Introduction

Sheep with lamb with second (twin) lamb being born.

Domestic sheep (Ovis aries)

  • term gestational days = 145 days

Some Recent Findings

  • Development of morulae from the oocytes of cultured sheep preantral follicles[1] "Sheep preantral follicles (PFs) measuring 250-400 microm in diameter were cultured for six days in serum-free media supplemented differently with growth factors and hormones. ...In combination with T4 and FSH, IGF-I+GH supported the best development of the PFs. Culture of PFs in micro drops or agar gel supported similarly high development. In vitro fertilization of the oocytes from the cultured sheep PFs resulted in the embryos developing to the morula stage for the first time."
  • Viral particles of endogenous betaretroviruses are released in the sheep uterus and infect the conceptus trophectoderm in a transspecies embryo transfer model[2]
