Marking

 

(biology), the tagging of a group of cells, individual cells, or intracellular structures to study what happens to them subsequently. Marking is used in research on developmental biology, chiefly in embryology. Methods used for marking are in vivo dyeing, 3H-thymidine tagging, and genetic and biochemical markers (transplantation of cells or groups of cells into the embryos of animals of different species, into normal and mutant individuals, or into individuals with different ploidies).


Marking
