Histology Atlas of the Developing Mouse Placenta

Area of Science:

• Developmental Biology
• Reproductive Biology
• Comparative Medicine

Background:

• The mouse is a key model organism in translational research due to similarities with humans.
• Placental development is critical for embryonic survival, involving complex interactions between maternal and embryonic cells.
• Abnormal placentation can lead to embryonic mortality, underscoring the need for detailed developmental atlases.

Purpose of the Study:

• To provide a comprehensive macroscopic and microscopic atlas of normal and abnormal mouse placental development.
• To serve as a reference for researchers studying placental changes in disease models.
• To detail key features from embryonic day 4.5 to 18.5.

Main Methods:

• Macroscopic and microscopic analysis of mouse placentas.
• Documentation of developmental stages from implantation through to term.
• Comparison of normal development with changes observed in disease models.

Main Results:

• Detailed timeline and morphological descriptions of mouse placental development from E4.5 to E18.5.
• Identification of key features of normal placentation, including yolk sac and chorioallantoic placenta formation.
• Illustration of abnormal placental development and its potential impact on embryonic survival.

Conclusions:

• This atlas provides a valuable resource for understanding mouse placental development.
• It will assist researchers in diagnosing and characterizing placental defects in various experimental models.
• Accurate identification of placental changes is essential for advancing translational research.
