An Unusual Karyotypic Observation on Cultured Cells from an Owl Monkey (Aotus Trivirgatus)

Abstract

A cell line, established from a pathological lymph node of an owl monkey, Aotus trivirgatus s.sp. trivirgatus , was found to have two cell populations distinguished from one another by chromosome number. The normal karyotype was present in the population of cells with 54 chromosomes; the other cell population, with 55 chromosomes, possessed a normal karyotype but with one additional abnormal chromosome. The significance of this extra chromosome is discussed. Images Fig p165-b
