(n.) The sphere or globular mass of cells (blastomeres), formed by the clevage of the ovum or egg in the first stages of its development; -- called also mulberry mass, segmentation sphere, and blastosphere. See Segmentation.
Example Sentences:
(1) Laminin was already present on the cell surface at the 2-cell stage, while nidogen was first detectable on compacted 8- to 16-cell stage morulae.
(2) Embryos bisected at blastocyst stages had a higher survival rate in vitro than those bisected at the morula stage.
(3) Rabbit morulae and blastocysts were cultured in conventional culture media [Ham's F10 or BSM II supplemented with bovine serum albumin (BSA) or serum] or in Ham's medium supplemented with synchronous or asynchronous uterine flushings, mostly for 2 days, and afterwards investigated by light and electron microscopy and by autoradiography.
(4) Compaction of the morula is a prerequisite for subsequent differentiation of the mouse embryo.
(5) The development stage of the embryo was determined after examination in toto at 24 h or by counting the morula nuclei at 60 h on histological sections.
(6) Day 6 sheep morulae were cultured in vitro for 48 hours in a bicarbonate-buffered salt solution supplemented with various concentrations of ovine serum or of these components or protein fractions of serum.
(7) Neither stain induced spontaneous activation in mouse oocytes, nor did they impair the in vitro development and implantation of mouse zygotes, two-cell embryos, stressed morulae or blastocysts.
(8) Ham's F-10 medium supplemented with hFCS is routinely checked for its ability to support mouse two-cell embryo development to morulae and blastocysts.
(9) After 6 months storage, the embryos (12, all at the compact morula stage), were thawed in a water bath at 39 degrees C for 30 minutes.
(10) All three treatments decompacted mid-morula-stage embryos within one hour.
(11) It has been reported that these tripronuclear oocytes can develop to grossly normal-appearing morulae and that chromosomally, these embryos could be triploid, diploid, or severely depleted.
(12) Late morulae to blastocysts (n = 80) were collected nonsurgically from naturally mated, estrous-synchronized, superovulated crossbred beef cows.
(13) Pronuclear stages were predominant at 42 to 48 hours and 3 to 8-cell stages at 72 to 96 hours; morulae (containing up to 95 cells) entered the uterus at seven days.
(14) The in vitro development of frozen thawed 4- and 8-cell embryos (23% and 21% respectively) was found to be significantly lower than that of frozen thawed morulae (89%).
(15) In morphological studies, insulin increased the number of blastocysts and decreased the number of morulae by 10% after 54 h culture from 2-cell embryos with EC50s of about 0.95 pM.
(16) Preimplantation stage (16-celled and morula) rabbit embryos were successfully frozen to -196 degrees C. The cooling rate (from a room temperature to 0 degrees C), the presence of the mucin layer surrounding embryos, the ice-seeding treatment and the thawing procedure were examined to determine their effects on the survival of the frozen embryos of Japanese white, New Zealand white and Dutch-Belted rabbits.
(17) Passage through this block (pb1-ratio) was determined by the ratio of compacted morula stages on day 4 of incubation.
(18) A culture system using cells from the uterine tube supported the development of one 1-cell embryo to the morula stage.
(19) Recipients receiving morulae and blastocysts that had incorporated an average of 384 d.p.m.
(20) The process whereby the morula becomes a fluid-filled cyst is called 'cavitation', which can be regarded as the first functional expression of the trophectoderm phenotype.
