Paracrine effects of embryo-derived FGF4 and BMP4 during pig trophoblast elongation (2014)
Journal Article
Valdez Magana, G., Rodríguez, A., Zhang, H., Webb, R., & Alberio, R. (2014). Paracrine effects of embryo-derived FGF4 and BMP4 during pig trophoblast elongation. Developmental Biology, 387(1), doi:10.1016/j.ydbio.2014.01.008. ISSN 0012-1606

The crosstalk between the epiblast and the trophoblast is critical in supporting the early stages of conceptus development. FGF4 and BMP4 are inductive signals that participate in the communication between the epiblast and the extraembryonic ectoderm... Read More
