|August 5, 1998
Summary
A 14-week spontaneous abortion revealed a 35-day-old embryo with lumbosacral spina bifida. This embryo also exhibited trisomy 9, a chromosomal abnormality.
Area of Science:
- Developmental biology
- Human genetics
- Reproductive medicine
Background:
- Spontaneous abortion is a common complication of pregnancy.
- Early embryonic development is crucial for successful gestation.
- Chromosomal abnormalities are a leading cause of miscarriage.
Observation:
- Examination of products from a 14-week spontaneous abortion.
- Identified an embryo at approximately 35 days of developmental age.
- The embryo presented with a cystic lumbosacral spina bifida.
Findings:
- The embryo was diagnosed with trisomy 9, a specific chromosomal aneuploidy.
- Cystic lumbosacral spina bifida, a severe neural tube defect, was observed.
- The combination of trisomy 9 and spina bifida in this early embryo.
Implications:
- This case highlights the potential link between chromosomal abnormalities and severe congenital malformations.
- Understanding such associations is vital for genetic counseling and prenatal diagnostics.
- Further research into trisomy 9's role in early embryonic development and neural tube defects is warranted.

01:49Meiosis I
Meiosis is a carefully orchestrated set of cell divisions, the goal of which—in humans—is to produce haploid sperm or eggs, each containing half the number of chromosomes present in somatic cells elsewhere in the body. Meiosis I is the first such division, and involves several key steps, among them: condensation of replicated chromosomes in diploid cells; the pairing of homologous chromosomes and their exchange of information; and finally, the separation of homologous chromosomes by a...
01:30Neurulation
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the anterior...
01:29Nondisjunction
During meiosis, chromosomes occasionally separate improperly. This occurs due to failure of homologous chromosome separation during meiosis I or failed sister chromatid separation during meiosis II. In some species, notably plants, nondisjunction can result in an organism with an entire additional set of chromosomes, which is called polyploidy. In humans, nondisjunction can occur during male or female gametogenesis and the resulting gametes possess one too many or one too few chromosomes.
02:57Meiosis vs. Mitosis
Cell division is necessary for growth and reproduction in organisms. Mitosis aids cell growth and development by dividing somatic cells. In contrast, meiosis causes the division of germ cells and plays an essential role in sexual reproduction. Due to their unique functional requirements, mitosis and meiosis differ from each other in multiple aspects.
Before the start of mitosis and meiosis I, the cell synthesizes DNA, resulting in two homologous copies of each chromosome. DNA synthesis is...

01:21Nondisjunction
Nondisjunction is the failure of homologous chromosomes or sister chromatids to separate correctly and move to the opposite poles of the cells. This produces daughter cells with abnormal chromosome numbers. Nondisjunction is common during anaphase I or anaphase II of meiosis. Mutations in synaptonemal complex proteins that attach homologous chromosomes increase the chances of nondisjunction in anaphase I of meiosis I. In contrast, mutations in topoisomerases and condensins that hold sister...
01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
