A hybrid cell line is a fusion of cells from two different cell types. When the membrane of two cells merge, the nuclei combine to form a polykaryote (poly- multiple; karyon- chromosome). [1] These fusions can happen spontaneously as in the case of tumor hybrid cells, or may be induced by a variety of laboratory techniques.
a Cells of the same lineage fuse to form a cell with multiple nuclei, known as a syncytium. The fused cell can have an altered phenotype and new functions such as barrier formation. b Cells of different lineage fuse to form a cell with multiple nuclei, known as a heterokaryon. The fused cells might have undergone a reversion of phenotype or ...
Fusion of two cells produces a heterokaryon, i.e., a single hybrid cell with two nuclei, one from each of the cells entering fusion. Subsequently, the two nuclei also fuse to yield a hybrid cell with a single nucleus. A generalized scheme for somatic cell hybridization may be described as follows. Appropriate human and mouse cells are selected ...
Karyogamy in the context of cell fusion. 1-haploid cells, 2-cell fusion, 3-single cell with two pronuclei, 4-fusing pronuclei (karyogamy), 5-diploid cell Karyogamy is the final step in the process of fusing together two haploid eukaryotic cells, and refers specifically to the fusion of the two nuclei .
In membrane biology, fusion is the process by which two initially distinct lipid bilayers merge their hydrophobic cores, resulting in one interconnected structure. If this fusion proceeds completely through both leaflets of both bilayers, an aqueous bridge is formed and the internal contents of the two structures can mix.
During the early actions of Class I fusogens in cell fusion, they insert their fusion loops into a target membrane. Consequently, the action of syncytin-1 is an example of membrane adhesion as it links the two cells together to prepare them for fusion. [6] This step also encompasses the dehydration of the membranes at the site of fusion.

Mitochondria are dynamic organelles with the ability to fuse and divide (), forming constantly changing tubular networks in most eukaryotic cells.These mitochondrial dynamics, first observed over a hundred years ago [1] are important for the health of the cell, and defects in dynamics lead to genetic disorders.
