Most cell signals are chemical in nature. For example, prokaryotic organisms have sensors that detect nutrients and help them navigate toward food sources. In multicellular organisms, growth ...

Andrew T. Lombardo, PhD, assistant professor of biochemistry, has received a $1.9 million National Institutes of Health grant to study cell polarity signaling.

Biomedical researchers look to these secreted proteins for information on cell-to-cell communication, cell signaling ... "Using a simple fluorescence microscope, we are able to simultaneously ...
