I explore the fundamental regulation of satellite cells (SC) in muscle; I aim to improve animal-meat production by understanding muscle growth. The known biology of SC, stem cells in muscle, and 2-way SC interactions with muscle fibers and tissues is mostly based on mouse muscle. SC activation to cycle is the first step in growth and regeneration; my explicit focus on that step is nearly unique. Since 2009, I initiated a comparative approach to study SC regulation and activation: we focused on the regulation of zebrafish muscle SC and differences from that of mouse SC, since new findings could be potent if applied to boost aquaculture fish-meat production. The proposed work aims to understand the interplay of SC activity with muscle development, function and regeneration and will advance Canadian innovation capacity in promoting high-quality meat growth in animals.

我探索肌肉中卫星细胞（SC）的基本调节；我的目标是通过了解肌肉生长来提高动物肉类产量。已知的 SC 生物学、肌肉中的干细胞以及 SC 与肌肉纤维和组织的双向相互作用主要基于小鼠肌肉。 SC激活进入循环是生长和再生的第一步；我对这一步的明确关注几乎是独一无二的。自 2009 年以来，我开始采用比较方法来研究 SC 调节和激活：我们重点关注斑马鱼肌肉 SC 的调节以及与小鼠 SC 的差异，因为如果将新发现应用于提高水产养殖鱼肉产量，可能会很有效。拟议的工作旨在了解 SC 活动与肌肉发育、功能和再生的相互作用，并将提高加拿大在促进动物高质量肉类生长方面的创新能力。
