Collagen accompanies the extracellular matrix in providing the structure and tensile strength of connective tissues like our ligaments and tendons.

胶原伴随细胞外基质，为韧带和肌腱等结缔组织提供结构和抗拉强度。

As a result, there are fewer functioning microfibrils in the extracellular matrix, and that means there's less tissue integrity and elasticity.

这会导致细胞外基质中正常的微纤丝减少，造成组织完整性和弹性下降。

And although it may not look like it in this particular edible model, the extracellular matrix is mostly made of two components.

They all spring from the same embryonic cells, and their structures are dominated, not by cells, but by an extracellular matrix full of fibers.

它们都来自相同的胚胎细胞，它们的结构并不是由细胞主导，而是由充满纤维的细胞外基质主导。

These growth factors cause the mesangial cells to regress back to their more immature stem cell state known as mesangioblasts and secrete extracellular structural matrix.

这些生长因子使得系膜细胞退化成为未成熟的干细胞状态（成系膜细胞），并分泌细胞外基质框架。

When we look at healthy skin tissue under a microscope, we see the cells that perform various functions connected by an extracellular matrix, or ECM.

当我们在显微镜下观察健康的肌肤组织时，我们可以看见被ECM(细胞外基质)所连接的各种细胞起到了不同的作用。

In the case of your connective tissue, Marfan Syndrome affects those fibers we talked about, that lend structure and support to the extracellular matrix.

就结缔组织而言，马凡综合征会影响我们谈到的那些纤维，这些纤维为细胞外基质提供结构和支持。

This excessive extracellular matrix leads to glomerulosclerosis, hardening and scarr, and diminishes the nephron's ability to filter the blood - over time leading to chronic kidney disease.

这些多余的细胞外基质造成肾小球硬化症，即肾小球硬化、瘢痕化，并减弱肾单位对血液的滤过能力，逐渐发展成慢性肾病。

Neutrophils make an enzyme called neutrophil elastase, a protease capable of breaking down elastin, which is an extracellular matrix protein that gives elasticity and strength to lung tissues.

中性粒细胞产生中性粒细胞弹性蛋白酶，该酶能够水解弹性蛋白；弹性蛋白是一种细胞外基质蛋白，赋予肺组织弹性和韧性。

This extracellular matrix is composed of organic matter, and is primarily a matrix of the protein COLLAGEN and minerals, chiefly CALCIUM, which accounts for 50 to 70% of the bone.

这种细胞外基质由有机物组成，主要是胶原蛋白和矿物质（主要是钙）的基质，钙占骨骼的50 - 70%。

Connective tissue is made up of a mix of cells hanging out in an extracellular matrix, which contains some specific molecules that give your skin some structure and help with things like healing wounds.

When activated, the stellate cells lose vitamin A, proliferate, and start secreting secreting transforming growth factor beta1, or TGF-beta, which then causes them to produce collagen, which is the main ingredient in extracellular matrix, fibrosis, and scar tissue.

激活后的星形细胞失去维生素A，并且开始大量增生，分泌转化生长因子ß，即TGF-ß，随之导致其生成胶原；胶原是细胞外基质、纤维化和疤痕组织的重要成分。
