Plant stem, neural stem cells, or a alveoli in lungs? How did you fare?
Though not the most popular guess, this is actually a micrograph of neural stem cells specializing into mature neurons. Blue staining marks the nuclei of cells, while green and red staining mark growing axons, which can be seen growing on the periphery. This intricate pattern probably arose due to a specialized matrix on which the cells were cultured. Neural stem cells hold tremendous promise in regenerative medicine and drug discovery as they provide an essentially limitless supply of cells that can be turned into desired cell types of the nervous system.
