This is composed of structural proteins, like collagen, secreted by specialized fibroblast cells.

ECM由结构蛋白所组成，像是胶原蛋白，由成纤维细胞分泌。

Serum proteins promote cell regeneration, promote dermal layer of fibroblast cells to produce elastin.

血清蛋白促进细胞再生，促使真皮层中纤维母细胞制造弹力蛋白。

For instance, do fibroblast cells arrive from the blood vessels or from skin tissue adjacent to the wound?

比如，成纤维细胞到底来自血管，还是来自伤口周围的皮肤组织？

About two to three days after the wound, the proliferative stage occurs, when fibroblast cells begin to enter the wound.

大约在受伤后的两到三天，成纤维细胞开始进入伤口，意味着第三阶段--增殖阶段的到来。

Lee's team used a retrovirus to transfer the fluorescent gene to dog fibroblast cells, but they could not control where the virus inserted the gene.

Lee的小组使用一种反转录病毒将荧光基因植入狗胚胎成纤维细胞中，但是他们并不能控制这种反转录病毒植入基因的位置。

A team led by Byeong-Chun Lee of Seoul National University in South Korea created the dogs by cloning fibroblast cells that express a red fluorescent gene produced by sea anemones.

韩国首尔大学的BYeong-ChunLee领导的小组通过克隆狗胚胎成纤维细胞创造了这些小狗，而这些成纤维细胞可以表现海葵产生的红色荧光基因。
