The team used multiview light-sheet and confocal microscopy to record 3D timelapse images of the establishing embryos and discovered that the multiplying cell nuclei in the cricket embryos quickly move to fill the empty area in the egg. They dont divide and move randomly through the egg; rather, its as if each nucleus can pick up the existence of other nuclei in their area and react appropriately to avoid crowding one another.Despite their focus on crickets, “we wanted to really understand the general concepts of how embryos form throughout an entire class of different insect species,” states Rycroft.I believed the best thing to do is to take the most impartial view you can, and simply observe and tape-record the real habits, and ask what patterns emerge.– Cassandra Extavour, Harvard UniversityThe scientists approached the research study with 2 hypotheses: that the nuclei may press away neighboring neighbors, and that each nucleus experiences a force that pulls it away from other nuclei and into empty area.
Now, a group of biologists and used mathematicians at Harvard University in Massachusetts have established a structure for understanding the general concepts by which cell nuclei move and organize themselves throughout the earliest phases of embryonic development to form the blastoderm. The group utilized multiview light-sheet and confocal microscopy to record 3D timelapse images of the developing embryos and discovered that the increasing cell nuclei in the cricket embryos rapidly move to fill the empty area in the egg. They dont divide and move arbitrarily through the egg; rather, its as if each nucleus can sense the existence of other nuclei in their community and react appropriately to avoid crowding one another.Despite their focus on crickets, “we wanted to truly understand the basic concepts of how embryos form across an entire class of different insect species,” states Rycroft.I believed the finest thing to do is to take the most impartial view you can, and just observe and tape-record the real behaviors, and ask what patterns emerge.– Cassandra Extavour, Harvard UniversityThe scientists approached the research study with two hypotheses: that the nuclei may press away neighboring neighbors, and that each nucleus experiences a force that pulls it away from other nuclei and into empty area.
