Morula

Fig. 2. Methods for production of identical catde. (a) Embryo spHtting. A microdissection knife is used to cut an early embryo into two identical halves, (b) Embryo cloning. A cell from a morula stage embryo is removed and then inserted into an oocyte that has had its nucleus removed. EoUowing fusion of the two cells the newly produced one-ceU embryo is identical to the original morula. The procedure can be repeated to give multiple copies of the original...

Human embryonic stem cells (hESCs) were first derived from the inner cell mass (ICM) from the blastocyst stage (-100-200 cells) of embryos generated by in vitro fertilization [35,36]. In humans the blastocyst is an early-stage embryo, approximately 4 to 5 days old. The blastocyst can be formed by means of either in vitro fertilization or somatic cell nuclear transfer, in which the nucleus of a somatic cell is combined with an enucleated oocyte. Methods have been developed to derive hESCs from the late morula stage (30-40 cells) and from arrested embryos (16-24 cells incapable of further development), and more recently from single blastomeres isolated from 8-cell embryos (37). 

Blood cells of C. intestinalis showed low and variable levels of vanadium in morula cells (154). In this species the primary vanadium storage site was determined to be the granular amoebocyte. It was first concluded that significant vanadium is present in the morula cells of the species A. mentula and Ascidiella aspersa, but the various cell types were not distinguishable (155), When the same two species were reexamined with improved fixation methods it was concluded that sig-...
