But sometimes biologists have a hard time seeing. One particularly vexing challenge is seeing all the molecules in an intact tissue sample, down to the level of single cells, simultaneously. Detecting the location of hundreds or thousands of biomolecules—from lipids to metabolites to proteins—in their native environment allows researchers to better understand their functions and interactions. Unfortunately, scientists don't have great tools to accomplish this task. /news/2025-04-technique-tissues-hundreds-biomolecules-cells.html Biotechnology Molecular & Computational biology Tue, 22 Apr 2025 14:37:04 EDT news664551422 During morphogenesis—the process by which living organisms take shape—cells collectively position themselves in specific ways, leading to the development of tissues and organs.
