概括
辅助生殖技术 (ART) 改善了结果,但可能会带来风险. 本综述映射了与ART相关的出生缺陷和后代表观遗传变化的证据.
科学领域:
- 生殖医学和发育生物学.
背景情况:
- 辅助生殖技术 (ART) 取得了显著的进步,通过更好的胚胎培养,提高了怀孕率,减少了多胎.
- 实验室胚胎培养条件与活体环境的动态不同,可能会影响发育.
- 卵巢刺激,体外受精和冷保存等ART程序可能会影响早期胚胎发生期间的关键表观遗传重编程.
研究的目的:
- 绘制有关ART潜在风险的现有证据,重点关注后代的出生缺陷和表观遗传结果.
- 识别有关ART程序对健康的长期影响的文献上的差距.
主要方法:
- 根据PRISMA-ScR (系统性审查的首选报告项目和范围审查的元分析扩展) 的指导方针进行了范围审查.
- 该审查系统地搜索和综合了有关ART相关风险的证据,包括表观遗传改变和出生缺陷率.
主要成果:
- 在全球范围内,人工智能技术已经导致超过1000万名婴儿出生,其中大多数婴儿都是健康的.
- 人们仍然担心与ART程序相关的潜在出生缺陷和发育变化,包括伴生体/胚胎处理和体外培养条件.
- 在植入前发育期间,ART对关键表观遗传重编程的影响及其对后代健康的长期影响需要进一步研究.
结论:
- 虽然ART非常成功,但需要进行持续的研究,以充分了解和减轻对后代的潜在风险.
- 需要进一步的研究来澄清ART,表观遗传修饰和出生缺陷的发生率之间的关系.
- 确保通过ART怀孕的儿童的长期健康和安全仍然是生殖医学重点关注的关键领域.

CRISPR
52.9K
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced...

Embryonic Stem Cells
3.7K
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...

In Vitro Fertilization
395
In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...
