REVIEW
Antonio Capalbo, Laura Rienzi
Defining the actual incidence and prevalence of mosaicism in human blastocysts still remains a difficult task. The small amount of evidence generated by animal and human studies does not support the existence of mechanisms involved in developmental arrest, clonal depletion, or aneuploidy rescue for abnormal cells in euploid/aneuploid embryos during preimplantation development. However, studies in humans are mainly descriptive and lack functional evidence. Understanding the biological mechanisms that beset preimplantation differentiation holds the potential to reveal the role of aneuploidies and gene dosage imbalances in cell fate decision, providing important clues on the origin and evolution of embryonic mosaicism...

REVIEW
Maria Vera-Rodriguez, Carmen Rubio
Modern technologies applied to the field of preimplantation genetic diagnosis for aneuploidy screening (PGD-A) have improved the ability to identify the presence of mosaicism. Consequently, new questions can now be addressed regarding the potential impact of embryo mosaicism on diagnosis accuracy and the feasibility of considering mosaic embryos for transfer. The frequency of chromosomal mosaicism in products of conception (POCs) of early miscarriages has been reported to be low. Mosaic embryos with an aneuploid inner cell mass are typically lost during the first trimester owing to spontaneous miscarriages...

Embryonic mosaicism, the presence of more than one distinct cell line within an embryo, has recently become the focus of growing attention and controversy in the context of preimplantation genetic screening (PGS). To evaluate the extent of mosaic aneuploidy in clinical practice and to gain insight on the practices and views regarding this issue, we conducted a survey using a prospective, 20-item Web-based questionnaire with questions related to practices and views regarding mosaicism in PGS. A total of 102 in vitro fertilization (IVF) units from 32 countries that performed 108,900 IVF cycles annually responded to the survey...

REVIEW
Santiago Munné, Dagan Wells
A significant proportion of human preimplantation embryos produced during the course of in vitro fertilization (IVF) treatments contain two or more cytogenetically distinct cell lines. This phenomenon, known as chromosomal mosaicism, can involve the presence of cells with different types of aneuploidy in the absence of any normal cells or a mixture of euploid and abnormal cells. Although a high prevalence of mosaicism at the cleavage and blastocyst stages has been appreciated for two decades, the precise frequency of the phenomenon and its consequences for embryo viability have been difficult to quantify...
