Examples of mosaicism

mosaicism isn’t in the Cambridge Dictionary yet. You can help!
When a different chromosomal abnormality was present in all sampled blastomeres (aneuploidy), mosaicism was considered to have originated at the first division.
Nevertheless, we also found a high incidence of mosaicism and this is more worrisome.
Mosaicism at the 8-cell stage cannot be fully detected by preimplantation diagnosis when only one or two cells are analysed.
It would be interesting to know if mosaicism in flukes is confined to germ cells.
Prenatal cases with known mosaicism identified by conventional cytogenetics will be extremely useful in testing the accuracy and sensitivity of this emerging array technology.
The incidence of mosaicism was 16/18 (89%).
The hallmark of the phages' genome structure is genetic mosaicism, reflecting non-homologous recombination events in their ancestry.
In addition to mosaicism, 14% (9/63) of the embryos contained at least one cell with two nuclei, and may also be considered mosaics.
Chromosomal mosaicism throughout human preimplantation development in vitro: incidence, type and relevance to embryo outcome.
Furthermore, placental mosaicism may potentially reduce the reliability of information obtained from sorted trophoblasts.
Chaotic mosaicism in human preimplantation embryos is correlated with a low mitochondrial membrane potential.
A significantly higher incidence of mosaicism was found in this group compared with others that had developed from zygotes with normal pronuclear morphology.
So far there are few studies evaluating the ability of microarray platforms in the detection of chromosome mosaicism in prenatal samples.
In many tissues we observe mosaicism of staining consistent with a cell cycle regulation of expression.
Recurrence risks are very low (<1%) incorporating a small germline mosaicism risk.
The type of mosaicism in most cases was diploid/aneuploid mosaics.
The obtained results show that the extent of genome mosaicism is different for different classes of bacteria.
Mosaicism could arise through several mechanisms including abnormal cell divisions (mitotic non-disjunction or anaphase lag), failure of cytokinesis or endoreduplication.
