Introduction

The opossums () are a family of nocturnal semi-arboreal marsupials including the cuscuses, brushtail possums, and their close relatives.


Some Recent Findings

  • Developmental origins of precocial forelimbs in marsupial neonates[1] "Marsupial mammals are born in an embryonic state, as compared with their eutherian counterparts, yet certain features are accelerated. The most conspicuous of these features are the precocial forelimbs, which the newborns use to climb unaided from the opening of the birth canal to the teat. The developmental mechanisms that produce this acceleration are unknown. Here we show that heterochronic and heterotopic changes early in limb development contribute to forelimb acceleration. Using Tbx5 and Tbx4 as fore- and hindlimb field markers, respectively, we have found that, compared with mouse, both limb fields arise notably early during opossum development."
  • Expression of mRNAs encoding oestrogen receptor (ER) alpha and ERbeta, androgen receptor and progesterone receptor during gonadal and follicular development in the marsupial brushtail possum[2] "Expression of ERalpha and/or ERbeta mRNA was observed from birth, initially in cells of the blastema, then in the medullary cords from Day 20. ERalpha was expressed in the oocytes and granulosa cells of secondary and antral follicles. Preovulatory follicles did not express ERalpha mRNA, although their oocytes were not examined for any gene. ERbeta mRNA was observed in oocytes at all follicular stages examined, but was not consistently observed in granulosa or theca cells. Expression of AR mRNA before Day 40 was very faint; thereafter, expression was observed in the medullary cords, peaking between Days 60 and 120. Oocytes, granulosa cells and theca of secondary and antral, but not preovulatory, follicles expressed AR mRNA. PR mRNA was expressed throughout the gonad by Day 20. Granulosa cells of some secondary and antral follicles and theca of antral follicles expressed PR mRNA."

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.
