Heart and vessels from stem cells: A short history of serendipity and good luck.

Stem cell research is the product of cumulative, integrated effort between and within laboratories and disciplines. The many collaborative steps that lead to that special "Eureka moment", when something that has been a puzzle perhaps for years suddenly become clear, is among the greatest pleasures of a scientific career. In this essay, the serendipitous pathway from first acquaintance with pluripotent stem cells to advanced cardiovascular models that emerged from studying development and disease will be described. Perhaps inspiration for later generations of stem cell researchers simply to follow whatever they find interesting.
