The natural capacity of simple organisms to survive in a dehydrated state has long been exploited by man, with lyophylization the method of choice for the long term storage of bacterial and yeast cells. More recently, attempts have been made to apply

Since the birth of the first baby conceived by in vitro fertilization (IVF), assisted reproductive technologies (ART) have been constantly evolving to accomodate needs of a growing number of infertile couples. Rapidly developing ART procedures are di

Significance Lipid droplets (LDs) are stored in the embryo throughout the preimplantation development. Yet, the role of LDs in the embryo remains unknown. Embryonic diapause (ED) is a temporary arrest of an embryo when it waits for the uterine recept

Assisted Reproductive Technologies (ART) allowed the births of >8 million babies worldwide. Even if ART children are healthy at birth, several studies reported that ART may cause changes in foetal programming, leading to an increased predisposition t

Postponement of fatherhood is growing worldwide due to socio-economic factors. The choice to conceive the first child above the age of 35 years is often associated with reduced fertility and poor pregnancy outcome. As widely known, several factors (e

Aging Cell
In somatic cells/tissues, methylation of ribosomal DNA (rDNA) increases with age and age‐related pathologies, which has a direct impact on the regulation of nucleolar activity and cellular metabolism. Here, we used bisulfite pyrosequencing and show

Reproductive cells are a very special kind of material for the analysis. Depending on the species, their dimensions allow for the application of mass spectrometry imaging-based techniques to receive a reasonable data for interpretation of their condi
