Cytogenetic analysis of human blastocysts

Prenatal Diagnosis, 2002
AbstractThe human blastocyst is key to understanding the aetiology of constitutional chromosome abnormalities in our species.ObjectivesTo investigate the range and incidence of chromosome abnormalities in a large series of human blastocysts, using classic cytogenetic techniques.MethodsUsing thymidine, cell division is synchronized in spare five‐to ...

Classical and Molecular Cytogenetic Analysis

2012
Cytogenetic analysis is performed on cell cultures for several reasons, notably, to perform identity checks by verifying species of origin or the retention of key chromosome rearrangements in cell lines described previously. De novo chromosome analysis is usually performed when characterizing cancer cell lines for the presence of neoplastic ...

Cytogenetic analysis of dedifferentiated chondrosarcoma

Cancer Genetics and Cytogenetics, 1996
Cytogenetic analysis of a dedifferentiated chondrosarcoma with a fibrosarcomatous component revealed the following chromosomal complement: 47,XX,i(1)(q10), add(6)(q13),+7,+8,t(10;12) (p11.2;q11.2),+14,-15,-17, add(19)(q13,4). Chromosome studies of dedifferentiated chondrosarcoma are sparse.

Interphase cytogenetic analysis of gliomas

Clinical Neurology and Neurosurgery, 1992
Interphase cytogenetics is the application of nonradioactive in situ hybridization with chromosome-specific DNA probes to interphase nuclei. The possibilities and limitations of this new technique for the study of chromosomal aberrations in gliomas are discussed.

Cytogenetic analysis of dermatofibrosarcoma protuberans

Cancer Genetics and Cytogenetics, 1990
A case of dermatofibrosarcoma protuberans that occurred in an old burn scar over the anterior chest wall of a 46-year-old man is reported. Cytogenetic analysis of the tumor cells showed the presence of two abnormal clones: 47,XY, +8 and 48,XY, +8, +r.

Cytogenetic Analysis of Tumor Clonality

2011
All or almost all neoplasias subjected to systematic cytogenetic scrutiny have been found to harbor acquired chromosomal aberrations. The paradigm stemming from the study of hematopoietic malignancies and sarcomas is that cancers are of monoclonal origin (i.e., they have developed from a single transformed somatic progenitor) because all the neoplastic

Cytogenetic analysis of renal angiomyolipoma

Genes, Chromosomes and Cancer, 1992
AbstractChromosome analysis of a benign, unilateral, renal angiomyolipoma revealed the karyotype 44,XX, –8, –12, –14, –21, + der (8q14q), + der(12)(12pter → 12q14‐15:: 12q24 → 12q14–15::21q21 → 21 qter). This indicates that structural changes of 12q13‐15, which are so frequently observed in the common malignant and benign lipogenic tumors, may also ...

Cytogenetic Analysis and Reporting

2011
Use of appropriate methods to produce analysable metaphase spreads and high-quality fluorescence in situ hybridization (FISH) and array results is critical to successful cytogenetic analysis of haematological malignancies, but the analysis and reporting of the findings of these tests are equally important as it is the final report that clinicians rely ...

Cytogenetic Analysis of a Parachordoma

Cancer Genetics and Cytogenetics, 1998
We report the cytogenetic and histopathological findings in a 7-year-old female child with an intranasal tumor that is most consistent with a parachordoma. Karyotypic analysis of the tumor revealed clonal numerical and structural chromosome abnormalities. Seven cells displayed recurrent changes: der(2)t(2;4), del(3q), and the loss of chromosomes 9, 10,
