Muscle growth and regeneration is regulated by obligate tissue resident muscle stem cells. Here, we review the current understanding of the role of muscle stem cells in muscle growth, specifically discussing the distinct processes used by amniotes and teleosts, and in muscle regeneration, addressing the importance of muscle stem cell heterogeneity, and the niche.

The fetal‐placental connection in the mouse gastrula. Recent discoveries at the posterior embryonic‐extraembryonic interface of the mouse gastrula expand upon the traditional view of the allantois and associated tissues, and reveal new elements that, in the current view, together create and pattern the fetal‐placental arterial connection, whose mechanism of establishment and alignment along the anterior–posterior body axis are the focus of this review article. ACD, allantoic core domain, or extraembryonic component of the primitive streak; al, allantois; am, amnion; AX, allantois‐associated extraembryonic visceral endoderm; bi, blood island; CASP3, activated CASPASE‐3 protein; ch, chorion; dAX, distal [to] allantois‐associated extraembryonic visceral endoderm; ips, intra‐embryonic component of the primitive streak; rod, visceral‐endoderm derived bifurcation into the allantois and associated with the ACD; xve, extraembryonic visceral endoderm; vys, visceral yolk sac. The white asterisk within the red circle is the vessel of confluence.

Reconstructing the earliest events in animal evolution, including the origin of novel cell types and developmental signaling pathways, depends upon comparative research between traditional research models with four understudied lineages: sponges, ctenophores, placozoans, and cnidarians.
