概括
胚胎细胞衍生的细胞外囊泡 (AMC-EVs) 帮助患有慢性退行性子宫内膜炎 (CDE) 的母马实现怀孕. 虽然AMC-EVs不会再生子宫组织,但似乎可以恢复至关重要的胎儿与母亲的沟通.
科学领域:
- 生殖医学是一种生殖医学.
- 兽医科学是一门兽医科学.
- 细胞生物学 细胞生物学
背景情况:
- 马类慢性退行性子宫内膜炎 (CDE) 是一种进展性疾病,导致子宫内膜纤维化.
- 这种纤维化会破坏子宫环境,并损害胎儿与母亲的沟通.
- 了解和恢复这种沟通对于马匹的繁殖成功至关重要.
研究的目的:
- 调查胚胎细胞衍生的细胞外囊泡 (AMC-EVs) 的子宫内给药的潜力,以恢复 CDE. 的马匹的胎儿-母体通信.
- 评估AMC-EVs在改善受影响母马的妊娠结果方面的疗效.
主要方法:
- 选择了12只有早期胚胎损失或堕胎史的母马,并诊断出CDE.
- 马匹接受了AMC-EVs的子宫内注射,两组接受了一次或两次治疗周期.
- 进行生殖和组织病理学检查以评估治疗效果.
主要成果:
- 在12只母马中,有11只在AMC-EV治疗后怀孕.
- 在接受一次或两次治疗周期的马匹之间,怀孕结果是相似的,这表明一个周期可能足够.
- 组织病理学检查显示子宫内膜纤维化没有改善,表明AMC-EV可能增强了沟通而不是再生.
结论:

Mesenchymal Stem Cells

Mesenchymal stem cells (MSCs) are adult stem cells that can differentiate into most connective tissue cell types, except for hematopoietic cells, depending upon the source of MSCs. For example, bone-marrow-derived MSCs (BM-MSCs) can differentiate into osteocytes, hepatocytes, and pancreatic and neuronal cells. MSCs can be isolated from various sources such as bone marrow, placenta, adipose tissue, teeth, and Wharton’s jelly, a gelatinous substance in the umbilical cord. The ease of their...

Adult Stem Cells

Stem cells are undifferentiated cells that divide and produce more stem cells or progenitor cells that differentiate into mature, specialized cell types. All the cells in the body are generated from stem cells in the early embryo, but small populations of stem cells are also present in many adult tissues including the bone marrow, brain, skin, and gut. These adult stem cells typically produce the various cell types found in that tissue—to replace cells that are damaged or to continuously...

Embryonic Stem Cells
32.5K
Embryonic stem (ES) cells are undifferentiated pluripotent cells, meaning they can produce any cell type in the body. This gives them tremendous potential in science and medicine since they can generate specific cell types for use in research or to replace body cells lost due to damage or disease.

Embryonic Stem Cells

Embryonic stem (ES) cells were first discovered in mice in 1981 by Martin Evans. In 1998, James Thomson identified a method to isolate embryonic stem cells from humans. Human embryonic stem cells (hESCs) are obtained from 3-5 day old embryos that remain unused after an in vitro fertilization procedure.
ES cells are grown in a culture medium where they can divide indefinitely, creating ES cell lines. Under certain conditions, ES cells can differentiate, either spontaneously into a variety of...

Induced Pluripotent Stem Cells
28.1K
Stem cells are undifferentiated cells that divide and produce different types of cells. Ordinarily, cells that have differentiated into a specific cell type are post-mitotic—that is, they no longer divide. However, scientists have found a way to reprogram these mature cells so that they “de-differentiate” and return to an unspecialized, proliferative state. These cells are also pluripotent like embryonic stem cells—able to produce all cell types—and are therefore...
