Random labeling of cardiac precursors in the course of em bryonic improvement also revealed the existence of rare clones that contributed to each FHF and SHF lineages and that could repre sent a widespread cardiovascular progenitor for each heart fields (Meilhac et al., 2004). Recent research showed that, for the duration of mouse embryonic improvement, tripotent MCPs which might be able to differen tiate at the clonal level into CMs, SMCs, and ECs could be marked and isolated according to Brachyury (Bry) and Flk1 (Kattman et al., 2006) or Isl1 and Flk1 expression (Moretti et al., 2006), whereas bipotent MCPs that give rise to CM and SMC lineages could be iso lated determined by Nkx2-5 and cKit expression (Wu et al., 2006). These studies demonstrated that cardiac cells arise from the differ entiation of multipotent progenitors, together with the ability to differenti ate at the clonal level into the distinct cardiovascular lineages (Kattman et al., 2006; Moretti et al., 2006; Wu et al., 2006).2011 Bondue et al.
