Stem cells in small intestinal crypts

Issue Image

Fluorescently stained wholemount of mouse small intestine. A single confocal optical section at the base of the crypts is stained to show nuclei (blue), F-actin (red), and intestinal stem cells (green). Actin-rich smooth muscle fibres forming the muscular mucosae appear as a meshwork around the crypt bases. Lgr5 positive stem cells labelled with green fluorescent protein are found only in the crypt bases. See Dunn, et al. (10.1371/journal.pcbi.1002515).
