Organ Architects: The Remarkable Cells Shaping Our Development

Tooth epithelium (cell surface area; yellow) and mesenchyme (cell surface; magenta). Multiplying cells (cyan) broaden the tissue, producing a mechanical pressure at the tissue center that drives the formation of the primary tooth signaling center or organizer, the enamel knot. Fortunately, like cell phone towers in a city, embryos include special cells in specific locations, understood as organizers, that send signals to other cells and help them organize to develop our complex organs.Some of these signals are particles sent out from the organizer, a privileged signaling.”Our work shows that both mechanical pressure and molecular signaling play a role in organ development,” said Ophir Klein, MD, PhD, Executive Director of Cedars-Sinai Guerin Childrens, where he is also the David and Meredith Kaplan Distinguished Chair in Childrens Health, and co-corresponding author of the study.Mechanical Pressure in Organizing CellsThe research study, released in Nature Cell Biology, shows that as cells grow in the embryonic incisor tooth, they feel the growing pressure and use this info to arrange themselves. The researchers found that the cells feeling the more powerful pressure stop growing and begin sending signals to organize the other surrounding cells in the tooth.

The researchers discovered that the cells feeling the stronger pressure stop growing and start sending out signals to arrange the other surrounding cells in the tooth.
