Probiotic bacilli incorporation in foods: is really so easy?

Foods containing probiotic bacilli spores are becoming more and more popular because of their resistance to acidic pH, low water activity, and, most importantly, heat processes. Even though spores may engage in some functions, such as immunomodulation, the majority of the beneficial characteristics are unique to vegetative cells. As matter of fact, the development of foods fortified with spores ought to even ensure the germination of the spores along the gastrointestinal tract.

Pluripotency-Associated microRNAs in Early Vertebrate Embryos and Stem Cells.

MicroRNAs (miRNAs), small non-coding RNA molecules, regulate a wide range of critical biological processes, such as proliferation, cell cycle progression, differentiation, survival, and apoptosis, in many cell types. The regulatory functions of miRNAs in embryogenesis and stem cell properties have been extensively investigated since the early years of miRNA discovery. In this review, we will compare and discuss the impact of stem-cell-specific miRNA clusters on the maintenance and regulation of early embryonic development, pluripotency, and self-renewal of embryonic stem cells, particularly in vertebrates.
