Summary
Tagmosis, the grouping of body segments for specialized functions, is weakly present in echinoderms, unlike in annelids, arthropods, and chordates. This study explores tagmosis patterns across various echinoderm groups, revealing its varied expression.
Area of Science:
- Developmental Biology
- Evolutionary Biology
- Zoology
Background:
- Tagmosis is a fundamental concept in metamerism, observed in annelids, arthropods, and chordates, where body segments fuse for specialized functions.
- Echinoderms, a major group of metameric animals, have been less explored for tagmosis, despite possessing segmented body plans.

01:19Clinical Applications of Epidermal Stem Cells
Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own EpiSCs...
01:19Overview of Regeneration and Repair
Regeneration and repair processes are critical in healing damages caused by injury, disease, and aging. In regeneration, the damaged tissue is entirely replaced with new growth that restores the original architecture and function. In contrast, tissue repair usually results in a fixed tissue architecture involving scar formation. Scars generally do not reestablish tissue function and may also exhibit structural abnormalities at the injury site.

01:33Whole Body Regeneration
Regeneration is the process of restoring injured or lost tissues, organs, or body parts. While simpler organisms generally show greater ability to regenerate their whole body, few complex animals show similarly exceptional regeneration. For example, planarian flatworms have a unique regenerative potential making them a popular study organism among biologists to understand the mechanisms of whole body regeneration. Other organisms, such as hydra, also show extreme regeneration potential; even...
