This was based on the observation that, if pregnant mice were ovariectomized a few hours after mating and given progesterone before Day 3, the mitosis which normally occurs in the uterine glands and to a lesser extent in the luminal epithelium on Day 3 (Finn &amp; Martin, 1967) is suppressed.<\/jats:p>\n                  <jats:p>The object of the present work was to see whether exogenous progesterone given to entire pregnant mice before Day 3 would cause a similar change in the pattern of uterine mitosis on Day 3<\/jats:p>","DOI":"10.1530\/jrf.0.0250299","type":"journal-article","created":{"date-parts":[[2007,5,15]],"date-time":"2007-05-15T17:17:08Z","timestamp":1179249428000},"page":"299-300","update-policy":"https:\/\/doi.org\/10.1530\/rep\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["THE ONSET OF PROGESTERONE SECRETION DURING PREGNANCY IN THE MOUSE"],"prefix":"10.1093","volume":"25","author":[{"given":"C.
