Zebrafish Heart

Caption

Pictured is the heart of a living, 2-day-old zebrafish with the membranes of heart muscle cells shown in blue and their nuclei in red, provided by CZI Imaging Scientist Michael Weber of the Morgridge Institute for Research. The heart is about 200 micrometers (akin to a thick human hair). Scientists study animals like zebrafish -- a tropical fish sporting horizontal blue stripes -- to learn about human diseases.
