Spectral karyotyping (SKY) is a novel cytogenetic technique, has been developed to unambiguously display and identify all 24 humans chromosomes at one time without a priori knowledge of any abnormalities involved. SKY can discern the aberrations that can't be detected very well by conventional banding technique and Fluorescent in situ hybridization (FISH). So SKY is hyper accurate, hypersensitive, and hyper intuitionist. We will review the elements and application of SKY in leukemia.

Abnormalities in genes on the X chromosome or large defects in the X chromosome itself cause X-linked intellectual disability. The proband was a 27-year-old man. His medical history included strabismus, cryptorchidism, and severe intellectual disabilities.

The study of chromosomal shape, characteristics, and behavior in somatic cell division (mitosis) during growth and development and in germ cell division (meiosis) during reproduction is known as cytogenetics. Many techniques can be used for cytogenetics, including fluorescent hybridization (FISH), spectral karyotyping (SKY), multicolor FISH (M-FISH), microarray, and optical genome mapping (OGM). OGM is a novel genome-wide method that can identify structural variants (SVs) and copy number variants (CNVs) with only one test.

Endothelial cells (ECs) maintain vessel tone and barrier integrity, regulate blood homeostasis, and prevent the extravasation of leukocytes under normal physiological conditions. Because of the limited lifespans and batch-to-batch differences with respect to the genetic make-up of primary ECs, established immortal EC lines are extensively used for studying endothelial biology. To address this issue, the immortal endothelial cell line EA.

Karyotype coding, which encompasses the complete chromosome sets and their topological genomic relationships within a given species, encodes system-level information that organizes and preserves genes' function, and determines the macroevolution of cancer. This new recognition emphasizes the crucial role of karyotype characterization in cancer research. To advance this cancer cytogenetic/cytogenomic concept and its platforms, this study outlines protocols for monitoring the karyotype landscape during treatment-induced rapid drug resistance in cancer.

The study of chromosomes without or with molecular DNA probes provides crucial insight for understanding research findings, as well as refining diagnosis, prognosis, and therapeutics in clinical settings. Here, we present a protocol for chromosome preparation, conventional G-banding, locus-specific fluorescent in situ hybridization, and spectral karyotyping for both mouse and human samples. This protocol optimizes the preparation of chromosomes from mouse and human cells for subsequent conventional and molecular cytogenetic analysis.
