The pond snail Lymnaea stagnalis.

Area of Science:

• Developmental Biology
• Translational Medicine
• Neuroscience

Background:

• Lymnaea stagnalis, a freshwater snail, is a long-established research organism.
• It is increasingly used to study molecular mechanisms in developmental biology, learning/memory, and neurodegenerative diseases.
• Its hermaphroditic nature and mating capabilities facilitate genetic studies.

Purpose of the Study:

• To review the use of Lymnaea stagnalis as a model organism.
• To highlight research on chiromorphogenesis (body-handedness) and shell coiling.
• To discuss the identification of the handedness determinant gene.

Main Methods:

• Review of existing literature on Lymnaea stagnalis.
• Focus on gene-editing approaches.
• Analysis of maternal inheritance patterns.

Main Results:

• Lymnaea stagnalis is a valuable model for complex biological processes.
• Chirality in shell coiling (chiromorphogenesis) is a key research area.
• The actin-related gene Lsdia1 was identified as the primary determinant of handedness.

Conclusions:

• Lymnaea stagnalis offers unique advantages for genetic and developmental research.
• Understanding chiromorphogenesis in this model provides insights into fundamental biological mechanisms.
• The identification of Lsdia1 advances molecular studies in developmental biology and related fields.
