Resumen
Las vías de desarrollo cruciales para el patrón corporal se conservan en todas las especies. Las interrupciones en estos mecanismos conservados causan malformaciones congénitas, como se ve en el síndrome de DiGeorge, la holoprosencefalia y los trastornos del gen HOX.
Área de la Ciencia:
- Biología del desarrollo Biología del desarrollo.
- Genética Humana Genética Humana.
- Biología evolutiva Biología evolutiva.
Sus antecedentes:
- Los mecanismos fundamentales de patrones corporales se conservan en todos los vertebrados e incluso de los invertebrados a los vertebrados.
- Los defectos en estos procesos de desarrollo conservados son una causa significativa de los síndromes de malformación congénita.
- Los avances recientes están aclarando rápidamente los fundamentos embriológicos y genéticos de estos trastornos.
Objetivo del estudio:
- Para resaltar los avances recientes en la comprensión de las malformaciones congénitas.
- Para ilustrar aspectos clave de estos trastornos a través de tres ejemplos específicos.
- Explorar la base genética y embriológica de los defectos del desarrollo.
Principales métodos:
- Revisión de la literatura científica reciente sobre biología del desarrollo y genética.
- Centrarse en tres estudios de caso: desarrollo del aparato faríngeo (síndrome de DiGeorge), desarrollo del cerebro anterior (holoprosencefalia) y genes HOX humanos.
- Integración de hallazgos embriológicos y genéticos.
Principales resultados:
- Recientemente se ha avanzado en la comprensión de las bases moleculares y genéticas de las malformaciones congénitas.
- El estudio examina la perturbación del desarrollo del aparato faríngeo en el síndrome de DiGeorge.
- También investiga los defectos de inducción / diferenciación del cerebro anterior en la holoprosencefalia y el papel de los genes HOX humanos.
Conclusiones:
- Comprender las vías de desarrollo conservadas es fundamental para comprender las malformaciones congénitas.
- El síndrome de DiGeorge, la holoprosencefalia y los trastornos relacionados con el gen HOX ejemplifican el impacto de las interrupciones en los procesos fundamentales del desarrollo.
- La investigación continua en embriología y genética ofrece información sobre la prevención y el tratamiento de defectos de nacimiento.

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...
01:10Zygotic Development And Stem Cell Formation
The development of all multicellular organisms starts with the fusion of haploid cells called sperm and egg to form a diploid zygote. A zygote is a totipotent cell that can develop into a complete organism. The zygote undergoes cell division or cleavage to form an 8-cell mass. Until this stage, the cells are spherical, loosely attached, and remain totipotent. Totipotent cells are capable of developing both the embryonic and the extraembryonic tissues. However, as they continue to divide, they...
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...
01:15Development of the Sexual Organs in the Embryo and Fetus
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the male...
