Area of Science:
- Developmental Biology
- Evolutionary Biology
- Genomics
Background:
- Vertebrate limb bud development involves complex gene regulatory networks controlling cell patterning, proliferation, and differentiation.
- Understanding limb organogenesis is crucial for developmental biology and evolutionary studies.
Purpose of the Study:
- To review insights into gene regulatory networks governing limb development.
- To examine the evolutionary fin-to-limb transition and digit reductions in tetrapods.
Main Methods:
- Systems biology approaches integrating next-generation 'omics' data.
- Analysis of chromatin architecture and enhancer-promoter interactions.
- Gene network simulations using quantitative datasets.
Main Results:
- Advanced 'omics' and systems biology have deepened understanding of limb development control.
- Insights into the genetic basis of the fin-to-limb transition and digit loss.
Conclusions:
- Gene regulatory networks are central to limb development and evolution.
- Systems biology approaches provide powerful tools for dissecting complex developmental processes.

Development of the Limb Synovial Joints
2.7K
Joints form during embryonic development in conjunction with the formation and growth of the associated bones. The embryonic tissue that gives rise to all bones, cartilage, and connective tissues of the body is called mesenchyme.
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.

Changes in the Appendicular Skeleton with Age
4.0K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

The Evidence for Evolution
50.0K
Genetic variations accumulating within populations over generations give rise to biological evolution. Evolutionary changes can result in the formation of novel varieties and entire new species. These changes are responsible for the diverse forms of life inhabiting the planet. The evidence for evolution suggests that all living organisms descended from common ancestors.

Development of the Lymphatic System
2.6K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...

Bones of the Lower Limb: Tibia and Fibula
14.8K
The tibia is the main weight-bearing bone of the lower leg. It is larger than the fibula with which it is paired. The tibia is also the second longest bone in the body and is located right below the skin. The proximal end of the tibia forms the medial and the lateral condyle, which articulates with the condyles of the femur to form the knee joint. Between the articulating surfaces is the irregular elevated area known as the intercondylar eminence that serves as the inferior attachment point for...

Limits to Natural Selection

Organisms that are well-adapted to their environment are more likely to survive and reproduce. However, natural selection does not lead to perfectly adapted organisms. Several factors constrain natural selection.
