Different tissues show distinct regenerative capacities with an organism and across the phylogeny. What underlies this diversity in regenerative ability at cellular and molecular level is far from clear. Building on foundational discoveries in zebrafish, this study seeks to determine if this capacity could, in part, be explained through the properties of a component of the innate immune system, the macrophage, which preliminary data shows generates a transient pro-regenerative muscle stem cell niche in zebrafish. This study will determine if macrophage subtypes acts to coordinate regeneration in other tissues and systems and if a programable pro-regenerative cell can be made in vitro that stimulate regeneration in different settings.

不同的组织显示出不同的再生能力与生物体和整个生殖系统。在细胞和分子水平上，是什么导致了这种再生能力的多样性还远未清楚。基于斑马鱼的基础发现，这项研究试图确定这种能力是否可以部分通过先天免疫系统的一个组成部分巨噬细胞的特性来解释，初步数据显示巨噬细胞在斑马鱼中产生了一个短暂的促再生肌肉干细胞生态位。这项研究将确定巨噬细胞亚型是否可以协调其他组织和系统的再生，以及是否可以在体外制造可编程的促再生细胞，以刺激不同环境中的再生。
