The public may view the reports by going to, This undated combination of microscope images provided by Monash University in March 2021 shows different "iBlastoids" (embryo-like structures) stained to highlight different cell types. Scientists previously generated similar structures of mouse cells in a lab, but this is the first time they have been made from human cells. Should restrictions apply?”. The new models correspond to about three to 10 days after fertilization, Wu said. “The blastoids are less efficient in terms of generating structures mimicking later stage human embryos,” said Wu, whose team stopped growing the structure in a culture after four days.
