Mammalian ova have not been studied as thoroughly as the eggs of lower vertebrates. Increasing interest in the physiology and biochemistry of mammalian embryogenesis in recent years has been met with little quantitative information. Up to now there have been no direct chemical analyses of mammalian ova published. Reported here are the dry mass and protein and lipid contents of the single cell fertilized mouse ovum. The mouse was chosen because of its frequent use as an experimental animal for the study of developmental genetics and because large numbers of mouse ova can be obtained with relative ease. Single cell stage ova from mated females were chosen as the starting point from which to follow these parameters through cleavage and blastocyst formation, although it must be realized that a proportion of such ova would not be fertilized.

Following a virtual meeting in 2020, we are delighted to announce that the fifth iteration of our popular Journal Meeting will be held from 11-14 September 2022 at the historic Wotton House, Surrey. Registration is open now.
Special Issue: The Immune System in Development and Regeneration
(update)-ImmuneSI.png?versionId=3737)
Our latest special issue is now complete. It showcases articles that add to the repertoire of immune cell functions during development, repair and regeneration, and provide insights into the developmental pathways leading to the generation and dispersal of these cells.
Propose a new Workshop

Our Workshops bring together leading experts and early-career researchers from a range of scientific backgrounds. Applications are now open to propose Workshops for 2024, one of which will be held in a Global South country.
Preprints in Development
(update)-InPreprints.png?versionId=3737)
As part of our efforts to support the use of preprints and help curate the preprint literature, we are delighted to launch a new article type: ‘In preprints’. These pieces will discuss one or more recent preprints and place them in a broader context. You can read the first article here.
FocalPlane Network launched
