Cancer, 1976 One of the most exciting and useful developments in modern oncology has been the recognition that certain biochemical tags can be used as cell markers in diagnosis, in monitoring the effects of anti-tumor therapy, and in follow-up to detect tumor recurrence. The measurement of chorionic gonadotropin (CG) in women with choriocarcinoma and/or gestational

Responsiveness of bovine cumulus-oocyte-complexes (COC) to porcine and recombinant human FSH, and the effect of COC quality on gonadotropin receptor and Cx43 marker gene mRNAs during maturation in vitro [PDF]
, 2003 Substantially less development to the blastocyst stage occurs in vitro than in vivo and this may be due to deficiencies in oocyte competence. Although a large proportion of bovine oocytes undergo spontaneous nuclear maturation, less is known about ...

Hormone Receptor Site Maturation in the Secondary Sex Organs of Immature Male and Female Rats [PDF]
, 1976 The effect of a combined dose of pregnant mares\u27 serum (PAAS) and human chor ionic gonadotropin (HCG) on male and female rats 2-25 days old was studied. Groups of animals were given injections for three days, then sacrificed on the fourth day.

, 2013 The size of mature oocytes is similar across mammalian species, yet the size of ovarian follicles increases with species size, with some ovarian follicles reaching diameters more than 1000-fold the size of the enclosed oocyte.

Advanced Science, EarlyView.Mammalian cloning via SCNT is limited by several epigenetic barriers. Kdm4d/Kdm5b overexpression plus TSA treatment overcomes epigenetic barriers during pre‐implantation development, while tetraploid complementation replaces defective extraembryonic lineages to bypass H3K27me3 imprinting loss to overcome epigenetic barriers in post‐implantation ...
