Abstract
Peri-gastrulation stage tammar wallaby embryos were cultured for up to 78 h in either Dulbecco's Modified Eagle's Medium or Medium 199, in air/6% CO(2) or 95% O(2)/5% CO(2), and with added fetal calf or wallaby serum. There was little difference between the two media or sera sources, but development was markedly superior for embryos cultured in 95% O(2)/5% CO(2). Many embryos survived even prolonged culture periods up to and over 70 h, and although development continued throughout the culture period, the embryos as a whole became increasingly abnormal. Embryos explanted at the primitive streak/ regressing node stages performed better in vitro than embryos explanted at earlier or later stages..
