All bacteria exist as single cells at some point in their lives – except for one kind, known as multicellular magnetotactic ...

However, to create ES cell lines, it is necessary to destroy preimplantation embryos at the blastocyst stage of 100–200 cells. Many people believe that life begins at conception and that ...

This might be an evolutionary feature that influences the developmental fate of the blastocysts," explains Kroneis, who is ...

How alterations in cell metabolism translate into specific developmental gene programs remains a major question. This study ...

Early embryonic cell polarity and lineage differentiation, which are vital to implantation, and continued embryonic growth climax with the onset of blastocyst formation. These processes are ...

After 4 days of this development in the fallopian tube, the formed cellular mass of the morula migrates to enter the uterus with formation the blastocyst (polarized cells with accumulating fluid ...
