Development Overview
System Development
The marsupial neonate at birth has a variation between the degree of development of different systems.[3]
- well-developed - digestive, respiratory and circulatory system.
- not well-developed - retains fetal excretory system with a fully functional mesonephric kidney and undifferentiated gonads and genitalia.
Oocyte
Ovarian Follicle Development
Marsupial eggs are enclosed by a series of layers:[4]
- zona pellucida, three zona proteins (ZPA, ZPB, ZPC)
- an additional extracellular matrix coat that lines the zona pellucida also occurs in some species.
- mucoid coat
- outer shell coat.
