Gastrulation01:56

Gastrulation

53.1K
Gastrulation establishes the three primary tissues of an embryo: the ectoderm, mesoderm, and endoderm. This developmental process relies on a series of intricate cellular movements, which in humans transforms a flat, “bilaminar disc” composed of two cell sheets into a three-tiered structure. In the resulting embryo, the endoderm serves as the bottom layer, and stacked directly above it is the intermediate mesoderm, and then the uppermost ectoderm. Respectively, these tissue strata...

Neurulation

40.4K
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...

Zygotic Development And Stem Cell Formation

6.4K
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...

Area of Science:

  • Developmental Biology
  • Neuroscience
  • Stem Cell Biology

Background:

  • Mammalian development requires precise signaling for pattern formation and morphogenesis.
  • Studying complex developmental processes in vivo is challenging due to confounding factors.
  • Three-dimensional (3D) organoids offer a promising in vitro model for developmental studies.

Purpose of the Study:

  • To address the heterogeneity and variability in current organoid models.
  • To present an optimized protocol for reproducible neural tube organoid (NTO) generation.
  • To facilitate the study of early central nervous system (CNS) development.

Main Methods:

  • Development of stable in vitro culture conditions for NTOs.
  • Incorporation of comprehensive troubleshooting strategies.
  • Utilizing embryonic stem cells (ESCs) or induced pluripotent stem cells (iPSCs) for organoid derivation.

Main Results:

  • Achieved reliable and reproducible generation of NTOs.
  • Established stable culture conditions minimizing variability.
  • Provided a robust model for investigating neural induction and CNS patterning.

Conclusions:

  • The optimized NTO protocol enhances reproducibility and reduces material usage.
  • NTOs serve as an adequate model for studying complex questions in early CNS development.
  • This protocol supports further research into neural induction and patterning mechanisms.
