morula

 [mor´u-lah]
a solid mass of cells (blastomeres) resembling a mulberry, formed by cleavage of a zygote (fertilized ovum).

mor·u·la

(mōr'ū-lă),
The solid mass of blastomeres resulting from the early cleavage divisions of the zygote. In oocytes with little yolk, the morula is a spheroid mass of cells; in forms with considerable yolk, the configuration of the morula stage is greatly modified.
[Mod. L. dim. of L. morus, mulberry]

morula

(môr′yə-lə, môr′ə-)
n. pl. moru·lae (-lē′)
The spherical embryonic mass of blastomeres formed before the blastula and resulting from cleavage of the fertilized ovum.

mor′u·lar adj.
mor′u·la′tion n.

morula

An early stage of embryonic development characterised by a solid ball of about 32 primitive cells.

mor·u·la

(mōr'yū-lă)
The solid mass of blastomeres resulting from the early cleavage divisions of the zygote.

morula

An early stage in the development of the embryo at which it consists of a solid spherical ball of apparently identical cells.

morula

a solid ball of cells resulting from cleavage of a fertilized ovum. It is formed of a mass of BLASTOMERES which subsequently form a BLASTULA.

Zhang, the lead investigator of that study, strongly suspects that the women in the day 5 group with low [beta]-hCG levels probably were receiving embryos at the morula stage.
Effects of temperature during IVM and antioxidants in embryo culture on developmental competence of embryos and cell numbers of blastocyst were analyzed by the general linear model of the SPSS 17.0 package program (SPSS, Chicago, IL, USA) after than arcsine-transformation and logl0 transformation (cleaved embryos, morula and blastocyst yields were done arcsine-transformation; cell numbers of blastocyst were logl0 transformation).
Our results indicated that immunocytes (both phagocytes and cytotoxic morula cells) are active in the transcription of genes involved in ROS detoxification, and their activity is modulated during the blastogenetic cycle and by the presence of Cd.
Las observaciones se efectuaron cada una hora desde el termino del desove hasta el estado de morula y luego diariamente hasta la eclosion.
To evaluate the effects of Ang II on [Na.sup.+][K.sup.+]/ATPase subunits expression, the morula and blastocysts on day 8 were immunostained with specific primary and a common fluorescein isothiocyanate (FITC)-conjugated secondary antibody.
The final numbers of embryos at various stages (2-, 4-, 8-, 16-, morula, and blastocyst) were recorded at day 9.
El mayor porcentaje de embriones se encontraba en estadio de blastocisto eclosionado, tanto al dia 6 como al dia 7 post copula, y solo se encontro un embrion en estadio de morula al dia 5; resultado que difiere al estudio de Bravo et al.
Los resultados muestran que los estadios de desarrollo embrionario predominantes fueron los estadios de morula, blastocisto temprano y blastocisto con 32.6, 38 y 18.5% respectivamente.
(2010), em camundongos, podemos dividir o padrao de expressao genica inicial em tres etapas distintas: primeira etapa (zigoto); segunda etapa (embriao com duas e quatro celulas); e, por fim, a terceira etapa, que corresponde aos estagios embrionarios de 8 celulas, morula e blastocisto.
La transferencia de una morula temprana resulta en menores tasas de prenez que cuando se transfieren embriones en estadio mas avanzado (9).
However, there seems to be no data available on the survival of in vitro produced bovine embryos that are biopsied at different times of pre-compacted morula stage, considering embryonic cellularity.
