Temnopleurus as an emerging echinoderm model

Area of Science:

• Developmental Biology
• Cell Biology
• Marine Biology

Background:

• Sea urchins are established models in cell and developmental biology.
• Developing transgenic sea urchin lines and maintaining genetic stocks is crucial for advancing research.
• Existing models have limitations, necessitating the exploration of new species.

Purpose of the Study:

• To introduce Temnopleurus reevesii as a novel sea urchin model organism.
• To describe methods for culturing T. reevesii from embryo to adult stages.
• To lay the groundwork for establishing inbred strains and future genetic manipulation in this species.

Main Methods:

• Culturing of Temnopleurus reevesii embryos, larvae, juveniles, and adults under laboratory conditions.
• Detailed protocols for maintaining live sea urchin populations.
• Characterization of T. reevesii embryonic developmental parameters, including temperature tolerance and transparency.

Main Results:

• Temnopleurus reevesii exhibits a broad temperature tolerance (15°C–30°C).
• Embryos and larvae of T. reevesii possess high transparency, advantageous for live imaging.
• Successful methods for the continuous culture of T. reevesii were established.

Conclusions:

• Temnopleurus reevesii is a promising new model organism for cell and developmental biology research.
• The described culturing methods facilitate the development of next-generation sea urchin lines.
• This work supports future efforts in creating transgenic T. reevesii and establishing genetic stocks.
