Cardiac-resident stem cells are likely sequestered as reserve cells within myocardial niches during the course of embryonic cardiogenesis, although they may also be recruited from external sources, such as bone … WebHistory. The earliest fate maps were based on direct observation of the embryos of ascidians or other marine invertebrates. Modern fate mapping began in 1929 when Walter Vogt marked the groups of cells using a dyed agar chip and tracked them through gastrulation. In 1978, horseradish peroxidase (HRP) was introduced as a marker. HRP …
