Genetic variation within a parthenogenetic lineage

Insect Molecular Biology, 1998
Abstract A clone of the grain aphid Sitobion avenae F. was maintained parthenogenetically over thirty‐two generations ( n = 344) in a constant environment: a new generation being set up by a female selected at random from the preceding

Genetic Lineage Tracing of Beta Cell Neogenesis

2012
Genetic lineage tracing is an invaluable tool to demonstrate and measure neogenesis of beta cells from putative precursor cells. Cre-Lox recombination technology can be used for indelible labeling of a cohort of cells and following the fate of these cells and their progeny in animal models.

Genetic Lineage Tracing of Non-cardiomyocytes in Mice

2020
Genetic lineage tracing is accomplished using bi-transgenic mice, where one allele is altered to express Cre recombinase, and another allele encodes a Cre-dependent genetic reporter protein. Once Cre is activated (constitutive or in response to tamoxifen), the marker gene-expressing cells become indelibly labeled by the reporter protein.

Genetic Lineage Tracing of Biliary Epithelial Cells

2018
Lineage tracing of liver cells is a powerful tool to understand liver embryonic development, healthy liver cell homeostasis, tissue repair, and regeneration. Lineage tracing of biliary epithelial cells (BECs) in the adult liver has been used to assess the contribution of the biliary epithelium to liver injury, regeneration, and disease.

Genetics and the human lineage

2007
Genetics has greatly contributed to current knowledge about the evolution of the human lineage. Immunological techniques and the molecular clock have addressed the time divergence of human and chimpanzee lineages, disproving the late divergence model.
